Installation and maintenance of PostScript printers

PostScript printers, like other printers, are installed with the lpadmin command.

PostScript printers must use the PS interface program, requested by specifying -m PS on the lpadmin command line.

Note: The printer type and content type of a PostScript printer must be consistent with the printer type used in PostScript filters. Therefore, install your PostScript printers with a printer type of PS, PS-b, PS-r, or PS-br, and a content-type of PS.

The PS printer types serve two functions. First, they cause the print service to activate the correct fast filter to communicate with the printer. PS and PS-r are used to communicate with printers connected via a serial port; PS-b and PS-br, to communicate with printers connected through a parallel port. Second, the PS interface creates a PostScript banner page for PS printers. The banner page is printed last if the printer type is PS-r or PS-br, and the pages of the document are printed in reverse order. The printer type is specified with the -T option to the lpadmin command.
