[9front] Printing configuration

[9front] Printing configuration

[chris]

Hello all,

I'm trying to setup printing on my 9front desktop.  I have a Canon
TS6300 at home, which I would like to directly send print requests
from the desktop via USB and preferable wireless network request.

I'm having a hard time setting up my /sys/lib/lp/devices config even
after reading /sys/doc/lp.ps and lp(1) and was hoping for someone with
perhaps a similar requirement and a working config to share.

My current two device setups are probably total bogus, but here we go:

; tail -n2 /sys/lib/lp/devices 
homeTS6300wifi	- 192.168.178.82 tcp!192.168.178.82!515	- post+nohead generic generic generic - tcppost -
homeTS6300usb	- /dev/usb/ep13.1/data - - post+nohead generic nospool - - - -
;

I manage to get following error with the wifi printer:

; lp -dhomeTS6300wifi test.ps 
Jun  5 17:15:15 failed to receive ACK, received <0x1> instead
Jun  5 17:15:15 failed to receive ACK before sending data
;

The printer itself works of course on other operating systems with
standard manufacturer documentation.
515 seems to be the proper port and gives something back when using
telnet.

I assume that the printer supports postscript, but I didn't seem to
find a explicit spec mentioning it.  I might be wrong assuming that.
Although plain text alone would already be a blessing.

The wifi printer seems to send something apparently with lpd settings
refering to the log, but nothing really happens:

; tail -n2 /sys/lib/lp/devices 
homeTS6300wifi	- 192.168.178.82 tcp!192.168.178.82!515	- post+nohead generic lpdspool lpstat - tcppost -
homeTS6300usb	- /dev/usb/ep13.1/data - - post+nohead generic nospool - - - -
; cat /sys/lib/lp/log/homeTS6300wifi.st 
connecting to tcp!192.168.178.82!515
 trying from port 721...connected
: 69.13% sent
: 100.00% sent
11850 bytes sent, status: waiting for end of job

I tried lpd settings because my printer test page (printed out on
through other device) mentions LPD as enabled.  Other settings
mentioned are:

- WSD Printing => enabled
- RAW Printing => enabled
- Bonjour => enabled
- LLMNR => enabled
- SNMP = enabled
- PictBridge Commun. => enable

I hope I provided enough information for someone to perhaps see a weak
point or general advice for my configuration.  Refering me to
additional resources could also help.

At a minimum I would assume you would have to bring usb/print along to nusb.

Howto: https://inbox.vuxu.org/9fans/aefe5050714a813fb41e09b511643954@rei2.9hal/

Anyone else wanting to do this can use a Raspberry Pi to test it:

Hm I didn't get anything that helps out of that thread.

You might have seen that I already tried using a /dev/usb/ep* device
in my config, but I didn't manage do understand which of the multiple
dedicated files for the printer I should use or if these are even
meant to be directly used by me as a user.

The sample device configs show a /dev/lpt1data device, I would assume that I
might have to configure usbd properly to create a useable high level
device like that?

PS: Sorry for the late response.  Barely got time for a computer the
last days.  Trying my best to read more into the usb man as soon as
I can.

I don't know anything about printing on Plan 9. I did say assume. But yeah,

is basically my experience with USB on Plan 9, too.

Port 515 is for the LPD protocol. By using tcppost, you're trying
to send it RAW/JetDirect data (which is usually handled on port
9100).

And drop the last "-" on each line (the sched field) of your devices
file. You don't need it unless you know you need it.

Cheers,
  Anthony
