This is very interesting. What I was getting is:
1. Job prints fine,
2. Long pause,
3. Postscript error
with no blank page. If I use ps_eoj_at_start@, I get:
1. Job prints fine,
2. *Really* long pause (~10 minutes I think)
3. Job prints again

I grabbed ifhp 3.4.1 and used shutdown_appsocket and everything now
works fine. BUT, since I didn't have this problem at all with ifhp
running on a NetBSD 1.4.1 machine, I wonder is the problem really the
printer, or is it the difference between the BSD and Solaris TCP/IP
stacks?
By the way, were you printing successfully from Unix clients while the
Windows clients were having problems? That seems to be a *really*
wierd thing to be fixed by shutdown_appsocket.
Everything is working now with shutdown_appsocket, I'm just wondering
why it broke in the first place. For instance, the Solaris box in
question has YASSP installed, which does some fairly complicated
network tuning at boot time.
