[9fans] Getting printing to work over ethernet

[Jonas Amoson]

Hello!

I am trying to print from my Plan 9 computer
to my networked laser printer. It (a HP 2015n)
speaks Postscript  and is connected to the same
router as my computer. The printer has got the
IP 192.168.1.101 from the router, as it uses NAT.

I have tried to add different entries to the file
/sys/lib/lp/devices inspired by the examples in
the same file. Here are two of my best tries:

hplaser   mydesk 192.168.1.101 192.168.1.101
   - post+600dpi generic generic generic generic tcppost
hplaser2  mydesk 192.168.1.101 tcp!192.168.1.101!9100
   81920 post+600dpi generic generic generic generic tcppost

Then I try to print something, 'lp -d hplaser tst.ps'
I get the following errors:

Aug 22 18:48:23 write error during pass, 11356 bytes remaining
Aug 22 18:48:23 failed to send 11356 bytes

It works well to 'ip/ping' the printer, and it also
works to print from my Linux computer, connected
to the same router.

Any ideas of what goes wrong? Anything I have to
do besides adding an entry in the devices-file?

Best,
Jonas

we use something like this

printer somewhere minooka.coraid.com tcp!printer!9100 81920 post2+1200dpi+duplex
	generic generic generic generic tcppost FIFO

i think you may need a FIFO after tcppost.

The final `FIFO' in the scheduler column of /sys/lib/lp/devices
has been optional for a while.  Everybody uses FIFO now, so it's
the default.

is there a man page for those of us who are not
quite following along with the format?

It's not documented in a manual page, I think you have to read
/sys/doc/lp.*, section 4.

I have not progressed any further in getting lp(1)
to print to my networked printer. But by playing
around, I found a work-around that solves my problem
for the moment:

cat myfile.ps | telnet tcp!192.168.1.101!9100

For what it's worth, I have networked PS printer (Samsung CLP550) and these
settings in my /sys/lib/lp/devices work (I have no real understanding of
what the lpd* things do behind the scenes, though):

clp550    robbys-room    clp550n    raw    -    post2+1200dpi+nohead
generic    lpdspool    lpd    -    -    FIFO
clp550d    robbys-room    clp550n    raw    -
post2+1200dpi+duplex+nohead    generic    lpdspool    lpd    -    -    FIFO


Note that I also have the printer as an entry in my /lib/ndb/local, so
clp550n is 192.168.0.200 or something.

See also /sys/doc/lp.ps

OK. that explains why adding FIFO didn't make
any difference. But now I know that I have done
whatever you are supposed to do to make it work,
so I will try to track down why there are errors.

Wanted to know if there was something else to
configure or run for the magic to work. The only
relevant documentation I've found on the subject
is lp(1) and lp(8), and /sys/src/cmd/lp/.
