I have a Canon Imageclass color laser printer, MF620C, windows 10. It has a "multipurpose tray" where you can manually feed the paper. I am using Adobe Indesign and my document size is 8 x 24 inches. However the printer won't print anything outside the standard size of 8.5 x 14 even if I go to custom settings, it won't let me register a different size in printing preferences at all. Any help appreciated. Thanks.
