We recently upgraded our Servers from Citrix XenApp 5 Windows Server 2003 (32-bit) to Citrix XenApp 6.5 Windows Server 2008 R2 Enterprise SP1 64-bits.
Mainly we use HP LaserJet 4250tn and some HP LaserJet P4015 printers (Also Xerox Multifunctional printers no problems there).
For the LJ 4250tn we have installed the HP 4250tn PCL5e v 61.74.561.43 and for the HP P4015 we have installed HP Universtal Printing PCL5e v188.8.131.5234.
Often we get the error message "Print driver host for 32bit applications has stopped working". I think this must be a driver issue.
I've change all drivers to the HP 4250tn PCL5e v61.74.561.43. Now we have less error messages but still sometimes. And when this happens the only solution is to reboot de Server.
The error message is:
Faulting application name: splwow64.exe, version: 6.1.7601.17777, time stamp: 0x4f35fbfe

What driver must I use in such an environment whithout getting this error?
