But those aren’tall. Dependingon whichprinteremulationyou are using, you can tell the StarLaserPrinter4 to movethe print positionverticallyor horizontallyin incrementsof:
1/10,1/12or similarfractionsof an inch (pitch settings), 1/48,1/60,1/72,1/120or 1/216inch (lineor columndefinitions), 1/300inch (dots),or
1/720inch (tenthsof a point).
These incrementsreflect the history of twentiethcentury printing.Pitch, referringto thenumberof charactemprintedin eachhorizontalinch,derives from how typewritersspacetheir charactem.Lines and columnswere first used by earliercomputerprintem(on whichthey are calledhorizontaland verticalmotion indexes).You alreadyknow aboutthe Star LaserPrinter4 being able to print 300 dots to the inch. And the unit by whichtypesetters have measuredtext for centuriesis thepoint, about l/72nd of an inch.
