I have a small network with 3 PC’s two running XP and one
windows 98. One HP and one Brother Printer is connected to
the one XP PC. Another epson Printer is connected to the
otjer XP Pc. The printers are all shared on the network. A
downlevel document keep on printing on all of these
printers and I cannot remove this documnet in the printer
spool. Each time the PC’s are switched on a newe downlevel
document appears in the printer spool. How do I stop this
document from printing ?????????????
