VII. OPERATION
A. Canon Advanced Printing Technology (CAPT)
Canon Advanced Printing Technology (hereafter referred to as CAPT) reduces the processing time
and simplifies the operations for printing in the Microsoft Windows environment.
The easy operations and speedy printing are supported by the following features of CAPT:
• Instead of converting print data sent from application into the printer's page description lan-
guage (PDL), CAPT translates the print data into resource data compatible to the graphic
drawing system commands (GDI data.)
• The resource data compatible to the GDI data is developed to dot data, and then passed to
a host computer.
• The printing environment can be set in the dialog box on the host computer screen.
• The printer status is shown on the host computer screen, so users can view and confirm the
print time, print paper status, error conditions, etc..
