I am attempting to print from a laptop, and have tried printing from photoshop as well as Adobe Acrobat. I will select the option to print the file at 100% with it properly scaled beforehand. I will then select poster tiling and have also messed around with different ways to split the image. I have also changed the actual size of the image, as well as the dpi etc etc, but no matter what I change the printer itself seems to override any changes made to the image and scales the prints itself. I have been unable to find a way to change anything on the printer itself that would help.
Any help would be appreciated as I do not want to go through the hassle of returning this printer.
