Remarks

CanonSCR prints a displayed image on a Canon BJC-800 and BJC-820 Color 
Bubble Jet printer in graphic mode. There is optional disabling of form 
feed, changing brightness, port, or file.

The program should be run when the image is displayed. It expects that the 
video card is currently in a graphic mode and that an image is being 
displayed before the call is made. All coordinates must be passed. You must 
use TextMode (part of Sunshow, standard edition) to reset the video card 
back to text mode.

The BJC-800/820 supports cut sheet, plain and coated paper, envelopes, and 
transparencies up to 11.7" x 17.0". The Canon BJC-800 has a Centronics 
parallel interface, with an optional, separate SCSI board available, while 
the BJC-820 has both Centronics parallel and SCSI interfaces. Sunshow Pro 
currently does not support the SCSI interfaces. Epson LQ-2550, LQ-Color, 
LQ-1050 (monochrome only), and LQ-850 (monochrome only) emulations are 
available. Plain paper is suitable for text only, coated paper is required 
for maximum presentation quality, especially for images. Canon accepts A4, 
A3, letter, legal, and ledger size paper.


Example

The following example will print a 5.0" x 3.6" image at 360 DPI at the 
upper left corner of the page from the screen.
