While there *were* some major changes to the IPP backend in CUPS 1.5 to support streaming of print jobs, many of the issues that have come up have been in the printers/print servers that only implement IPP/1.0 (which was a short-lived experimental version of IPP) and never got it right.  Microsoft has never implemented anything beyond the barest support for IPP/1.0, thus my comments...
