I am trying to print an 11 x 18 in Adobe InDesign CS4 however, it will print automatically to an 8.5 x 11. I have tried to set the printing preferences but It defaults back to 8.5 x 11. This issue only happens in InDesign and not other Adobe products. My operating system is Windows 7 64-bit and the printer is a Toshiba E-Studio 3530C. Could this be a pnnter driver issue with Adobe InDesign CS4.
Try this: go into the print driver (the "Setup..." button at the bottom of InDesign's print dialog box) and set your custom paper size there. Then, back in the InDesign dialog, set the Paper Size to "Defined By Driver."
