Two importantdetailsmakeLaserJetII commandsdifferentfromthe other
printeremulations.First, all Escapesequencesend with a capitalletter. If
youdon'tmakethelastcharacteruppercase,yourprinterwon'tknowwhen
the Escapesequenceends and will treat followingcharactersas part of the
same command.
Second,in LaserJetII commandseachnumbcrorcharacteryouput afterthe
cESC> codeis an actualASCIIsymbol.Withtheothcremulations,usually
any number you put after an <ESC> code identifiesa character in that
position in the ASCIItable.
For example,the LaserJet11commandthatsets the rightmarginto column
65 is:
<ESC>&a 65 M
whichyou wouldcodein BASICas:
10 LPRINTCHR$ (
27 ) ; "&a65M"
That command sends your printer the symbols
"6"
and "5," which its
LaserJet11programinterpretsas the columnnumber.
HowcvcrifyouwereusingEpsonEX-800emulation, t hecommandthatsets
the rightmarginlookslike this:
<ESC>Q 65
whichin BASICyou wouldwrite this way:
iO
LPRINTCHR$ (27) ; "Q";CHR$ (65)
Thatcommandsendsthepnntcr whatevercharacterhappensto be in ASCII
position65. Your printer'sEpsonProgram,though,interpretsit only as a
decimalnumbermeaningcolumn65.
