OnlyOffice Desktop

NethServer Version: 7.7
Module: OnlyOffice

HI, everyone,
I installed Onlyoffice Desktop to work on my documents on nethserver.
On windows clients I have not encountered any problems with printers.
I installed the same client on an Ubuntu PC and when I go to print I don’t see any printer but only the Print to File (PDF).
I have also written in the OnlyOffice community but have not received any reply.
I only ask if you have also encountered this problem.
Thank you all
