A laser printer is provided with the ability to receive and sequentially print portions of an image substantially larger than the cut paper sheet size or sizes the printer is ordinarily configured to handle. The outsized image to be printed is input to the printer controller and stored in its memory. An oversized cut paper sheet is then folded in half and placed in the printer's manual feed area with the folded side edge of the sheet against an alignment guide and the doubled front edge of the sheet against the edge sensor portion of the printer. The printer's "PRINT" button is then pressed. Via operation of the printer controller microprocessor, a first signal representative of half the stored image is responsively output to the printer's laser generator, thereby imprinting the image half on the underside of the folded sheet. After it exits the printer, the operator flips the folded sheet over, operatively re-inserts it into the manual feed area against the alignment guide, and presses the print button again. This time the printer controller outputs a second signal representative of the balance of the stored image to the laser generator, thereby imprinting the balance of the image on the underside of the sheet as it traverses the printer. In this manner, for example, a printer having only 8.5'' printing and paper feed widths may be used to print on an 11x17'' sheet an image scaled to essentially fill the sheet.
