EPSON WF-3620 won't print

[Gryphon 2580]

I hope I have posted this in the correct subject area. Educate me if I haven't.

About 10 days ago I got a new 5G Wifi router from T-Mobile. It was an upgrade to their Gen3 model because there are problems with the Gen2 overheating. I have an older HP all-in-one desktop running LM21, a refurbished Lenovo ThinkPad laptop running LM22, and an older Dell desktop running Windows 8. I updated the new password into the printer and the Dell/Windows machine will print fine, but neither of the Linux machines will print. I get one error window that pops up saying that 'cups-pki-expired'.
I tried the drivers manager - no success. I've searched the subject of 'Epson Printers' - 'Epson won't print' - and looked at the CUPS/Printer specific problems post, but didn't find or recognize any solutions.

So, does anyone have an idea or know of a fix?
Thank you for your time and knowledge!

my Epsom is not on a network, it connects direct to the laptop via the wireless in the laptop,
if you need drivers see

EPSON Download Center

download.ebz.epson.net

Yes, mine is connected to the Wifi network as well.
Thanks for the link, but downloading the indicated driver made no difference. I tried printing this post and it still won't print.

someone allegedly solved the "cups-pki-expired" error in linux mint with a WF-3620 2 years ago : https://forums.linuxmint.com/viewtopic.php?t=389433

if that doesnt work then:
- WF-3620 drivers, linux: http://download.ebz.epson.net/dsc/search/01/search/searchModule
- Epson documentation, linux (the inkjet stuff is pretty old though): http://download.ebz.epson.net/faq/linux/
- Epson user manuals, linux: http://download.ebz.epson.net/man/linux/

some arch specific documentation for Epson printers, but it might be worth trying: https://github.com/meyertime/linux-all-the-things/blob/master/docs/arch-epson.md

this is from ~7 months ago: https://superuser.com/questions/1845765/add-epson-network-printer-to-cups

hope that helps!

Thank you for the reply, sorry for the late response - been tied up a bit.

Yes, that was me a couple of years ago - and now with the same issue.
The problem is that, just as back then, I don't know what the results mean. And with a new router and laptop, I get different returns. I tried running through the commands as posted, but I still have no success.

Is there someone who understands the commands and results and can would be willing to guide me through the steps?

did you download the deb package to install the drivers ? from here - http://support.epson.net/linux/Printer/LSB_distribution_pages/en/escpr.php

you also need to make sure libcupsimage2 is installed it is a prerequisite

 

[Gryphon 2580]

I had downloaded the drivers.

I ran the 'get install' command and it appears that I do have the latest version:

outis@outis-ThinkPad-P17-Gen-1:~$ sudo apt-get install libcupsimage2
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'libcupsimage2t64' instead of 'libcupsimage2'
libcupsimage2t64 is already the newest version (2.4.7-1.2ubuntu7.3).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I rebooted and still no success. I still get the cups expired message

Is there a reset button on the printer?

Quite possibly very small and out of sight

 

[GatorsFan]

The only other thing I can think of is look in /etc/cups/ssl and see if there is a epson.local.crt file in there (you will most likely need to be root to do this) - if there is delete it and reboot

 

[Gryphon 2580]

There is a reset button, but it says that this operation is invalid.

I have searched for the directory and file, but came up empty.

Might be time for a new printer, but I don't understand why the window machine still connects and works after the router change and Linux doesn't when this cups issue has been around for awhile?

 

[Condobloke]

There is a reset button, but it says that this operation is invalid.

'Reboot' the printer following that ?....unplug it for a minute and then plug back in ?

 

[Gryphon 2580]

Yeah, I've tried that a couple of times - no success.
