Re: lpd protocol

If you're really serious about writing an lpr or lpd, the source code for
FreeBSD's versions is online here:
http://www.FreeBSD.org/cgi/cvsweb.cgi/src/usr.sbin/lpr/

FreeBSD is directly derived from the original Berkeley source that lpr/lpd
was developed for, so the source code would be the "ultimate
documentation". :)

For communicating with an AS/400, however, the tn5250e protocol would
probably work better.  You can see RFC1205 and RFC2877 for information on
this -- however, since it involves parsing the 5250 datastream, and then
parsing SCS data, its about as much fun as hitting yourself over the head
with a shovel.

The Linux tn5250 project has a daemon that will receive print requests and
pipe them to a program of your choice, which might be ideal if you're
running Linux, FreeBSD or similar flavor of Unix.  

You can grab a copy of that over here:
    http://cvs.cleveland.lug.net/module.pl?module=tn5250

Good luck.
