To quickly check if a network-attached printer is reachable (communication can be interrupted because of a lot of things - firewalls blocking the port, misconfigured routing, ....) use the following: the lpd operates on port 515 (see also /etc/services) and the telnet client allows to specify a port:
This will NOT let you establish a connection or print something, but a banner from the printers network interface (usually a JetDirect Card) should greet you. It states the firmware revision, hostname of the printer, etc.. (Sorry, no test hardware to try it, so i have to be a bit vague.) This way you can verify the connection itself is unobstructed.
Another pointer: queues and queue devices are defined in the file /etc/qconfig. This is a clear-text file but it has to be translated into a binary form to be used (/etc/qconfig.bin). /usr/lib/lpd/digest does this, see man qconfig for details.

Hi,
I have Aix 6.1.
Installed the Ricoh Unix print filter, to allow us to print to a Ricoh 5001.
So I send text documents to the printer using the qprt command and set the print job finishing options using the Ricoh commands passed using -o options.
Eg. qprt -Pfin200 -o collate=on -o text... (7 Replies)

cups-lpd
cups-lpd(8) Apple Inc. cups-lpd(8)NAME
cups-lpd - receive print jobs and report printer status to lpd clients
SYNOPSIS
cups-lpd [ -h hostname[:port] ] [ -n ] [ -o option=value ]
DESCRIPTION
cups-lpd is the CUPS Line Printer Daemon ("LPD") mini-server that supports 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) or xinetd(8). If you are using
inetd, add the following line to the inetd.conf file to enable the cups-lpd mini-server:
printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd
-o document-format=application/octet-stream
Note: If you are using Solaris 10 or higher, you must run the inetdconv(1m) program to register the changes to the inetd.conf file.
If you are using the newer xinetd(8) daemon, create a file named /etc/xinetd.d/cups containing the following lines:
service printer
{
socket_type = stream
protocol = tcp
wait = no
user = lp
group = sys
passenv =
server = /usr/lib/cups/daemon/cups-lpd
server_args = -o document-format=application/octet-stream
}
OPTIONS -h hostname[:port]
Sets the CUPS server (and port) to use.
-n
Disables reverse address lookups; normally cups-lpd will try to discover the hostname of the client via a reverse DNS lookup.
-o name=value
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; the examples in the previous section set the "document-format" option to "application/octet-stream" which forces
autodetection of the print file format.
PERFORMANCE
cups-lpd performs well with small numbers of clients and printers. However, since a new process is created for each connection and since
each process must query the printing system before each job submission, it does not scale to larger configurations. We highly recommend
that large configurations use the native IPP support provided by CUPS instead.
SECURITY
cups-lpd currently does not perform any access control based on the settings in cupsd.conf(5) or in the hosts.allow(5) or hosts.deny(5)
files used by TCP wrappers. Therefore, running cups-lpd on your server will allow any computer on your network (and perhaps the entire
Internet) to print to your server.
While xinetd has built-in access control support, you should use the TCP wrappers package with inetd to limit access to only those comput-
ers that should be able to print through your server.
cups-lpd is not enabled by the standard CUPS distribution. Please consult with your operating system vendor to determine whether it is
enabled on your system.
COMPATIBILITY
cups-lpd does not enforce the restricted source port number specified in RFC 1179, as using restricted ports does not prevent 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
definition, remote status reporting to LPD clients may be unreliable.
