I just imported 12 x 12 print module templates for printing photo collages files into PSE, but i am having an issue with the page set up. My 12 x 12 templates are appearing as 8.5 x 11. I cannot find the "Manage Customs Sizes" option under the page set up. In fact - when I select page set up I get the print set up - i confirmed I have the print to file selected and custom package selected too. When I select the custom file dimensions button and set the size to 12 x 12, it resizes the template but the cells on the right side are cut off. if i reselect the template the page returns to 8.5 x 11. I can confirm the templates are square as they appear that way in the preview box in the top left. I am on Windows 8.1 using the latest LR version (5.6). Any suggestions?
I solved my own problem by installing a wide format printer (Epson Stylus 1400) driver. Even though I don't have that printer.
