IPP printers don't work with CUPS after update?

[Rich Lott]

Hi 

Thought I'd post this solution to your thread too, if it's useful. From thread 
titled "CUPS not printing via ipp: protocol":

Thank you gborzi!

I have TWO ways to get it working.

1. as gborzi said, on the client machine use Raw Queue driver. This works 
fine, but it means the client has no control over the printer functions (eg. 
quality, media...)

2. same principle, add the printer to the server, using the Raw Queue driver. 
Set the client up with the drivers, pointing to the raw queue. This way the 
client /can/ control the driver settings, and it works too.
