Ah! Try using Illustrator and in the print box goto Setup then select tile full pages.
You want to select "imageable areas" not "full page" otherwise you will get white gaps around each page because you are telling it that your printer can print full bleed... with imeagable areas it accounts for your printers print area
thanks dspring but on yours it says over lap i cant find that on mine or find out out to make a border around the art work so it will be easer to tape together. i never used illustrator. i think i should start
