Hexadecimal dump

This feature is useful for programmerswho are debuggingprinting pro- grams and want to see the actual codes the printer is receiving. (Some computemchangethe codesthe programmerintended.)

Inthismode,alldatareceivedwillbeprintedin ahexadecimaldumpformat, ratherthan the controlcodesbeing actedon as commandcodes.

This mode is accessedwith the followingprocedure:

1. While holding both the(PAPER FEED)and(	SEJAE~~CT	)buttons down,
turn power ON. A beep tone will be heard.

2.Beginprinting.In place of the usual printoutyou will get a formatted dumpshowingexactlywhatdatatheprinterreceives.Eachlinepresents sixteencharacters,theirhexadecimalcodestotheleft andprintablechar- actersprintedon the right.

3.At the end of the hexadecimaldump, set the printer off-line with the ( ONLINE ) button.This is necessaryto print the last line.

The followingBASICprogramis a simpletest you can run in hexadecimal mode:

10LPRINT WIDTH “LPT1 : “ .255

20 FOR 1=0 TO 255

30 LPRINT CHR$(I) ;

40 NEXT I

50 LPRINT

60 END

If your system passes the codes directlyto the printer without changing them, you will get a printoutlike Figure2-5.
