You cannot print edge to edge on any type of
paper stock (besides those small photo printers), there are always margins that the printer requires for the feed rollers, etc.
If you require a full bleed, then you will have to print on oversized stock and trim it down. You will have to contact a local
paper supplier or another local printing company to see if they will sell you some. Find out the largest stock your printer can take & maximize your yield, some even take 13x19 or similar sizes.
