[9fans] printing over usb

[9fans] printing over usb

[James Chapman]

Hi,

I would like to use my hp laserjet 1300 postscript printer with plan9.
I'm running plan9 under vmware fusion on a macbook and the printer is
connected via usb.

I checked that the printer is visible:

term% usb/probe
ep1.0 roothub csp 0x000009 ports 2 uhci
ep2.0 roothub csp 0x000009 ports 6 ehci
ep3.0 hub csp 0x000009 ports 7 none <nil> uhci
ep4.0 printer csp 0x030107 csp 0x010107 vid 0x03f0 did 0x1017
Hewlett-Packard 'hp LaserJet 1300' uhci

I added the following line to /sys/lib/lp/devices:

laserjet1300	- - /dev/usb/ep4.0/data - post+nohead generic nospool - - - -

Then I tried to print something:

term% lp -dlaserjet1300 /sys/doc/utf.ps
cat: write error copying <stdin>: request timed out

Can somebody tell me what I'm doing wrong?

Best wishes,

James Chapman

Ep4.0 does not look like the place to send data. It's probably the control ep.
for the printer. IIRC, the driver adds a file named lp something, but I'm not
sure. Try to look at /dev to see if there's a file there. Otherwise it could be
something like ep4.1

term% du -ah /dev | grep lp

yields only this:

1k	/dev/lpt1dlr
1k	/dev/lpt1psr
0	/dev/lpt1pcr
0	/dev/lpt1data

I don't seem to have an ep4.1:

term% usb/probe
ep1.0 roothub csp 0x000009 ports 2 uhci
ep2.0 roothub csp 0x000009 ports 6 ehci
ep3.0 hub csp 0x000009 ports 7 none <nil> uhci
ep4.0 printer csp 0x030107 csp 0x010107 vid 0x03f0 did 0x1017
Hewlett-Packard 'hp LaserJet 1300' uhci

Hi,

I 'solved' the problem by attaching the printer to my apple airport
express. Now I can print from plan9 using this neat trick I found
whilst digging in 9fans:

term% cat test.ps | telnet tcp!express.lan!9100
connected to tcp!express.lan!9100 on /net/tcp/2

I'd still like to be able to directly connect with usb. I will try
with native plan 9 instead of under vmware fusion and also try a
different printer to see if I get different results.

Is there some extra extra debugging I can enable to see what's going
on with the usb devices?

Best wishes,

James Chapman

you can also print through lp(1) in this way.  i believe
the JetDirect example in /sys/lib/lp/devices is the right
template.

I made a post about this not too long ago.

However, the problem is in the fact that
with a port listening for data to print directly,
anything and everything that comes in, gets
printed. Beware of portscanners, etc..

A better method would be to setup a proper
LPR port (lpdaemon) such as in
/rc/bin/service/tcp515 - however, I could not
get this to ever work, because I need the
data to be processed by hpijs, and something
goes wrong between the data coming in and
being sent to lp via lpdaemon. I don't know
what (ideas? see my previous post about this).


Best,
ak

Yes. You might start with -d flags to usbd or issuing a debug ctl
(see the man page) to see what's the error.
