    Also, when posting info/data you need to specify the computer it came from.

    The client FWs themselves should not be relevant, only the server FW might block. You may need to describe exactly what you're doing on the client machines when you're stop/restarting your FWs.

    You can also install hplip even if you're not using HP printers (and definitely should if an HP printer) to visually detect active printer connections. You may be able to verify as I originally speculated that the problem may not be a FW issue.

    I had a second look at the firewall log he posted, which is quite
    difficult to read here, and he is getting packets rejected on port 631.

    1: Opening TCP-Services for a specific machine (in YAST/firewall: CustomRules)

    4: Stoping an Starting firewall

I have noticed that over time the firewall of all comps close down the 631 port, which had been opened to all machine in order to allow them to print. Shutting down and switching on again the firewalls of the server comp and client comp reopens the port and the printing is available again. Is there a configuration of firewall that will prevent of closing of a port if it is not in use for a while ?
    Thanks
