Learn to register the correct paper size when you print using AirPrint on an iOS device.


When you print with AirPrint® from an iOS® device, the default settings are.

  • Photos  - 4x6 Photo Paper

  • Documents - Letter size/plain paper

 If your printer has the option to register paper information (found in either Feed settings or Cassette settings depending on the model) and the printer setting to detect paper mismatch is enabled, you can specify the size and type of paper loaded in your printer.  AirPrint will use this information when you print a document or a photo.

  • Some models may default to printing on a 120 mm x 120 mm disc.

When you print photos

These examples show a PIXMA MG6820 used with the registered paper information set to Letter size/ Plain Paper, printing from the Photos app.

  • If the registered paper information is set to 5" x 7" Photo Paper Plus Glossy II:

  • If the registered paper information is set to 4" x 6" Photo Paper Plus Glossy II:

  • If the printer is not set to register paper information, it will use the defaults for AirPrint (4" x 6" photo paper in the Photos app):

  • If you have a registered paper size and type set on your printer, note that when printing from Photos, you cannot specify the size and type of paper you wish to print on from within the Photos app.

When you print documents

Registered paper sizes will also appear when you print documents from an app.

For example, when you use Safari after you specify Legal sized plain paper:

 Although the screenshot indicates that double-sided printing is enabled, you cannot print double-sided on Legal sized paper.

  • If you either have Letter sized plain paper registered in the printer, or if you have paper registration disabled, the size of the paper would not be shown:

  • If you print from a machine that has more than one feed source, you are able to specify which size of paper you want to print on if you have different sizes registered for each paper source.  For example, use the PIXMA TR8520 with 4" x 6" paper registered in the rear tray:

If both the rear tray and the cassette for the PIXMA TR8520 were set to use Letter sized plain paper, you would not be able to see the paper sizes to choose from.

If your printer supports plain paper from two different sources, the printer will feed paper from the default source.

  • For example, the PIXMA TR8520 would feed plain paper from the cassette.  However, if there was no plain paper in the cassette, or if the cassette was not inserted, then the printer would feed plain paper from the rear tray.

If your printer prints on discs, you will have an option to print on a 120 mm x 120 mm disc.
