For some time MacOS Laserwriter 8 has had the ability to create 
"Desktop Printers" which point at an lpr print server.  This works 
fine with HP JetDirect print servers:  You give it the IP address and 
specify the "RAW" queue and you're done.

So I set up a RAW queue on a PC running NetBSD lpd to /dev/lpa0 and 
it doesn't quite work.  The Mac job sends all its data just fine, and 
then gives me an error at the end.  Nothing seems to happen on the 
PC.  The printer activity light doesn't blink (it's an HP 1200) and 
lpq -PRAW shows nothing afterward.

The printer seems to work fine with enscript -PRAW on the NetBSD 
side, but the activity light continues to blink for some time after 
the job is done.  There doesn't seem to be any way to lock the 
printer into Postscript-only mode, but I'm still looking at the 
documentation since I can't print it.  ;-)

I remember seeing some comments about the HP interfaces not closing 
out Appletalk print jobs properly at the end.  Don't know if that 
rings any bells for people.

So, anybody got any ideas?  Thanks for any help.
