Introduction The Epson LX-90™ printer with the PIC for parallel interface sys- tems combines low price with the high quality and advanced capabili- ties formerly available only on more expensive printers. The LX-90 User’s Manual tells you how to set up your printer.
Chapter 1 Installation and Operation After you have set up your printer and loaded the paper (following the directions in the LX-90 User’s Manual), you are ready to plug in your Printer Interface Cartridge (PIG™) and begin printing. Inserting the Printer Interface Cartridge Inserting the PIC is easy.
Now that the PIC is installed, you need to change the settings of three small switches, called DIP switches, in the back of the printer, Figure 1-2 shows where the DIP switches are. Figure l-2. DIP switch location The functions of these switches are explained in detail in Appendix D, but all that you need to do now is turn three of them on.
2. Hold down the LF button on the control panel while you turn the printer on with the power switch. The LX-90 begins printing letters, numbers, and symbols in the draft mode. It won’t stop until you turn it off or until it gets near the end of the paper.
Control Panel After connecting your LX-90 to your computer, turn on the printer and look at the control panel, which is shown in Figure l-4. I Figure 7-4. Control panel You have already used the control panel for a special purpose, printing the self test.
The other two buttons, FF and LF, work only when the printer is off line (when the ON LINE light is off). If the ON LINE light is on, press the ON LINE button before you use these. l FF (Form Feed)-advances continuous paper to the top of the next page or ejects a single sheet of paper.
Chapter 2 SelecType The LX-90 enables you to use a feature called SelecType to produce five special typestyles: Typewriter-style Near Letter Quality, Emphasized bold printing , Double-strike bold printing, Conpressed narrow printing, or Elite printing .
Figure 2-1. Turning SelecType on When you press the ON LINE and FF buttons, the LX-90 signals in three ways that SelecType is on. l The printer beeps. l The READY light turns off. l The ON LINE light begins flashing. Selecting typestyles In SelecType, each button has a function: l ON LINE selects typestyles.

SelecType modes Mode Typestyle 1 NLQ ABCDEFGHJIJKLMNopqrstuvwxyz 2 Emphasized ABCDEFGHIJKLMnopqrstuvwxyz 3 Double-strike ABCDEFGHIJKLMnopqrstuvxy z 4 Compressed ABCDEFGHIJKLMnopqrstuvwxzyz 5 Elite ABCDEFGHIJKLMnopqrstuvwxyz 2. Press the ON LINE button the number of times indicated in the mode column.
Now, run the program by typing RUN and pressing RETURN, or print your file or document by following the printing instructions of your software. The LX-90 will print your example in standard single- strike printing, as shown below: This is an example o f LX-90 printing .
Mode Combination Two of the SelecType modes (NLQ and emphasized) can be com- bined to create an impressive effect. If you want to see this combina- tion, turn your printer off and back on and follow the instructions below : 1. See that the ON LINE and READY lights are on.

Chapter 3 Elements of Dot-Matrix Printing and Computer/Printer Communications This chapter is for those of you who want to know something about how your printer works.
Other Pitches In addition to pica, in which there are 10 characters per inch, the LX-90 can also print in other widths, or pitches. It does so by reducing the distance between pin firings. In the elite mode it prints 12 charac- ters per inch and in the compressed mode it prints slightly more than 17 characters per inch.
NLQ Mode The preceding examples are in the I-X-90’s draft mode, but the LX-90 also has the high-quality NLQ (Near Letter Quality) mode that you have seen in previous chapters. The NLQ letters are more fully-formed than the draft letters because they are made up of many more dots, as you can see below.
ESCape and ASCII The details of printer-computer communication are complex, but for most purposes all you need to know is that the computer sends a series of codes (each consisting of one or more numbers) to the printer, and the printer interprets them.
Chapter 4 PIC Features The next four chapters describe many of the printing features of the PIC. You can read these chapters if you wish, but you may not need to. Whether or not you use the rest of this manual depends upon your expertise, your interest, and the software you plan to use.
printer for you and all you have to know about the printer is how to turn it on and how to load paper. If you need help with the installation program for your software, see Appendix E. Running BASIC Programs This section describes how to run the BASIC demonstration pro- grams in this manual; it is not a tutorial in BASIC programming.
Pica Printing The first exercise is a simple three-line program to print a sample line of characters in pica, the standard pitch. Enter this program: 40 FOR X=65 TO 105 50 LPRINT CHR$(X); 60 NEXT X: LPRINT: LPRINT Now run the program. You should get the results you see below, 10 pica characters per inch.
