A printer using ink jet printing technology to print one or more colors on a sheet for use in a box is described. The printer has a feeder, a transport mechanism for moving the sheet the print head, and a stacker to receive the printed sheet. Differential air pressure is applied by a suction box disposed in proximity to a conveyer belt for transporting the sheet. The suction box may sized so that the sheet may be oriented with a long dimension in the direction of feeding. Where multiple print heads are used, the print heads overlap in the direction transverse to the motion of the sheet so that an image larger than a print head may be produced. Two printing mechanisms disposed opposite each other may be used to print two sides of a sheet.
