The first thing to check is the LaserWriter setup. UNIX administrators know how to set up the /etc/printcap file, but they assume the printer does not need configuration for text.
The LaserWriter 16/600 PS defaults to PostScript as the TCP/IP mode, however, PostScript cannot handle text files. PCL5 handles text files, so the TCP/IP mode should to be changed to PCL5. If PostScript is also expected from this printer, choose AutoSelect. Here are the instructions:
Step 1
Move the configuration switch located above the Parallel port on the back of the printer to the up position.
Step 2
Launch the Apple Printer Utility.
Step 3
Open the Communication Configuration category.
Step 4
Open the Up Switch Position category (Custom)
Step 5
Set the TCP/IP mode to AutoSelect
Step 6
Press the Send button
Also check the /etc/printcap file. Follow the example on page 125 of the "Apple LaserWriter 16/600 PS: Setting Up, Connecting, and Using Your Printer" manual that came with your LaserWriter 16/600 PS. More specifically, check the type to which "rp" is set. If "rp=text" and the printer is not working correctly, try "rp=raw", or visa-versa.
More in-depth information on setting up the /etc/printcap file can be found in the Tech Info Library article "LaserWriter 16/600 PS & Sun Solaris Through TCP/IP".
