LPD Outbound Gateway Supervisor
The LPD Outbound Gateway supervisor, pdspvlpr, transfers print job
requests to remote servers and printers using the Line Printer Daemon
(LPD) protocol. To do this, it converts Advanced Printing Software jobs and
their attributes to an LPD request and sends the request to a specified
LPD server.
The LPD supervisor can print jobs on the following:
• Printers connected to remote hosts when those hosts are running line
printer daemon (lpd) software, and the host is configured to accept
remote jobs
• Printers that directly support LPD protocol
The LPD supervisor is particularly useful for accessing printers that are not
supported by the regular print system supervisor (pdspvr). For example,
if your environment includes legacy printers that are connected to UNIX
hosts, and those printers require specialized UNIX filters, you might be able
to use the LPD supervisor to pass Advanced Printing Software jobs to them.
Similarly, if you want to submit print jobs to any printers connected to hosts
not running Advanced Printing Software, you might be able to use the LPD
supervisor to pass print jobs to them.
11.1 Specifying Protocol Extensions
The LPD supervisor can communicate with a remote print server using one
of several popular protocol extensions:
• 1179–RFC1179 (LPD) protocol with no extensions
• Solaris–LPD protocol with Sun Solaris extensions
• Digital UNIX–LPD protocol with Tru64 UNIX extensions
• Xerox –LPD protocol with Xerox DocuSP and DocuPrint extensions
Specify the most appropriate protocol designator when you create a physical
printer object on the LPD supervisor. That will allow users to specify job and
document options that take advantage of the various protocol extensions
that are available on your LPD server or printer. Tables 11-1 through
11-4 list command options and arguments available for the protocol and
supported extensions.
