We are using iPrint 3.11 on W2K SP4, Zen4IR5 agent, NW6, NW Client

We have several workstations that require LPT1 LPT2 and LPT3 capturing to
different printers. I set this up thru the iPrint client on the iCapture
tab and it works fine - until the user reboots their workstation. When
they go to print they get an error. If they go into the iCapture tab it
appears that the captures are still set up, however if they remove the
capture and then resetup the capture then printing works again.

Any ideas? I see there is a 3.12 client now but it makes no mention of
this problem.
