I'm not sure if they're too tall for your needs, but the LaserJet 4M and the 4M Plus were workhorses in their day and they use standard 72 pin SIMMs for memory expansion.
I have a nice little LaserJet 2100NT which I'm very happy with. It comes standard with LocalTalk and has a PIO slot (or whatever HP was calling it at that time) for another network card, such as fast ethernet.
The fast ethernet card was well under $20 last time I looked. Of course, if you get a real 2100nt it already has the card. The 2100 nt is a 2100 with the Postscript SIMM (or is it a DIMM) and an ethernet card in the PIO slot.
However, laser printers are so cheap to buy new now days... The problem is you'll likely never find one with LocalTalk/AppleTalk support. You can overcome the lack of LocalTalk support with a LocalTalk/Ethernet bridge such as the AsanteTalk or the MicroAsantePrint, but if the printer doesn't speak AppleTalk it won't matter, unless you can get your old computer to output TCP/IP when it prints.
Two years ago I was shopping for a color laser printer. For some reason, that holiday season there were several (well, three) models for $200 - $300 shipped and each included postscript and ethernet built in. I think the $300 printer also had a duplexer included. I haven't seen deals that good on color laser printers since then. However, of the three (Xerox Phaser 6180, Brother mumble, Kyocera EcoPro 170N), only the Kyocera included AppleTalk as a supported communications protocol. The others would have required my old Macs to send their postscript in TCP/IP protocol. So I bought the Kyocera for $200 shipped. A steal.
Unfortunately, Kyocera seems to have discontinued their economical consumer/SOHO printer line. At least toner is still available, although I haven't needed any yet.
