Printing through firewalls
Posted on 2004-09-02
I am trying to configure some local print queues on a Citrix server farm that are hosted by my client for a third party company. The print queues are for a number of different HP Printers (4000, 4050, 8000, 8100).
Firewalls are present at both ends of the link between my client (Checkpoint FW) and their third party associate (PIX FW).
I have tried creating queues on the Citrix servers for the HP printers, using a Windows 'Standard TCP/IP Port' for each and specifying the address of the target printer, but it always fails, seemingly because the printer cannot be contacted.
I have requested that port 9100 be opened on the remote firewall, but that has made no difference (this is the port that Windows states it will use for the printing). I cannot ping the printers, as ping traffic is denied by my client's firewall.
Has anyone else come across the same problems when trying to configure remote printers? Did you have to configure something special on the firewalls to allow printing to occur?
