P910nd problem

alex_lynx · November 14, 2019, 11:56am

The LAN OpenWrt IP is 192.168.0.2, as I understand, the printer IP is the same. PC is connected to the LAN. SaneTwain is configured to 192.168.0.2:6566 and works well.

By the way, if I remove p910nd.prn1.bind='192.168.0.2' the port listening is looking like
tcp 0 0 0.0.0.0:9100 0.0.0.0:* LISTEN 1706/p9100d
but still don't work

Now I have TP-Link wr842nd, Chaos Calmer 15.05 and Canon 2900 printer. But result is pretty the same Where am I wrong???

bolvan · December 26, 2019, 2:12pm

I see 2 possible causes

try bidirectional 0
its possible your printer needs firmware after each power on. This is the case for my HP P1005, not sure about yours. I had to write manual scripts to satisfy the device

alex_lynx · January 1, 2020, 4:40pm

Thank you!

already tried for both printers
I know about the firmware uploading for printers like 1005, but I could not find the firmware for HP 1120 and for canon 2900. Thats why I think I do not need to do it.

Hi @bolvan,

I have the same printer (HP Laserjet P1005), a router Tp-Link TLWR 1043ND with Openwrt 19.07.1 and p910nd package...

I configured my router to use extraroot and I use a USB hub since that router has only one USB port.

Using the command "lsusb -v", I see that both the printer, the USB stick and the USB hub are detected correctly.

Using the command "dmesg", I notice that the kernel correctly detected the printer too ...

I created the script to load the firmware to the printer, but I can't test whether it was loaded correctly or not, however, if I enter the command that loads the firmware on the command line through ssh, I watch the printer start up correctly.

Honestly, I don't know where I might be going wrong, so I come here to ask that if possible, you can provide a step-by-step tutorial for setting up the HP Laserjet P1005 on Openwrt using the p910nd as a print server.

Thank you very much in advance!

Thanks for your reply @bolvan...

I followed your tutorial step by step and got everything working correctly during the tests, but I still can't print and honestly, I don't know where I could be wrong ...

I have some doubts:

Does the script "20-hplj1020" need to be executable? (chamod a + x)? In new installations, p910nd creates the folder "/etc/hotplug.d/usbmisc" where I put the script inside and it also didn't work ...
After finishing the settings, I restarted the p910nd, having no effect, restarted the router ...
The settings on my Windows station are like this: I believe that there is no secret here ...

2020-03-16_20h11_06474×510 10.2 KB

As you can see, I disabled "bidirectional" printing support in Windows dirver ...
Finally, my "printserver", I configured with IP 192.168.1.2 and because this router is an "AP", I disabled the firewall. My main router has IP 192.168.1.1 and it has an active firewall, with the following rule:

config rule
        option name 'Allow PrintServer on 192.168.1.2'
        option src 'lan'
        option dest_port '9100'
        option target 'ACCEPT'
        list dest_ip '192.168.1.2'
        list proto 'tcp'
        list proto 'udp'

I really don't know where I'm going wrong. If you can help me within your means, I am grateful!

In windows print dialog select your HP printer, check "print to file". Save something.prn
Copy it to openwrt
After applying firmware do cat something.prn >/dev/usb/lp0
does it print ?

files in /etc/hotplug.d do not have to be executable

topsbr · March 17, 2020, 3:44pm

Ok, I created the .prn file and copied it to the router ... no problem!

I loaded the firmware manually with the command "cat /lib/firmware/hp/sihpP1005.dl> /dev/usb/lp0" where the red led flashed and the printer mechanism was activated ...

I tried to send the .prn file for printing using the command "cat hp.prn> /dev/usb/lp0" and nothing happens ...

Some information:

I'm trying to use a 1443ND for this function, configured as dumb AP...
I am using a USB Hub powered by a good 5Volts x 2.5Amp power supply...
Use extroot with a good USB Stick too ...
Openwrt 19.07.2, firewall disabled for testing ...

I'm starting to think it might be something on the router, too weird ...

bolvan · March 17, 2020, 4:09pm

prn blob is what normally being sent to the printer's port
print to file function saves it to a file instead of queuing to the spooler
printer should print it
If it does not and it works normally in windows then it could be bad firmware
md5sum of my firmware that works is
87169d2606a44e186a4ed5d142da0c89 sihpP1005.dl
if you own another file I can post mine

prn file for P1005 should start with XQX preamble. check it in hexdump or hexedit

But I can't tell you if it's right. I used the command "hexdump hp.prn" to get it.

bolvan · March 17, 2020, 6:34pm

"hexdump -C" is the right thing
from what you posted I can state

firmware is different from mine.
Here is my file : https://www.sendspace.com/file/tj16e6
prn does not look correct.What windows printer driver do you use ?
P1005 is xqx printer.

1 - Thanks for your file, I will test im my router...
2 - I didn't quite understand your question, but I'm using the driver with the versions below in Windows 10:

bolvan · March 17, 2020, 7:06pm

I use the same driver and it produces XQX output.
May be you used some advanced software like ms word with custom print dialog, not standard one, and selected custom "print to file function" ?
Try with notepad. It calls standard windows print dialog. Ensure correct printer is selected

Your file is in ZIMFprint format. Its different wire protocol

topsbr · March 17, 2020, 7:24pm

I retry the test using notepad and printing file...

Again, the ZIMF print format is present...

I honestly don't know how to change that ...

bolvan · March 17, 2020, 7:40pm

In printer preferences check Advanced->Print processor dialog

topsbr · March 17, 2020, 8:35pm

Did not work...

Even changing the requested configuration, generating the file with the identification of XQX and restarting the router ... When sending an impression, nothing happens.

I can't set the print processor to "IMF" by default. I define it and it always returns to "RAW" ,,,

That's enough for today, I'm tired, but tomorrow I'll try again.

Thanks for the help @bolvan

topsbr · March 18, 2020, 11:12am

Good morning everyone! The "saga" continues ...

I redid the configuration of my 1043ND router using version 18.06.8 for testing ...
I reinstalled the HP driver on my desktop and now I was able to correctly set the print processor to "XQX" ...

I remade the script exactly the same way and with the same name that @bolvan had posted, performed the test using the command "cat", the printer starts normally, but I still can't print.

In the desktop driver, I configure this for appoint to the ip 192.168.0.2 (router ip / printserver), config for RAW mode and port 9100 ... Do not print!

I restarted the router and nothing ... I believe that for some problem, the script does not start on the router or whatever else may be happening ... How to test to see that starts or no??

I followed the tutorial step-by-step, everything works, but it doesn't print.

I removed the USB hub and connect my print directly on the router... I remove extroot configs too.

Ah, I disabled the firewall on the print-server and the main router, as well as the Windows firewall too ...

Could someone give me the command of tcpdump to monitor the router if any request is coming from the Windows machine?

I haven't given up yet lol

bolvan · March 18, 2020, 12:31pm

If cat firmware; cat xqx doesnt work then it won't work at all
All what p910nd does is netcat-ting socket input to specified lp device
it receives prn file and pipes it to lp

does your printer work if connected to a PC ?

tcpdump -ni br-lan tcp port 9100
but you can also run wireshark in windows

note that scripts must be unix EOL (0A instead of OD0A)
