This is an "all-in-one". After several frustrating hours got it working. Installed it and test print worked fine. Tried scanner from scan application and that worked (surprise!). Then tried printing from applications and it would not work. Traced to having named the printer "Fred's printer" or equivalent. Remove the single quote and all is fine!
I guess this problem would apply to any HP printer, and quite likely to others. Beware!
