Print Server

[Andy Liu]

@Zheng-Han Thanks I managed to get it to work! Awesome. Below will detail the steps I took.

1. Change root Password:
   passwd

2. Enable Default LEDE repo:
   vi /etc/opkg/distfeeds.conf
   src/gz reboot_core http://downloads.lede-project.org/snapshots/targets/ramips/mt7688/packages
   src/gz reboot_base http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/base
   src/gz reboot_packages http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/packages

3. Update USB-Essentials
   opkg update
   opkg install kmod-usb2 --force-depends

4. Enable TCP Port 9100
   vi /etc/config/firewall
   #Allow attached network printer
   config rule
   option src 'apcli0'
   option proto 'tcp'
   option dest_port '9100'
   option target 'ACCEPT'

5. Update USB Printer Driver
   opkg [code]upgrade kmod-usb-printer --force-depends

6. Plug In Printer and Check if is Connected
   Look for /dev/usb/lp0

7. Install p910nd daemon
   opkg install p910nd

8. Configure daemon
   vi /etc/config/p910nd
   config p910nd
   option device /dev/usb/lp0
   option port 0
   option bidirectional 1
   option enabled 1

9. Restart daemon
   /etc/init.d/p910nd restart

Would be nice if this Tutorial finds the way in to the manual or wiki.
@Andy-Liu if you have github you could propose as pull request.

@Andy-Liu was it an O, O2 or 2+?

Can you print from an iPhone or Android using this setup?

[Andy Liu]

@Luciano-S I don't have a github or anything. Maybe you can help set it up?
@Costas-Costas I was using a O2 but i dont see why it will not work for the rest of the series.
@James-Harding I didn't really meant it for printing from a phone. But it is a good idea. Will look into it when I have more time. Work for me this month is really pilling up.

@Luciano-S. okayz! will look into it when I am free. Thanks!

Hey there,

thanks for the good explanation on how to run p910nd on an Omega!
I have the Omega2+, and I am trying to get my printer (Samsung ml-2850d) running with p910nd. I have a USB cable soldered directly to the Omega2 as power supply with a 3.3V voltage regulator inbetween. Then I connect the printer via USB directly to the D- and D+ pins of the Omega2 board (pin out).
The problem is, that I do not see my printer under /dev/usb/. I am not sure whether the printer needs the gnd and v+ connection from the board to be recognized or if it's not supported?

Cheers
Nils

[Andy Liu]

@Nils-Flaschel I am not sure as I have not done with physical wiring to the board. I am using a dock currently. Will be looking to remove the dock when I have time to figure everything out. You could try providing a 5V to V+ and ground to V-.

Hi!

When I try to

 opkg install p910nd

it says :

Unknown package 'p910nd'.


Collected errors:

 * opkg_install_cmd: Cannot install package p910nd.

Why is this like that. I would like to build a print server with my Omega 2. My Router runs DD-WRT

Hello,

i tried to get the printer server online but I always get the error: usblp module was not found while installing the kmod-usb2.
Has the kernel been changed? I thought it should have the usb printer support activated...

(I'm using a Omega2 for this project)

[Matthias Nowak]

Any way we can get it to work with other printers too? or maybe compile cups for the omega?

@Andy-Liu said in Print Server:

opkg install kmod-usb2 --force-depends

Hi, I tried to follow your steps but getting stuck at the installation of kmod-usb2 and kmod-usb-printer. I am using Omega2+.

The same error message:
pkg_run_script: package "kmod-usb-printer" postinst script returned status 255.
opkg_configure: kmod-usb-printer.postinst returned 255.

Any suggestions?

[Malachi Burke]

/dev/usb/lp0 won't show up for me.

kmod-usb2 and kmod-usb-printer are installed

Unplugging/plugging printer cable yields:

[ 1441.830049] usb 2-1: USB disconnect, device number 4
[ 1446.755533] usb 2-1: new full-speed USB device number 5 using ohci-platform

Was working until I rebooted the device. Any clues?

EDIT: OK, this was incredibly nasty, but this is how you fix it:

wget these two:

http://repo.onion.io/omega2/packages/core/kmod-usb2_4.4.46-1_mipsel_24kc.ipk
http://repo.onion.io/omega2/packages/core/kmod-usb-printer_4.4.46-1_mipsel_24kc.ipk

Then opkg install both of them by filename, using the --force-depends option

It seems the LEDE repo feeds, while an interesting idea, might be too much of a moving target. Even the .ipks downloaded from the links above are not an exact match for the kernel, but on my system close enough to make things work.
