The default "Generic" Printer throws "Could not start generic printer. Check your printer configuration". How do I make printing to PDF the default?

When I print from Libre Office and have the default "Generic" Printer, I get "Could not start generic printer. Check your printer configuration". What needs to be done so that I do not have to choose "Print to file" with the mouse each time I want to print a PDF? And even if I choose "Print to file" with the mouse, the file is not named with the name of the opened file, you need to write down the name. This is tedious work, you either have to write down the name or copy the name from the file name.
