摘要：A laser printer is provided with the ability to receive and sequentially printportions of an image substantially larger than the cut paper sheet size or sizes theprinter is ordinarily configured to handle. The outsized image to be printed is input to theprinter controller and stored in its memory. An oversized cut paper sheet is then foldedin half and placed in the printer's manual feed area with the folded side edge of thesheet against an alignment guide and the doubled front edge of the sheet against theedge sensor portion of the printer. The printer's \"PRINT\" button is then pressed. Viaoperation of the printer controller microprocessor, a first signal representative of halfthe stored image is responsively output to the printer's laser generator, therebyimprinting 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 feedarea against the alignment guide, and presses the print button again. This time theprinter controller outputs a second signal representative of the balance of the storedimage to the laser generator, thereby imprinting the balance of the image on theunderside 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 11×17\" sheetan image scaled to essentially fill the sheet.
