I have several Ubuntu 20.04 LTS desktops configured to print to a CUPS print server with 4 printers. 3 of the printers work OK, the other one I can print a test page locally,
I would expect sending a test page from one of the desktops would result in the test page printing.

4) but sending a test page from one of the desktops results in the client CUPS showing:
Paused - "No destination host name supplied by cups-browsed for printer "Grassjewel", is cups-browsed running?"
When I check on the desktop system:
systemctl status cups-browsed
 cups-browsed.service - Make remote CUPS printers available locally

Additional information: The 3 working printers are different manufacturer laser printers, on the network. The problem printer is an Epson dot-matrix printer connected to the CUPS server via a USB/Parallel converter.
Log files and core dump attached.
