Canonn ip4800

Hi all.
Good to find the site is back with the original team(?). Just got a Cannon ip4800 as my inkjet printer. One problem I’ve found I cannot work how to use a (Neato) jpeg file which is ready for printing. But there are no compatible files that I can see. Read the manual but see nothing about this matter. Anyone have any suggestions?
Cheers BC

What program are you using to open the jpeg with?
What print options does that program have?
