How to set up a custom user defined paper size for your inkjet printer with Photoshop CS5 CS6 CC on a Mac

For Red River Paper greeting cards, scrapbook 12x12 sheets, panorama printing, and other special projects, you need to define a custom paper size in the printer properties.

Canon Printer Alert - Canon printers can use sheets up to 26.6" long. This rule is hard wired into the driver by Canon and cannot be overcome.

TO BEGIN

Go to FILE > PRINT in Photoshop.

Choose your printer from the Printer drop down menu

Then click PRINT SETTINGS

PRINT DIALOG

Click the Paper Size drop down menu.

Under "Paper Size" choose "Manage Custom Sizes".

Custom Page Sizes

1. Click the + button to start a new size. Set the width and height.

2. Click on the new size and name it something appropriate.

3. Set the width and height of the custom size.

Width = the smaller dimension of your paper
Height = the longer dimension of your paper

4. Set Printer Margins. The smallest you can use is 0.15". We recommend 0.2" on all four sides. Setting the number lower will likely result in printing errors or partially printed images.

OSX may not handle custom paper sizes correctly. It is system and printer specific and may not happen to you. If it does, your margins will probably be off. Come back to this dialog box and adjust the Printer Margins. This may take some experimentation but is necessary.

Now name and save the new paper size for later use.

HANDLING 13x38 and 6x38

Newer OSX versions, 10.6 and up, have issues with handling custom sizes correctly. If your printer prints only a portion of the image, the image but in a smaller form, or will not print at all, you likely are seeing a custom paper size error.

Canon Printer Alert - Canon printers can use sheets up to 26.6" long. This rule is hard wired into the driver by Canon and cannot be overcome.

For 13x38 or 6x38

Set paper width to 12.95"
Set paper height to 37"

This avoids problems with the 3800/3880 max print length of 37.5". You'll still have room for a full 12x36 or 5.5x36 print.

Margins

Margins must be set to 0.2" or larger. Smaller numbers may result in OSX designating your size as a roll and the printer will not print.
