Enable Upper Control Codes; Font Expansion - Printronix P7000 H-Series Programmer's Reference Manual

Enable Upper Control Codes

ASCII Code ESC 7
Hex Code 1B 37
Dec Code 27 55
Purpose Tells the printer to treat codes from 128 to 159 as control codes
instead of printable characters.
Comment This command affects the front panel setting of "Alt. Set 80-9F."
In the default mode, codes 128 to 159 are treated as printable
characters.

Font Expansion

ASCII Code ASSC
Hex Code ASSC
Dec Code ASSC
Purpose Expand the DBCS character up to the size of 72.
For this command to work, n1 must be the same value as n2
(i.e. n1 = n2). When n1 and n2 = 25 to 72, this set font
expansion mode is ON. The value of n1 and n2 will determine
the bitmap size. For example, if the size of n1 is 50, then the
size of the bitmap will be set to 50x50. For n1 and n2 = 24, the
font expansion mode will reset to OFF and the bitmap size
reverts to the default, 24x24.
Inter-line spacing and inter-character spacing calculations are
based on standard setting as if bitmap is 24x24. This command
will only increase the size of the bitmap and not affect inter-
character spacing or inter-line spacing. For example, if inter-
line spacing is 6 dot rows, when the bitmap is expanded from
24x24 to 72x72, the inter-line spacing still remains as 6 dot
rows. This is the same for inter-character spacing.
Other commands, such as double height, double width, 2x2
times, left/right margin etc., will not function when font
expansion mode is set on. For different typefaces, the
characters will expand based on approximate typeface
resolution. All commands affecting LPI and CPI will still take
effect and is set based on the bitmap being 24x24.
Where:
n1 = 24 ~ 72
n2 = 24 ~ 72
This control code does not function while in non-DBCS mode.
