Windows 7 client Printer Queue fails when printing to CUPS Server via IPP

A short entry, since if you have setup a cups server and you have set up the Windows 7 clients to print to it via IPP you may find the windows printer spooler some times plays up. We had this for a while with our setup and I could not find a answer. It looks like Microsoft really tries hard for it software to only work with Windows.

I bet there is code inside windows which says if talking to non-windows system add bugs!!

Anyway if you get any of the following in your cups logs:

• Print-Job client-error-bad-request
• windows-ext client-error-bad-request
• Print-Job client-error-bad-request
• Returning IPP client-error-bad-request for windows-ext
• Missing printer-uri, job-uri, or ppd-name attribute

You see the following from windows:

• Print job fails. 
• Event is logged in the Operation Log that shows that the print job was successful. However, the size of the print job is displayed as 0 bytes.
• tmp files appearing in printer spool

 You need a hot fix which has been out since November 14, 2012.
