Printing on remote network

you have two different networks, W2K and NT4.
a daily report is been sent from NT4 network to some W2K printer and printed during night. After closing the Firewall, users on W2K network complain they cannot receive the printout. Note that for Security requirements, you cannot have create trusts relationships or having NT4 net patches on W2K offices. What could you do to allow users on W2K network to have the jobs printed ?
