While most forms today are done on 8 1/2 x 11 paper - actually most are filled in using a PDF editor and then dumped to normal size paper I recently found myself needing to scan forms from my new physician and enter them into my PDF editor. The Staples legal-size paper worked flawlessly in my Lexmark 4000C Pro printer and even in my Brother MFJC470DW (I bought that at my local Staples primarily for doing the occasional photographs and graphic files for very fussy clients. I never experienced the first jam in either printer and quality was as expected for a plain paper.
