Apparently, not all printers will work with a Mac computer. I found this out the hard way this morning. I spent about 3 hours configuring and troubleshooting a Mac mini to work with a Ricoh Aficio MP 5002 printer. Everything seemed okay, come on it was simple - add the IP address into the LPR settings, pick your driver and your done. No!, it wasn't that easy for me. Every time I sent a print job to the printer I was getting an error of 91:error. I looked up "91:error" and this is what I got for the cause and solution:
I couldn’t understand why I was getting “printing was canceled by the auto job…”. Like, come on the user was printing fine on another printer but this printer was only for the Marketing department [which are all Macs :)] and I needed to take him out of the address book and place him into another printer for tracking purposes. Well, three hours in and I was like AHHHHHHHHHHHHHHhhhh!!!! pulling my hear out of my head and trying to figure out what the issue was. I told the user that I needed to look into the settings between both printers. Now, keep in mind both printers are not the same model, but come on it’s a printer Mac or PC should be able to print with no issues, right?
I went back to my cave and brought up both printer’s settings and compared them. I noticed that one of the printers have the following option and it was allowing PostScript to print to the printer, which PS or PostScript drivers are well known and used for Macintosh computers.
The other printer did not have this option at all, so I had to give the user access to the printer with the PostScript feature enabled. What a pain. I still need to figure out how to get a Mac computer to print to a printer without this option. Back to searching and figuring it out.
