I finally unboxed an old inkjet printer I've had in storage for 10 years and would like to use it with my desktop PC. Unfortunately, it's a huge printer -- a Canon Pixma Pro 9000 MarkII (got it for $50) -- which is capable of printing 13x19. There's just no place for it in my office and it won't get used often, so I connected it to an old laptop in my basement. The printer has no network capability and is connected to my laptop via USB. The laptop does run Windows 10. On the sharing tab in properties, I checked 'share this printer.' And, just for good measure, I turned on network discovery on the laptop. What else do I need to do?
