WPS Office has not found any installed printers

Installed WPS Office in two computers (Ubuntu 18.04 x64), one through snap and one though apt. I have a printer connected to another server, which is published using cups, and works fine in other applications (like libreoffice, pdf viewer, etc).

In both the clients, it shows the error: "WPS Office has not found any installed printers" when clicking the print button or from the menu.

I couldn't find any solution so far. Any way to debug this issue or to solve it?

The answer was provided in a rejected edit by an anonymous user. I'm posting the proposed solution as it results to be useful:

sudo snap connect wps-office:cups-control :cups-control

For WPS Office 2019:

sudo snap connect wps-2019-snap:cups-control :cups-control

Note: You can check the name of snap package in $HOME/snap folder.

After that, open the application and the printers will be shown as expected.
