I have tried to print from my new Pi 3, using Libre Office Writer and an HP 5100 series inkjet which works OK with other Linux machines. It won't print: I get an error message saying "could not start printer" and suggesting that I check the printer settings. When I do that, I find that they treat my printer as a generic printer, SGENPRT, and I cannot change some of the settings, while those that I can change are already what I normally use.
