The IRIS is SYS V with BSD enhancements...enough said.  Many of our customers
LIKE the SYS V lp system--It has much more flexibility than the BSD system as
far as multiple printers on a single queue point, but alas, BSD users want
their printcaps.

The lpr source code I sent out to people who asked me for it was to allow
SYS V users (this was originally written for AIX) to print to BSD-based 
printservers. Since I cannot distribute any of OUR source code, this seemed
like an opportune time to send the lpr.src to others who might not know such a
solution was available.  This would allow a simple request to be generated 
for the lpd listening on the other end.  Another way to do it is to setup a 
printer using mknetpr, and then hack around and make the script do a "rsh <> 
lpr" instead of rsh <> lp".  A trivial issue.  I could say the same about BSD 
being a pain to implement...Please tell me how you can get a Sun to print to 
a printer on a SYS V machine...? (Other than using "cat <> | rsh  IRIS lp")

Again, the issues here is not which is better--we will see what happens 
in ATT 4.0. 

In answer to your questions:

1) lpr really shouldn't be on the 3000's as far as I'm concerned--it's not on
the 4D's, unless the owner actually ported the real BSD-lp*.

2) BSD-lpr uses /etc/printcap, whereas the lp on the 3000 and 4D machines 
use the interface files.

3) Since you posted a response to a question that we didn't have the pleasure
of seeing, I can't touch this one.  Why don't you try including a quick blurb 
about the question so the rest of us without the original posting can see what
you're talking about.

4) "The best OS is BSD with SYS V enhancements".  I'm not too sure about this.

5) In response to your other posting, "what does a psuedo lpr/lpq do?
Well, I guess you already modified your printer scripts to do it for you.  This
is an actual port of a portion of the BSD-lpr code.  I guess you don't need it.
Doesn't sound like you want it either.

Hope this explains the issues at hand for you and other users--sure has been
popular--I have gotten at least 20 requests so far. I'm sure the printer tool
folks within SGI are looking at new ways to make things like this available
in the future--not for me to decide, though.
