[9fans] HP Laserjet over JetDirect

[9fans] HP Laserjet over JetDirect

[john]

I'm trying to print to a Laserjet 4700dtn from Plan 9.
I can print to it from Linux using CUPS connecting to
socket://<IP>:9100
Does anyone have one of these or something similar?
My line in /sys/lib/lp/devices looks like this:
hpson2		-		plan9		tcp!hpson!9100		81920	post+600dpi			generic		generic		generic		generic		tcppost		FIFO

where plan9 is the cpu server and hpson is the printer. There
are probably problems with this, so if you have suggestions
please let me know.

that looks correct to me.  this is what we use for a 4400dtn (i think)

printer		whatever		minooka.coraid.com	tcp!pr2!9100		81920	post2+600dpi+duplex	generic		generic		generic		generic		tcppost		FIFO

although it's really odd that we are using minooka.coraid.com and not minooka
as the printer host.

we have a similar hp printer that does not work with tcppost.  i think the answer
is that tcppost needs a rewrite, but that fell off my radar screen.  i believe the
problem is that that silly baud rate (last i checked, tcp has flow control).  it's
so slow that i was wondering if printers weren't getting bored and hanging up.
