I have a Linux machine on which I can't seem to configure the printers properly. There are two network printers I'm trying to connect: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong.
I went to Administration > Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as:
socket://[ip address]:9100
I changed these to:
lpd://[ip address]
...per an online tutorial I found, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said "Processing" (and sometimes even "Processing - printing test page, 4%"), but always subsequently displays "Idle - /usr/lib/cups/backend/lpd failed".
Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong? What do I need to do to get these to work and stop getting that "failed" message?
