Is Canon Imagerunner 2525 can print A3 paper?

No, the Canon imageRUNNER 2525 cannot print on A3 paper. It is designed to handle a maximum paper size of 11" x 17" (Tabloid size), which is smaller than A3 dimensions (11.7" x 16.5"). If you need to print on A3, you would need a different model that specifically supports that paper size.
