When I choose "2 per page" for printing a pdf file (Canon MX922) it moves the file to half the page but prints only one copy on half the page.  How do I get it to print 2 pages on one sheet?
On letter sized photo paper I want to print the same photo 4 times each 3-1/2 X 5.  When I use the layout for the 4 photos it then doesn't give me the option to choose letter size page. Printer is Pixma MX 922
When printing cards it is printing off center on card stock.  When I print on plain paper, it prints centered.  How do I get it to print centered on the card? Printer is pixma mx922
What app do I need to download to print from my Android phone to MX922 printer.  I have tried a couple and have not been able to print an e-mail.
