cups has support for the IPP printing protocol, which I've been using on older versions of RHL with the following /etc/cups/printers.conf configuration file: [root@winsucks root]# more printers.conf # Printer configuration file for CUPS v1.1.15 # Written by cupsd on Thu 10 Oct 2002 05:57:21 PM GMT <DefaultPrinter phaser860> Info phaser860 DeviceURI http://phaser860.example.com:80/ipp/ State Idle Accepting Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 </Printer> [root@winsucks root]# When I try this on beta4 (either fresh install or upgrade from 8.0), I get: Can't understand DeviceURI: http://phaser860.example.com:80/ipp/
This is coming from redhat-config-printer, which doesn't have support for this type of URI yet. The queue will still work, however; you'll just have to manage it from the browser interface rather than the configuration tool. The IPP screen on the config tool needs a 'specify URL' bit I guess.
Okay. Then I guess the most pressing problem is that I have a valid cups configuration, yet every time I start cups, redhat-config-printer is spewing errors on the screen (ie, even if r-c-printer isn't immediately extended to support IPP configuration, which I wouldn't really expect given current deadlines etc., it really does need to recognize that existing IPP configs are in fact valid). That's different than previous releases, where IPP w/ cups Just Worked b/c r-c-printer wasn't involved....
Yep, fixed in CVS.
0.6.43-1. Changing to DEFERRED (for when I actually teach the tool about that URI scheme).
