Re: Net printers occasionally consuming high CPU usage -- MIDRANGE-L

Another solution for you is to make sure you have loaded a
"Printing" ptfs that are not in the cume's. Don't ask me why ibm
does not put ALL printing ptfs in the cumes(yes-we all do print!),
but they don't. In the IBM Knowledge Base, in the "Print" section, there
are documents like:
V4RxMx Ptf Listing for AFP Printing
V4RxMx Ptf Listing for HPT Printing
V4RxMx Ptf Listing for TCP/Lan Printing
V4RxMx Ptf Listing for HPT AFPDS to Ascii
any ptf listed with (1000) after the ptf number is not on a cume.
Some ptf's are in multiple documents.
btw - many of the same docs exist for V5RxMx.
