OK, the first document, TN17555 discusses the dip switch on the back of the 16/600 printer. Up or down position changes how the printer ports interact. Set it to the DOWN position.
The second article, TN 50128 has a list of manuals for Apple Laserwriters, I just downloaded the one for the 16/600. On page 31 of the manual, it starts talking about setting the printer options. it mentions the switch and using the Apple Printer Utility to set options for the printer.
For ethernet connectivity, you need an Apple AAUI ethernet tranceiver. You can find these around various places, I sell them if you have trouble finding one, $25 for the Farallon Ethermac AAUI tranceiver. This converts the 15-pin 'Centronics' connector to a standard 10Base-T twisted pair cable.
Hmmm. Does the belkin Wireless router pass Appletalk??? Important question. Look in its manual and find out. If it does, you can just use AppleTalk and be done with it. Connect them together, open Printer Setup Utility in Panther and setup a new AppleTalk printer. You're done. Have a nice day
You might get better performance and would avoid network chattiness of Appletalk if you use IP. The choice is yours
If the router doesn't pass AppleTalk, you'll have to use IP. First connect the printer's ethernet cable directly to your PBook. Wait, do you have an ethernet hub? Does the belkin router? Connect the PBook and Printer cable to a hub, otherwise you will need a ethernet crossover cable to connect them directly to each other.
Now get your hands on a copy of the Apple Printer Utility. it is a Classic App. Launch that and your printer should show up. Open it and in the settings list, there should be something for IP address and mask. I don't have one of these printers here, so I don't know exactly what the menus look like. You need to assign a fixed IP address and subnet mask to the printer. Open System Preferences in Panther, and check your network Pane for the current IP, network mask, and router address. they are probably 192.168.1.2, 255.255.255.0, 192.168.1.254 or something like that. They could be in the 10.1.1.x range.
This is getting long and involved.
Why don't you get back to me when you get to this point and I'll explain what you need to do next. You need to tell your router NOT to assign the same IP address to computers in your network than you are about to assign the printer.
