Since I filed ticket:1813 I've had upstream feedback from the patch I made for [http://cups.org/str.php?L3197 STR #3197], a CUPS denial-of-service bug I discovered, and there was a part I'd missed. :-(

I've built cups-1.4-0.b2.18.fc11 to fix that.

Please tag it for Fedora 11. Sorry this all seems so last-minute. I had intended to do much more testing of the printer stuff in the last couple of months but have been unexpectedly and unavoidably busy with other work.
