I have a PSC750, which is installed locally on a server - ready to share. I can print locally on the server, but i cannot connet from a client to this printer.
Cups replies, that i am not authorized. But i checked, everybody should be authorized.
Is there a bug in Cups using USB-Printers? Perhaps a Problem with the device-URI?
Thanks, Roger

Just a thought - if you go to localhost:631 on a web page and make sure the printer is published - not just shared then it may help - also check that you don't have a firewall block on port 631

I don't think there is a bug, but it is very confusing. I have an HP PSC4280 which I had some difficulty using from a client.
The first question is, can you access the server from the client, with telnet <server IP address> 631
The second question, if that is OK, is the URI of the printer on the client. In my case, the server "found" the USB printer attached to it, and gave it the name HP_Photosmart_C4200_series_USB_MY797KM03904VP_HPLIP , so I set the URI on the client to be http://192.168.2.2:631/printers/HP_Photosmart_C4200_series_USB_MY797KM03904V... (I'm not sure if this is necessary.)
I also found (later) that I had to uncomment the lines with "octet-stream" in /etc/cups/mime* on client and server.
I found the files /var/log/cups/error_log on client and server gave some indication of problems. In particular, looking at this file on the server will tell you if the print-request ever got to it.
There are some other minor points. After a print failure, the printer seems to be stopped (or disabled) on the client, so one has to start it again on the web-interface.
Also, I think one needs the package hplip installed on client and server, though again I am not sure of this.

Did you not configure the printer in anyway on the client? Because that is what you have to do, as I have said before.
