cups-pki-expired

[clement]

Hello.
I use linux mint 20.1
I have a hp envy 4520 printer.
The printer is on a local network.
He is recognized by my PC.
But when i try to print i have "cups-pki-expired" error.
Whats wrong?

On a other pc with linux mint 18 it works without problem.

What do i have to do to fix the problem?

I have the same problem with Linux mint 20.1 and a HP officejet 3830 printer

[m (cups-pki-expired)]

I have the same error message with two Linux Mint 20.2 Cinnamon instances/laptops, and both two Kyocera TASKalfa 3252ci printers in this building.

It used to work fine for months.
