Print Spooler won't clear when using Print Server

WinXP Pro SP2
Dell Optiplex SX280
Dell 720 Color Printer

The addition of a Netgear PS121 print server seems to prevent each
print job from being deleted from the spooler after it has printed.
Additional jobs will queue up but cannot be processed.

If I reset the computer the next job in line will print, but again,
cannot be deleted from the queue. I find the same behavior when trying
to print from a Win2000 Pro machine as well.

I haven't been able to determine if this is a configuration problem, a
printer problem, an OS problem or an issue with the PS121. Any ideas?

TIA
