Hello,
I am trying to use Virtual Here Linux client with M2020 printer. I am currently using the client on a windows machine and it is works fine. Now, I am trying to use the linux client and it is failing. I have the following log messeges:

Notice here that the driver is constantly removed. At these moments I am trying to send printing jobs but nothing happens. It seems that the driver is crashing.
On the server side, there is a Raspberry PI running an instance of the virtualhere server as service.
Can you help me solving this issue?
.
Thanks for the log. Those messages show that the driver is resetting the printer.
Its not going to be debugable unfortunately as i don't have that printer to test with so for the time being its not going to work via virtualhere.
.
Thanks for your feedback.
ok. I am available to help you in this M2020 support. I think it is good for your software product.
Feel free to send me instructions or request more logs. I am an electronics engineer, so, I think I can help.
.
Is it possible to plug the printer directly into the linux computer to see if it works that way, without virtualhere?
