Programming for Tandem Laser Printers
Programming for Tandem Laser Printers
This subsection describes some of the more commonly used programmable features
of the supported Tandem laser printers. The supported laser printers include:
•
5573 laser printer supporting PCL 4
•
5573D laser printer supporting PCL 4
•
5574 laser printer supporting PCL 5
•
5577 laser printer supporting PCL 5 and PostScript
The information presented here describes how to use:
•
Commands for selecting the printer language you want to use: PostScript or PCL
•
Job-control commands to select the number of copies, simplex or duplex mode,
the paper source, and the output bin, and to separate jobs
•
Page-control commands to set the page size and length; the size of the left, right,
and top margins; and the horizontal and vertical motion indexes
•
Text-printing commands to select a font, the font size, and the orientation, and to
underline text
For complete details of how to use all available PCL commands for the 5574 and 5577
l
aser printers, see the PCL 5 Printer Language Technical Reference Manual. For the
