Meraki MX85 and MX105 block printing

[Ángel]

Good morning,

We have several MX85 and MX105 distributed around the hotels. Since a few weeks ago, they reported to us that they could not print. The error that showed us was "PCL XL error Kernel" and what caused was that it blocked the printer, forcing a reboot to work. This error happens with many printers, not all, of different models and brands (CANON, Brother and Xerox).
We have found the "solution". If we divert the traffic from the Meraki, that is to say that it goes directly through the switch and not through the Meraki, the printers work correctly. I have checked the logs and the dashboard blocking but it does not show anything.
I have updated the Meraki going through 18.107.2, 18.107.6 and 18.205, but nothing has changed.
What could be happening?

Thanks, best regards.

I had this same problem in versions 18.x, unfortunately the only way I was able to solve the problem was by downgrading the version.

Thanks for the answer.
What version do you have applied?

Unfortunately I'm still stuck on MX 16.16.9 because of this issue and a few others.
