The wireshark investigations were key, but you drew the wrong conclusion - that there was something wrong with the printer. You can't always blame the symptom (the printer here) as the problem.

It was another device in our network after all. Our Fox Davo phone switch decided to allocate two additional IP addresses to itself, without asking. One of them conflicted with the printer. It's a bit odd that this printer has problems with it, whereas the old Xerox 232 didn't. The only theory I have at the moment, is that this new machine must be faster in responding to ARP requests than the phone switch, whereas the old printer was slower. If the printer informs the clients that it has IP address x after the phone switch does, it may be enough to let the clients have an accurate ARP table. I found out what the problem was.
