I am attempting to print a document from illustrator with document (artboard) size of 4.25in x8in on paper that is 8.5 by 11. I've set up the printer settings in illustrator to print on letter (8.5 x 11) however the paper width in my print summary is listed at 9 by 11 for some reason and all of my test prints so far have turned out one inch larger (5.25in x 9in). Does anyone know how to correct this or where I might ahve gone wrong?
Make sure the page size is set correctly in the print settings dialog box. If you're wanting the artwork to print at actual size check to make sure no settings are checked to scale the artwork to fit the page.
Normally for printing on standard sheets of paper I'll make my art board size the same size as the sheet of paper. If there is a border or edge to an artwork design I'll make a rectangle that size to represent it rather than using the artboard for that purpose.
