we have some documents (.doc and .pdf - confidential, so i can't share)
that can't be printed on a upper mentioned printer, if it was installed per
iPrint on WinXP.

If i install the printer manually, there are no problems. Everthing works
fine. As soon as i distribute the printer by iPrint. Various applications
DoS themselves.
E.g. MS Word 2k3. You can print it once. If u try to print it again, Word
hangs with 100% CPU. Same problem with Acrobat 7. Printing to another
printer works fine.
This means, the printer is causing this problem. BUT: if i install the same
printer with the same driver version manually, everything is fine. So,
iPrint is causing the problem!

Need a solution urgently.
