Recently we upgraded our OS from 7.3 to 7.3-2, upgraded Multinet from 4.4 to
5.0, we changed from AS4100 to ES40, increased network card speed from 10
half to 100 full and upgraded our application.

Yes, a lot of changes

After the above changes, we notice that some of the printer are not printing
so well. For example, a printer will print about 8 pages, then hangs, then
start to print one page at a time.

This seems to happen only to older printers. For example, this was happening
to HP4100, but when we replaced it with HP4350 everyting workes fine.

Any help would be appreciated.
