which controls the orientation of the logical page rather than the physical page, would cause
the logical pages to be positioned one on top of the other when combined with the group=2
option.
Supporting PostScript Printers
Support of PostScript printers is similar to support of other printers, in that the printers must
be defined to the system with the lpadmin command and the appropriate software must be
installed to manage them. PostScript printers may require some additional effort in
supporting fonts and establishing where slow filtering occurs.
Installing and Maintaining PostScript Printers
PostScript printers, like other printers, are installed with the lpadmin command. These
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.
PostScript Page Order Table
Printer Connection Type Page Order
PS serial normal
PS–b parallel normal
PS–r serial reverse
PS–br parallel reverse
The –b specification (used when you select PS–b or PS–br) represents batch, which is
typically used for parallel connections but can also be used for serial connections if you do
not want PostScript printer status messages. The PS and PS–r printer types cannot be used
for parallel connections.
By specifying the –I option of the lpadmin command when configuring a PostScript printer,
you can indicate which content types are handled by the printer without slow filtering. For a
printer on a server system, PS is the correct content type to enter. However, for a printer on
a client system, consider where slow filtering is to occur, because network and system
resource management may be of concern.
By specifying valid content types other than PS, you can force the slow filtering of input to
occur on the server system. Conversely, if you specify a content type of PS, the input will be
filtered locally before the print request is forwarded to the server system for fast filtering and
printing.
To configure a printer on a server system:
/usr/sbin/lpadmin –p ps1 –T PS–b –I PS –m PS
To configure a printer on a client system without local filtering:
/usr/sbin/lpadmin –p ps1 –T PS–b –I simple,daisy,dmd,tek4014,plot
To configure a printer on a client system with local filtering:
