Problems Runing Cups on Synology as a docker

[hemant5400z]

Hi Olbat (and all),

I'm trying to run Cups in a docker and the launch goed fine, setp also works and i can see the printer on my Iphone. When I launch a print job I can select the printer (using Gutenberg driver HP3800dn).

The problems comes when actually printing, it somtimes start printing but stops after one page or does not rpint at all.

Maybe you can share your expertise on htis issue?

I Also tried the Postscript driver and the first job goes ok. But on the next job I get "Unable to write print data: Broken pipe"

after second page.

lpstat shows device and scheduler is also started

Hi @hemant5400z,

Maybe you can share your expertise on htis issue?

I'm going to be honest with you, I don't have much 😄

It looks like a CUPS-related issue so I'd suggest you to reach out to the team that maintains the Debian package, the maintainers of the upstream project or give a shot to a more generic support channel (Linux IRC chatroom, Debian forum, ...) to troubleshoot. It could also be related to the driver, etc.

Good luck with your troubleshooting & don't hesitate to share any findings!

Hi,

I thought it was indeed but i installed the same version manually (no docker) and i don’t have any issues and can print without any problems.

The problem occurs when using synology and docker.

I tried lpd and socket both give the same problem.

So looks like something is missing when passing print jobs through synology and docker. Hemant

Are you sure that the version & the runtime environment are exactly the same? (same version of Debian, same configuration, same packages installed, etc.).

[olbat]

Could the broken pipe issue be related to some firewall / Synology configuration issue?

[hemant5400z]

Firewall not sure why wouldnit print 2 pages.

I allowed 5353 and 631 to tje firewall for mu subnet and to be sure also for the bridged 172.zxx.

But it gave the same error.

You are right runtime is not 100 % as mij virtual machine is based on ubuntu.

Only cups version is the same.

Could you try to install the same version of the drivers than the ones that managed to get working?

[hemant5400z]

For cups you mean?

It is version 2.3.3 with gutenprint 5.3 which i recall is the same as jn the docker.

Not really, I'm speaking about the drivers for your printer (that are used by CUPS).

[hemant5400z]

Hi,

I used the exact same ones as in the docker; Gutenprint 5.3.3 HP3800DN

Hi Luc,

I have been troubleshooting for a while and seems alls is working now on a Synology running DSM 6.2.3. After I found that for the HP3800DN the Foomatic drivers working i ran into another issue; while the printer was issible on IOS and the test page from cups admin was sucessfull i always got the message " printer offline".

So I started the docker slightly different

expsing both 631 and 5353 and not using --host (trial on error). For some reason now it works both PCL and Postcript in color and duplex.

Now i can use the synology as a print server!

cheers, Hemant
