4 COLOR PLOTTER PRINTER for SC-3000 personal computer Operation Manual

Introduction CVingratuIatinns for selecting this high-quality, luw-cost color ploiier/priiiter! We know this Printer is the ideal output device for home or business use. Its special features include: • A set of simple instructions that allow you to change colors, backspace the pens, reverse feed the paper, and • Four color printout (black, blue, green, and red ), • Standard roll paper (4.48‘ wide by 56meter long). • 38 character per line printing.

3 Background Information The BASIC conmiand to send information to the printer is LPRINT. LPRINT "V" Before printing, the Printer checks to see if the character sent is an instruction (on how to print) instead of data (to be printed). An instruction, for example, might teil the Printer to backspace or change to a different Pen. ConseQuently, some ASCII codes were created as instniciiuns to control printers (and therefore are called "Control Codes”). How do we send instructions to the Printer? To send instructions to the Printer, use "control codes.'' To do this, use the BASIC function CHRS( ). For example, to tell the Printer to backspace (ASCII Code 08), tise the coininand; LPRINT CHR$(08) In a program (or in the "direct mode') and the Printer will backspace. Any ASCII code (control codes as well as data) can be sent to the Printer this way, Appendix C lists the ASCII codes the Printer recognizes. For instance, Appendix C will toll you that the ASCII code for the letter Z is 90 (decimal). If you use the command: LPflINT CHRSOB) Printer will print the letter Z.

Text and Graphic Modes The Printer has two modefe of operation: • TeKt Mode fi>r word processing, note writing,prt^gram listings, and program output. • (iraphic Mode ior generating graphs, pictures , and other visual Text Mode- On initial power-up, the printer will be in Text Mode. When in Oraphic Mode, to return to Text Mode, type: (iraphic Mode. In this mode, you can generate graphs, pictures and other visual creal creations. To put the Printer in (iraphic Mode, send a Control Code 18 (deoimal) to the Printer using LI’RINT. In Graphic Mode, you can move the Pen to any point on tne paper and draw a line tti any other pomi. Think of the Pen as being on a Cartesian coordinate plane, with the running left and right (horiaontall and the Y-axis going up )wn (vcrticall- e is up and to the right, negative is to the left and down the See Figure below. rigin may be set anywhere or the paper. When first entering aphic Mode, the origin is at the left margin and under the Pen.

Care and Maintenance The Printer a very reliable unit that shfiuld give years of satisfactory scnhcc. linwever, there are some definite Do’s and Dniit’sj • Do not manioulate the Pen Holder manuaily. This wilt very easily cause damage to the Printer. He esiiecially careful when inserting and removing the pens. ' The Pen Holder is self-propelled. Do not move it manully. To move it to the right press the PF.N CHANGE Switch. To move it to the left, press LINE FEED. To rotate the Pen Holder press CGLOR SELECT. • Do not oiieraie the Printer without Pens. Leave a dry or liruken pen in the Holder until you can replace il. • Cap Ihe pens and return them to their case when the Printer •Do not alleinpt to use Pens or paper not designed for (his Printer. The Printer contains a self-test routine. To see all the characters, lum the Power Switch on while holding down the LINE FEED Switch.

4 Using the Plotter /Printer Automatic Start-up Sequence Uncc the tenter is properly connected, it vrill execute a short, buiit-in routine that resets the I’cn Holder and draws four small boxes in each availaide pen color on power-up This allows you to be sure that each I’en has enough ink and is drawing correctly before you begin using the Printer. Automatic Start-L'p Sequence After the four Ixixes ate drawn, the Pen will return to the left margin. The printer will llien be in Text Mode and ready for oiieratioii. Manual Operation You can change pen color with the COLOR SELECT key and advance the paper using the LINE FEED key. Program Control The printer can be controlled entirely from within a BASIC program. Note that you can use Control Codes (CHR$( )) lo send instructions to the Printer as w*ell as data to be printeti. In this seetinn, we'll describe the Control Codes in sequence starting fromCHRS ((IS) through CHK$ (US). Then wc'll describe the Graphic Commands listed alphabetically. With each code or command, we’ve included a short example. The examples serve two purposes. First, they show how to use the command being discussed. Second, they show how to use combinations of commands to draw with the Printer, Once you see how

