Issue: A non-domain PC(PC-A) can no longer print to a networked printer.
When I print from a domain PC(PC-B) it works because the job comes from the Print Server. However I couldn't ping the printer.
So I checked the firewall and it is dropping ICMP Replies because there is no matching Request. So for some reason the ICMP Request is going through the switches directly to the printer but the Reply goes through the firewall and gets dropped.

We're in the middle of a switch refresh so the infrastructure is rather funky.
