Hello...I use a Canon Pixma Pro 100 and the Print Studio Pro software. I'm running Windows 10, and trying to print out of the latest Photoshop. When I send an image to the printer, it will simply not come out at the size I want; I'll set something to 8 x 10 in Photoshop, and it will come out much smaller. I can't find any way of adjusting it to be the size it's meant to be, and I have no idea why the software simply ignores the size I've selected. The various sliders for margins, etc, in Print Studio Pro do nothing helpful. Plus, I can't find preferences settings anywhere to get the controls out of metric and back to Imperial.