Now run the program to see the line printed in compressed mode. Cancelling Codes As you saw in the third version of the print pitch program, you must cancel a code when you don’t want it any more. With very few exceptions, the LX-90 modes stay on until they are cancelled.
you may have turned on, and the current position of the print head becomes the top-of-page setting. Some of the demonstration programs end with a reset code (Escape “a”) so that the commands from one program will not inter- fere with the commands in the next one.
Enter and run the following program to see how the NLQ mode is turned on by an ESCape sequence: NEW 10 LPRINT CHR$(27); "x"; CHR$(l); 28 FOR X=65 TO 105 30 LPRINT CHR$(X); 40 NEXT X: LPRINT ABCDEFGHINKLMNOPQRSTUVWXYZ[]ˆ_`abcdefgh i Note that you use a lowercase x, not a capital X, in line 10.
Chapter 5 Print Enhancements and Special Characters Besides the pitches (pica, elite, and compressed) covered in Chap- ters 3 and 4, the LX-90 offers many other typestyles. Emphasized Mode In the emphasized mode the LX-90 prints each dot twice, with the second dot slightly to the right of the first.
Emphasized works only in draft pica and NLQ modes. In elite and compressed the dots are already so close together that even with the reduced print speed, the LX-90 cannot fire, retract, and again fire the pins quickly enough to print overlapping dots.
Expanded Mode Perhaps the most dramatic mode on the LX-90 is expanded. It pro- duces extra-wide characters that are good for titles and headings. For this mode, the dot pattern of each character is expanded and twice as many dots are printed.
When you run the program, your printout should match the one below, showing that the two modes combine with no trouble. This is standard printing . Emphaasize d expande d A later section in this chapter explains a special ESCape code, Mas- ter Select, which allows you to control six features with one ESCape sequence.
Master Select The LX-90 has a special ESCape code called Master Select that al- lows you to choose any possible combination of seven different modes: pica, elite, compressed, emphasized, double-strike, expanded, and italic.
In this program, you can use any number you calculate by using the formula above, but remember that emphasized can’t combine with compressed or elite. If you try to combine emphasized with either of the two narrow pitches, you won’t harm your printer; it will simply use a priority list in its memory to determine which mode to use.
Now that you see how to use the ESCape sequences for superscript and subscript, you can devise your own examples. International Characters As you know, languages other than English require a few extra characters. The LX-90 has provided for printing in many languages by having nearly 100 international characters in its ROM (Read Only Memory).
Table 5-l. International characters in NLQ mode Table 5-2. International characters in draft mode Table S-3. International characters in draft italic mode The number at the top of each column in the tables is the ASCII code that prints the characters in that column.
Once you have selected an international character set with the DIP switches or the ESCape “R” code, you can use the tables to see which keys on your standard keyboard can produce the international char- acters you want.
Special Graphics Character Set The LX-90 printer’s Read Only Memory (ROM) also contains the 32 graphics characters that you see in Figure 5-1. Figure 5-l.
You can change pitch and weight with the graphics characters just as you can with the other characters in the ROM of the LX-90. The characters in Figure 5-l are printed in expanded elite.
Chapter 6 Page Formatting Although the LX-90 printer has many sophisticated commands to set margins, line spacing, and horizontal and vertical tabs, this chap- ter won’t take up your time with extensive discussions of these because most are taken care of by applications programs.
A program like this also allows you to choose the margins you prefer for program listings. Just remember that once you run a pro- gram that sets margins, those margins are in effect until you change them with new margin commands or turn off or reset the printer.
The standard line spacing is the only one you need for almost all printing of text, but in some cases you may want to increase or decrease the space between lines.
The centering command centers a line of text between the margins. This is handy for headings, titles, and captions. Right justification is the opposite of left justification. The right mar- gin is even and the left is not. Auto justification puts extra spaces between words where necessary so that both the left and right margins are even.
Chapter 7 User-Defined Characters The LX-90 has several hundred different characters stored in its Read Only Memory. Although this number includes draft, Near Let- ter Quality, international, and graphics characters, sometimes you would like to have a few more.
Your user-defined characters can be utilitarian or imaginative, any- thing from a scientific symbol to script letters for your initials. Just follow the simple steps below. The only restriction on your creativity is that the characters you define must follow the same rules that govern the rest of the characters printed by the LX-90.
