Before we bought Transcript (for the conversion routines), we set up a
print que to print postscript files directly to our LWII/NTX.  The single
most useful thing I did when setting it up was to connect a spare VT220
(any asynch terminal will do) in parallel with the printer's SendData
pins.  This allowed all printer errors to be easily visible -- which made
solving problems like "It blinked, but it didn't print" much easier.

The cable looks like this:

  Printer		        	VT220
	   2 ----------+-------------- 3
	   7 ------------+------------ 7
           3 --------+ | |            
		     | | | 
		     | | | 
		     | | | 
		     | | | 
		     | | | 
		     | | | 
		     2 3 7

This is probably a flagrant violation of the RS-232 spec, but it has
worked for several years on a couple of different Apple Laserwriter
printers.
