Subject: HP LJ4m pap lossage

We've been having some problems with an HP LaserJet 4m on LocalTalk which
we recently hooked up. We're spooling from a SPARC IPC running SunOS
4.1.3 and netatalk-1.2.1, and using a GatorBox to gateway from our Phase
I EtherTalk to LocalTalk, which is what the printer is on. The printer
works fine with Macs (on ethernet), and our pap works fine with an Apple
LaserWriter II and various TI printers. It also works fine with short
files to the HPLJ. I grabbed the latest bin/pap sources from 1.3b2 and
built with -DEBUG -DPRAGMATIC (although I didn't build the 3b2 libatalk).
A short file (enscript /etc/motd) generates the following output:
Trying 11110.194:128 ...

Connection closed.
A longer file (still one page, dvips output), never closes the connection,
although it does print the whole file:

Curiously, the new pap doesn't notice when I do a pushbutton-reset on
the printer; the old pap disconnected at that point (saying "connection
unexpectedly closed; send file failed"). For the moment we're using
the old pap, and doing a by-hand printer reset after every job spooled
from Unix.
Any insights, or pointers to new pap sources, would be much appreciated!
