Two printers on the network - hp p1102 and p1102s. How can their conflict be resolved?

Question

Network administration

The fact is that the P1102s works stably both directly via USB and connects to any computer via the network. And P1102 works only directly via USB, when connected over the network it gives errors:
1) No printer was found
2) The specified port does not exist
Sometimes it is possible to connect by pressing Enter, ignoring errors, but very rarely.
I have a feeling that these two printers are in conflict with each other, although they use two different ports.
P1102s is shared via Windows XP, P1102 is shared via Windows 7, server is Windows Server 2012 r2.
Whether it is possible to solve this problem somehow?

Answer 1

The name of the computer from which P1102 was shared was in Russian. I wrote the name in English - the problem disappeared. Might be useful to someone...
