Print Quality
89
Print Quality
ASCII Code ESC x n
Hex Code 1B 78 n
Dec Code 27 120 n
Purpose This code selects a print quality.
where
n = 0 or 48 (hex 00 or hex 30) selects DP print quality
n = 1 or 49 (hex 01 or hex 31) selects NLQ print quality
n = 2 or 50 (hex 02 or hex 32) selects HS print quality
n = 3 or 51 (hex 03 or hex 33) selects OCR A print quality
n = 4 or 52 (hex 04 or hex 34) selects OCR B print quality
Comment When you select NLQ, the font is serif. Print qualities selected
with this command override control panel selections. Selecting
an OCR print quality overrides any character attributes already
set, such as condensed, double-wide, etc. These attributes will
not return when another print quality is set. Character attributes
set when OCR is selected will be ignored.
Proportional Spacing
ASCII Code ESC P n
Hex Code 1B 50 n
Dec Code 27 80 n
Purpose Enables/disables proportional spacing of characters.
where
n may range from 0 through 255 (hex 00 through hex FF).
n = 1, 3, 5...(any odd value) enables proportional spacing
n = 0, 2, 4...(any even value) disables proportional spacing
Comment This command is ignored when a non-proportional font is used.
