Select Double Strike

A756 Emulation
ASCII:
Hexadecimal:
Decimal:
Value of n:
Turns double strike mode on for the slip station. Overprints a second
pass of the print line on the slip station to improve penetration of
multi-part forms and increase print contrast. The second pass is printed
the same direction as the first to ensure accuracy of the overprint. The
printer is reset to the standard print mode after a line has been printed
or after a Clear Printer (0x10) command is received.
Exceptions:
The settings do not apply in Page Mode. However they can be set or
cleared in Page Mode.
Double-strike printing cannot be used with bit-images or downloaded
bit-images.
This command functions the same as the 7156 when the printer is in
A756 Emulation Mode. In Native Mode, the command takes a
parameter to enable and disable it.
Related Information:
Printer output is the same as in Emphasized Mode.
