Abstract: A method for extending a print area provides a printer with the capability of printing a larger image by extending the print area during the printing of an image. The method extends the print area by means of a window driver which transmits an image to be printed to a printer according to a print command input. The method includes a first print step of the window driver for transmitting a first portion of the image to be printed on a piece of paper, the first portion being bounded by a lower end margin of the piece of paper, and a second print step of the window driver for transmitting a second portion of the image to be printed on a portion of the piece of paper below the lower end margin of the paper. Accordingly, since the printable area becomes larger by reducing the lower end margin of the printer to the level of the upper end margin, documents created by a user (such as CAD drawings, graphics and charts) are printed without being cut.

Abstract: A device and method for automatically opening the cover of an ink-jet printer using a solenoid driving device, which responds to an electrical signal sent from a controller unit because the unit detected either a paper jam or that the ink cartridge is depleted. The new mechanism for automatically opening a printer cover allows the user to remove jammed paper or to replace the spent ink cartridge with greater speed and efficiency. This device has the advantages of being economical for use in ink-jet printers and employs a simple design which minimizes the need for repair and simplifies the manufacturing process.