simple it is to proaram the Printer, ynu can write your own graphic programs. (For more involved programs, sec Apiwndix A.) Control Codes CHK$ (8) Backspace (Text Mode) This command backspaces the Pen one character at a lime. CHK$ (S) ia very useful when you need to underline. Example 10 LPHINT "R" ! 20 LPRINT CHR»CS) S 30 LPRINT CHRSfSS) This program will prim the letter A, then backspace (line 20| and print an underline. CHK$ (11) Reverse Line Feed (Text Mode) CIIRS (11) moves the paper backwards (rererse) one line at a time. This is often used for superscripts. 10 REH SUPERSCRIPT DEMONSTRfiTION 20 LPRINT •’2" ? 30 LPRINT CHRSdl > t 40 LPRINT '2"? 50 LPRINT CHR$<10) !

There arc other commands that allnv.' you to print words in (jraphic Mode, but CHKS (17) is the easiiesl way to change to Text Mode and print text beiween graphic material Kxample 20 LPRINT CHRSC17) CHR$ (29) Rotate Pen Holder (Text Mode) 'ITiis command advances the Pen Holder one color. CHR$ (2S)) used lo change color from Text Mode and you Tiiiist keep trac what color is next. If you want a color beyond the next I’oedi vou may use the command more than onece. Example 10 LPRINT CHR6C29) Graphic Commands The following commands can be used in (iraphic Mode only.

A Return to Text Mode (Reset) Thi<i command moves the Pen Holder to the left margin (without drawing a line and without vertical movement) and returns the Printer to text Mode. In this case, the Origin is also re-dcfmed (reset) as the left margin. Example 10 LPRINT CHR»<1S) 20 LPRINT "fl" 30 LPRINT "R" This example will pul the Printer inlu Graphic Mode (line 10). Lit 20 will return the Printer to Text Mode. Line 30 will prim the letter A. c Change Color color IS a numeric expression front ft to 3 • color is optional; if omitted, 0 is used. If you instaUed Ihc Pens according to the suggested sequence earlier, then 0 Black. 1 = Red, 2 Green, and 3 Blue. If not, then the Pen you installed m Pen i*usilion P 1 will determine the color whe.i you send the Color command tu the printer, 10 LPRINT '‘Cl“ Remarks : See APPEND IX D |

The destination point (e.g., the point where the line ends) is in the form x.y where X and Y are a coordinate pair with respect to the If more than one pair of coordinates are specified then the line will be continued to the second point, then to the third point, etc. X and Y arc values between.999 and 999.

Remember that the paiier is 4«n steps accross and a.s deep as you wish (up lo 999 steps). Since you didn’t siiecify a different Origin, the Pen started at U.U. The comers of the box are at 0,0 0,100 100,100 and 100,0, H Return to Origin (Home) The 11 command will move the Pen lo the Origin without drawing Example 10 LPRINT "H" Set Origin (Initialize)

The end point is determined dy measuring up X units and right \ units, (nr left and down if X and Y are negative). Once ihe Pen is at this new position, the line can be continued (o another point by supplying another pair of X-Y values.

Read line 30 like this: "From where you are, draw a line to the point that is 0 steps to the right (in the X-direction) and 100 steps up (in the Yalirection). Then from that point, draw a line that is 100 steps to Ihe right and 0 steps up, then a line from that is 0 steps to the right and ion steps down. Finally draw a line that is 100 .steps to the left and 0 .steps up."

The S command lets you specify the size of the character drawn with the P command, sise may be a numeric expression between 0-63, 0 draws the smallest characters size (80 characters per line), 63 the largest (I character per line). Use this formula to determine the size of printed character in relation to the numeric value you specify: cpI 80,'(size 8- 1) where cpl is the number of character.s per line and size is the numeric value you specify with the S command. r Remarks : Sec APPENDIX D | Q Rotate Print Direction Q ilirfi'U'in fiireclion specifies which direction you wish printing to be and is a numeric expression from 0 to 3. dirprtion is optional; if omitted, 0 is used. On ijower-up (in Text Mode), QO is used. However, when you enter Graphic Mode, you can specify one of four dircctinns for character printing. See Table below.
