this use to work but now it seems that cups is not setting the default printer using lpoption or something is failing in the setup.

This is happening on a product and on my person ubuntu 18.04 home machine

Thanks,
Terry

also seems that /etc/cups/printer.conf is not being populated with Canon printer info.

added information, the gui is seeing a canon printer in one of the "adds", it does not see any network printer if you you a find network printer.

Using the "Add" at the top of the printer gui, I was able to add the Canon printer, and printer.conf has all the info.

The gui adds a MG3600 printer instead of the Canon_MG3600_series that the qt qpinfo sees.

Looks like none of the command line commands can be used to add default printer which breaks my embedded qt app.

Thanks,
