PIXMA TS7720 Printer won't print from desktop

[GME58]

Pixma TS7720 won't print from desktop.  Never had problem before.  The desktop says that the computer is on-line and the print dialog box appears.  Also, scanning function works.  I can print docs using laptop, so it doesn't appear to be a printer problem.

What happens, does the printer do anything or just sit there, no error on your screen? Any changes to your desktop?
