    If properly connected with a bi-directional interface, an external device may be used to check the printer status. When printing is executed in a Microsoft Windows or Macintosh environment, CAPT (Canon Advanced Printing Technology) serves to reduce processing speed and enhance the ease of operation to provide a user-friendly printing environment. To that end, CPU is designed for the following: - The print data from the application is turned into dot data and sent to the printer without conversion into the printer's page description language (PDL).
