I am currently using Photoshop to create panels for a home cockpit. In Photoshop, I have my Canvas set to 325mm by 115mm. I select Tablolid and make sure my scale is set to 100% and click print. But the print is about 5mm smaller than what I had selected in Photoshop. It is not my printer as I tried making the same sized shape in ArchiCAD and that printed out accuratly. What am I doing wrong?
