where n may be in the range from 0 through 4. Values in the range
5-255 are invalid.
n = 0 or 48 (hex 00 or hex 30) selects DP print quality
n = 1 or 49 (hex 01 or hex 31) selects Near Letter Quality (NLQ)
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
Discussion This command overrides control panel print quality selections.
Selecting an OCR print quality overrides any character attributes
set, such as condensed, double-wide, etc. Setting character
attributes when OCR is set may cause unexpected results.
† Draft, OCR A, and OCR B print qualities (
n
= 2, 3, or 4) are not
defined in Epson-FX printers.

Note Some print attributes (such as condensed, double-wide, etc.) may not
return to their previous setting when changing from OCR-A or OCR-B back
to another Print Quality. For guaranteed results, all print attributes should
be set after the Print Quality is selected.
