LASER CARDS FOR HP 4000 TWINAX AND COAX PRINTERS
setting ignores print-quality settings and always prints COR (unless the host's page
rotation or the interface's APO setting determine the print orientation).
The Laser Card also has a second COR option. This COR option is a true 3812-
1 emulation. With certain page rotation settings on the host, the IBM 3812-1
printer allows the user to manipulate the final print orientation through the print
quality setting. Note though, that this "override" only applies if the interface's
print orientation is set to COR, host override allowed.The following tables show
what page rotation settings can be manipulated through print quality settings and
how the combination of page rotation and print quality affects the final print
orientation.
