[9fans] Communication with a Network Printer

["Mark C. Otto" <Mark_Otto@FWS.Gov>]

I am trying to set up printing on two network printers, an HP3si and a HP4000. 
Both have jet direct cards.  The handshaking with the printer does not seem to
work:

lp -d3si file_to_print
Dec 19 11:02:44 failed to receive ACK, received <0x6c>
Dec 19 11:02:44 failed to receive ACK before sending data

The message seems to be coming from lpsend.  I could use some pointers on where
to look next.

I can telnet to the printers and get the tcp/ip information on the jet direct
card and call on the printer port

telnet tcp!3si!515 # or !9100
connected to tcp!3si.irm.r9.fws.gov!9100 on /net/tcp/2

device_name	loc	dest_host	phys_dev_name	speed	class	def_proc	spooler	stat	kill
daemon	sched
3si	Hen-Conf	bfbooby	tcp!3si!9100	8192	post+300dpi+duplex+nohead	generic	generic
generic	generic	tcppost	FIFO
4k	Hen-Conf	bfbooby	tcp!4k!9100	8192	post/2+600dpi	generic	generic	generic
generic	tcppost	FIFO

I made directories for each printer:

LPLIB/prob/3si and LPLIB/prob/4k

and made them world writable.  After running the commands, nothing was in them.
