Right now the only laser printer we have is a LaserWriter Select which is set up with my PowerBook 3400c (running Mac OS 8.6). Appletalk is "on" on the 3400c, but aimed at the serial port for the printer. I can connect to any of my Mac OS X based systems (10.2.x, 10.3.x and 10.4.x) by using the other computer's IP address in the "connect to server" dialog from the Chooser after selecting AppleShare. My wife has a "Print Me" folder on her desktop on her PowerBook (running 10.4.11) where she saves PDFs for me to print later from my 3400c.
My network also usually enjoys an additional amount of connectivity (specially between my Mac OS X and Mac OS 8/9 systems and my Rhapsody systems) thanks to Xinet's KAShare running on an SGI workstation. Sadly my Indy is down (due to be replaced by an Indigo 2 IMPACT), and I haven't as yet gotten one of my old IRIS Indigos up and running just yet to fill the void (which means I use FTP between my Rhapsody systems and the rest of the network currently). Of course I still use RBrowser for FTP stuff so it doesn't seem all that awkward.
