Can't remotely print unless CUPS server has an account matching remote user

Question

Can't remotely print unless CUPS server has an account matching remote user

I recently upgraded the OS to v10.6.3 and started having trouble printing from remote computers. I have a Canon MP600 connected via USB to an iMac and can print just fine from that computer. Prior to the upgrade I could print just fine from remote computers including both iBooks and Windows XP. In troubleshooting I've discovered that the CUPS server is rejecting all remote computers unless there is a local account with the same user name as on the remote computer. I've used CUPS admin to "Set Allowed Users" to the MP600 under the Administration tab to no avail. I tried both "username" and "@username" but neither works. I've bounced the CUPS server after each change to no avail. Following is an excerpt from the CUPS Error Log. I've obscured the ip addresses.

Get-Printer-Attributes ipp://new-host-4.home:631/printers/Canon_MP600

Can anyone provide insight into this problem?

I can't answer your query since I don't do remote printing, but can suggest that if you want to report this issue to Apple's engineering, send a bug report or an enhancement request via its Bug Reporter system. To do this, join the Mac Developer Program—it's free and available for all Mac users and gets you a look at some development software. Since you already have an Apple username/ID, use that. Once a member, go to Apple BugReporter and file your bug report or enhancement request. The nice thing with this procedure is that you get a response and a follow-up number; thus, starting a dialog with engineering.

I don't think setting allowed users for the printer is the method you want to use. It may, in fact, be counterproductive to what you are trying to do. I think what you want to do is to turn on printer sharing. You can do this by using the System Preference for Sharing. That should allow users on your local network to print. If you have users trying to access the printer from outside you local network, then you will probably want to mark the appropriate check box at http://127.0.0.1:631/admin to *Allow printing from the Internet*. You can fine tune these settings by making manual changes to the cupsd.conf file accessed from the same http://127.0.0.1:631/admin page.

I've been operating with Sharing enabled from the get go. Please note, in my original post I indicated print sharing had been working prior to upgrading to 10.6.3.

I'm still trying to get this to work!
