changingthe actualmeaningof a "line".Whenyou increasethe line depth
youeffectivelydecreasethenumberof linesper inch,andincreasethepage
length.
The commandyou send to set the line depthlookslike this:
<ESC>&?n C
(notethatthecharacterafterthe"&"is a lower-case"L")in whichforn you
can entera numberfromOto 336.If n is zero,lineswillbe printedon top of
each other, and if 336,they will be printed7 inchesapart.
Moving the PRINT position horizontally
You can use three differentunits to move the print positionhorizontally:
columns(space-widths), d ots(each l/300th of an inch),or tenthsof a point
(decipoints).Bothcolumnsand decipointscan be fractionsto two decimal
places, such as 45.75 dccipoints—which provides a great degree of
accuracyfor graphicsapplications.
Moreover,for eachof theseyoucan movethe printpositionhorizontallyin
two ways.Youcan moveabsolutely fromthe leftedgeof the page.Or you
canmoverelatively, a wayfromthecurrentprintposition.To showyouwant
to moveawayfromthecurrentprintposition,youputa plus(+)or minus(–)
signbeforethe numberof units you want to move.
If yousend a commandthatwouldput theprint positionoutsideeitherside
margin,theLaserPrinter8 willlet youdojust that.However,youcan'tsend
the print positionfurtherthan its printablelimits at the edgesof the page.
Horizontal moves: by columns, decipoints and
dots
To move the print positionhorizontallya numberof columns, send the
command:
<ESC>&a n C
in whichfor n youenterthe numberof columnsyou wishto movethe print
position. So to moveto column45 you send the command:
<ESC>&a 45C
Butto move45 columnsto the rightof the currentprintposition,yousend:
<ESC>&a +45C
