Sophos XG Firewalls Printer Delay or Not Printing at all

Keith Wolbert

We have serval offices (Well over 30 locations) that experience printing issues when going through our Sophos XG (115/125) Firewalls. 

When printing, the printer can take up to 5 to 30 minutes before it will print. If we remove the Sophos Devices, printing returns to normal, less then a second to print.

We noticed It mostly effect the Epson TM- Receipt printers on Port 9100 but other printers are reported to experience problems from time to time.

The communication for which the print job is received can very, it's not specific to the media, such as standard ethernet, VPN, MPLS.

Firmware is up to date and all advance features is turned off. Doing a packet captures show the print job hitting the correct firewall rules with not type of inspection or

filtering turned on. If we bypass or even replace the firewall with an ASA, Sonic Wall, FortiGate then the issues no longer happens.

Any advise ??? Thanks, Keith

    You probably have an IPS rule, or maybe DPI inspection rule, affecting it.  Have you tried starting a support case at support sophos.com?

    I have made sure all those features were turned off! I also tried in transparent mode vs routed mode. Nothing helps. I have worked with sophos  support and to be completely honestly it has been a complete waste of time. We went round robin for at least 6 month with the same response

    "Your remote access expired can you please reenable it on the devices" Or

    "You will have a response by xxx date which then gets passed to another technician."