Figure 7-2. Grid for designing draft characters Because the last two columns are reserved for the space between characters, they are not included in the grid. And since most charac- ters do not use the bottom two rows, a heavy line indicates the usual lower limit for an LX-90 character.
Definition program 1 The BASIC program below will help you translate your design into a character your LX-90 can print. Type it in now so that you can run it soon.
Running the program Now run the program. For each of the nine columns, the program asks for the numbers of the rows in which you want dots to appear. Enter the row numbers one at a time, pressing the RETURN key after each one. When you have entered all the numbers for a column or when you want no dots in a column, press RETURN without a num- ber.
Figure 7-5. Using the bottom eight rows Definition program 2 Once the character looks right, type in the next program. The pro- gram as listed creates the symbol for Mercury, but you can use it for any characters you create if you make one or two changes explained after the program listing.
210 DATA 112,8,0,138,116,138,0,8,112 220 DATA 58,68,2,128,0,128,2,68,58 Check your work by making sure that there are nine numbers in each DATA line and that the numbers are separated by commas. To define more than one character, use the total number of charac- ters you are defining instead of the 1 in line 100.
NLQ grid Because the NLQ characters can use as many as 18 dots vertically and 12 dots horizontally, you plan your designs on a different grid than the one for draft characters. Figure 7-6. Grid for NLQ characters On this grid you can use any numbered line or space.
Figure 7-7. Data numbers for one column To calculate the data numbers for this column, note which dots are used in the top group (the top eight positions) and add their values together. Then go down to the middle group (the next 8 positions) and add the values of any dots that are used there.
Figure 7-8. Musical design and data numbers If you look at each column individually, you can see how the data numbers are calculated. NLQ definition program 1 Now type in and run the following program. It has the data num- bers for the musical design.
NEW 10 LPRINT CHR$(27)"x"CHR$(l) 20 LPRINT CHR$(27) ":"CHR$(0)CHR$(0)CHR$(0); 30 LPRINT CHR$(27)"%"CHR$(l)CHR$(0); 40 LPRINT CHR$(27)"&"CHR$(0)"<<.
NEW 10 J=1: IF J>3 THEN A=58 ELSE A=60 20 LPRINT CHR$(27)"x"CHR$(1) 30 FOR X=58 TO 63: LPRINT CHR$(X)" ";: NEXT X 40 LPRINT CHR$(27) ":"CHR$(0)CHR$(0)CHR$(0) 50 LPRINT.
Chapter 8 Introduction to Dot Graphics The dot graphics mode allows your LX-90 to produce pictures, graphs, charts, or almost any other pictorial material you can devise. Instead of using the standard letters and numbers, the graphics mode prints dots column by column and line by line.
INSTALLATIONS BY MONTH 10 0 U N I T S 0 JUL AUG SEP OCT NOV DEC The quickest and easiest way to print graphics on your LX-90 is to use a commercial graphics program. With such programs you usually create an image on your monitor or TV screen and then give a com- mand to send the image to the printer.
In the main graphics mode, however, the LX-90 prints only one column of pins for each code it receives, and it uses only the top eight of the nine pins. Therefore, your graphics program must send codes for dot pat- terns, one number for each column in a line.
The graphics command requires more than one number to specify how many columns to reserve because as many as 1920 columns are possible in graphics printing. Since the LX-90 doesn’t use decimal numbers larger than 255, the graphics mode command uses two num- bers for reserving columns.
Figure 8-2. Calculating numbers for pin patterns With this numbering system, any combination of the eight pins adds up to a decimal number between 0 and 255, and no numbers are duplicated.
WIDTH Statements Some software (including IBM Personal Computer BASIC) auto- matically inserts the control codes for a carriage return and a line feed after every 80 - 130 characters. This insertion is usually no problem with text, but it can spoil your graphics.
10 WIDTH LPRINT 255 20 LPRINT CHR$(27)"A"CHR$(7) 30 FOR R=1 TO 3 40 LPRINT CHR$(27)"K"CHR$(100)CHR$(0); 50 FOR X=1 TO 50: LPRINT CHR$(85)CHR$(42); 60 NEXT X: LPRINT 70 LPRINT CHR$(.
Density Varieties Although all the examples so far in this chapter have been in the single-density graphics mode, the LX-90 offers five other eight-pin density modes and two nine-pin ones. Nine-pin graphics is not neces- sary for most uses, but you can find its command (ESCape "^") in Appendix B.
