cups-lpd(8) Easy Software Products cups-lpd(8)NAMEcups-lpd - receive print jobs and report printer status to lpd clients
SYNOPSIScups-lpd [ -o option=value ]
DESCRIPTIONcups-lpd is the CUPS Line Printer Daemon ("LPD") mini-server that sup‐
ports legacy client systems that use the LPD protocol. cups-lpd does
not act as a standalone network daemon but instead operates using the
Internet "super-server" inetd(8). Add the following line to the
inetd.conf file to enable the cups-lpd daemon:
printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd
If you are using the newer xinetd(8) daemon, add the following lines to
the xinetd.conf file:
service printer
{
socket_type = stream
protocol = tcp
wait = no
user = lp
server = /usr/lib/cups/daemon/cups-lpd
}
OPTIONS
The -o option to cups-lpd inserts options for all print queues. Most
often this is used to disable the "l" filter so that remote print jobs
are filtered as needed for printing:
printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd-o document-format=application/octet-stream
The example shown resets the document format to be application/octet-
stream, which forces auto-detection of the print file type.
COMPATIBILITYcups-lpd does not enforce the restricted source port number specified
in RFC 1179, as using restricted ports does not prevent determined
users from submitting print jobs. While this behavior is different than
standard Berkeley LPD implementations, it should not affect normal
client operations.
The output of the status requests follows RFC 2569, Mapping between LPD
and IPP Protocols. Since many LPD implementations stray from this defi‐
nition, remote status reporting to LPD clients may be unreliable.
