I have a recurring problem in a computer lab that is vexing me. The
installed iPrint printer disappears from the list of installed printers on
numerous workstations. Has anyone else seen this problem? If so, I am
very interested in solutions because I am out of good ideas.

The workstations in the lab are Dell Optiplex GX-270 –w- XPsp2,
client 4.91sp3 and ZFD 7.