Reassigning Code The LX-90 has a graphics command that changes one graphics mode to another. You can use it with many commercial graphics soft- ware programs to change the density and shape of your printouts. The code is ESCape “?s” n, where s is one of the four alternate graphics codes (K, L, Y, or Z) and n is the number of the new code (O-6).
Once you have chosen the number of columns you want to use, you can have your program do the calculations for you with the fol- lowing format: CHR$(27)"L"CHR$(N MOD 256)CHR$(INT(N/256)); N is the total number of columns you want to specify.
lines, but no dots can overlap. In low-speed double density dots can be placed on vertical lines and they can overlap. Now look at the figure designed for high-speed double density. It should point you in the right direction for your own designs. Figure 8-4.

First line of arrow figure The numbers for the second and third lines were calculated in the same manner. Once the numbers for the pin patterns are calculated, they go in DATA statements, separated by commas.
In this program the number 128 in the DATA statements signals the end of a print line. This is the reason for the IF-THEN statement in line 610 that skips to line 650 and causes a line feed. The other special technique used in this program is found in lines 620 and 630.
Notice that the first line stores the whole graphics command in a single string variable. In order to do this you must put plus signs between the elements of the command. Once you have done this at the beginning of the program, each time you enter LPRINT G$; you have issued the graphics command.
Appendix A LX-90 Characters This appendix is a listing of the characters produced by the decimal codes from 0 through 255. For each code the listing provides the deci- mal number (Dec), the hexadecimal number (Hex), and a printout of the character that is printed by that code (Char).

Appendix D DIP Switches and Interface Several tiny switches called DIP (for Dual In-Line Package) switches are in the back of your LX-90 printer. These switches control a number of important printer functions. This appendix also describes the interface.
Always turn the power OFF (with the switch on the right side of the printer) before you change the setting of any of these switches. Any changes made while the power is on will be ignored until you turn the printer off and back on. So set all switches with the power off.
Switch 1-5 controls the paper-end detector. When it is ON, the detec- tor is inactive, causing printing to continue when the printer is out of paper. When it is OFF, the printer stops when the end of the paper passes the paper-end detector.
Interface The PIC uses an &bit, Centronics ® -compatible, parallel interface. Connector pin assignments and a description of respective interface signals are shown in Table D-3. 1 2 3 4 5 6 7 8 9 1 0 11 12 Return Direc. Pin Signal tion Description 19 STROB E IN STROBE pulse to read data in.

4. Data transfer must be carried out by observing the ACKNLG or BUSY signal. (Data transfer to this printer can be carried out only after receipt of the ACKNLG signal or when the level of the BUSY signal is LOW.) 5. Under normal conditions, printer cable pins 11, 12, and 32 are acti- vated when the paper-out condition is detected.
Appendix E Troubleshooting and Advanced Features This appendix presents explanations of the LX-90’s advanced fea- tures and solutions for possible problems. If you have trouble or want to know more about some of the LX-90 features, consult the appropri- ate section in this appendix.
Reset codes Some software sends a reset code before it begins printing. This cancels any SelecType settings. If you find that SelecType does not change your printing, the reset code is probably the reason. The solu- tion is to use the installation program for your software to remove all codes from the initialization sequence.
Suppose that you have set emphasized and NLQ Modes and then you decide that you don’t want emphasized. You can either cancel all the modes and reset NLQ, or you can use the following steps to cancel emphasized and leave NLQ. 1. See that the ON LINE and READY lights are on.
If the printer beeps and stops printing when it is not out of paper, turn the printer off and check to see if the paper is loaded correctly. If the paper is loaded correctly, turn the printer back on and try to print again. If the printer beeps and does not print again, take it to a qualified service person.
Data Dump Mode The LX-90 has a special feature that makes it easy for experienced printer users to find the causes of problems. Called the data dump mode, it gives a printout of exactly what codes reach the printer.
The first code in line 0000 is hex 46, which is the same as decimal 70, which is the code for “F”; therefore “F” is printed in the first position in the guide section. Then, because there is no semicolon in line 20, BASIC sends a carriage return and a line feed, hex codes OD and OA.
The data dumping capability can help you find problems and debug programs quickly. 00 01 02 03 04 05 06 07 08 09 OA OB OC OD OE OF 10 11 12 13 14 15 16 17 18 19 1 A 1B 1 C 1D 1E 1F 20 21 22 23 24 25 2.
