Im trying to use the Ricoh Aficio C2550 printers at my office

Customer Question

I'm trying to use the Ricoh Aficio C2550 printers at my office from a Mac OSX 10.6 and the machine keeps printing pages and pages of postscript garbage.

I've found that I can use a generic PCL driver and print black and white, but that's not going to cut it.

I've proceeded through step 7 of your instructions, but now I'm stuck. The Ricoh printer is not listed in the default list of available printers.

the only way I've been able to get to it is by entering it's IP Address via the IP tab. When I type in it's IP Address it recognizes it as the Ricoh Aficio C2550 and automatically selects the right PPD. I tested it and still get Postscript garbage. Is there a particular protocol I need to select: IPP, LPD or HP Jetdirect socket?
Expert:  Engineer John C. replied 6 years ago.
You should be able to select PPD.. if no luck try with LPD or IPP, and last with HP.
Customer: replied 6 years ago.
LDP and HP Jetdirect socket result in the postscript errors I described earlier. IPP pauses the print que and prevents anything I send from going through.

Any ideas?
Expert:  Engineer John C. replied 6 years ago.
I will opt out so any other expert can try to help you.

You will receive an email when another expert takes your question. The new expert will see all our previous thread, so no need to explain the issue again.

Thank you
