A. Canon Advanced Printing Technology (CAPT)
1. Concerning Canon Advanced Printing Technology (CAPT)
Canon Advanced Printing Technology (hereafter referred to as CAPT) reduces the processing
time, and simplifies operations for printing in the Microsoft Windows environment.
CAPT performs the following procedures to enable easy and speedy printing.
• Instead of converting application print data into the printer's page description language
(PDL), this software translates print data into resource data corresponding to the writing sys-
tem commands (GDI data.)
• The resource data corresponding to the GDI data are developed into 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, which enables the user to confirm
the printing completion time, feeding status of the print paper, error conditions, and etc. on
the host computer screen.
Note: GDI : Graphics device interface
Graphic writing system to perform printing and screen display in the Windows environ-
ment, (and a graphic writing system interface for the application.)
CAPT is used by installing on Microsoft Windows NT4.0 or Microsoft Windows 95/98. The
installation is done using the Canon Advanced Printing Technology disk included with this print-
er.
CAPT specifies the paper size, document size, number of copies and print quality on the com-
puter screen. The operation methods of the dialog boxes vary in Microsoft Windows NT4.0 and
Microsoft Windows 95/98.
The installation procedures and operations are explained on the following pages. (Microsoft
Windows NT4.0: Page 1-12, Microsoft Windows 95/98: Page 1-49)
