EPSON/IBM Mode

ESC Q
Sets the right margin (10 cpi). (EPSON)
ASCII Code ESC Q n
Hexadecimal Value 1B 51 n
Decimal Value 27 81 n
Range 1 < n < 255
This code sets the line length at the current horizontal spacing. It
must be sent at the beginning of the line. The n parameter specifies
the number of columns and for each type of horizontal spacing there
is a range of values, as shown in the following table:
Character Width Horizontal Spacing Range of columns
5 cpi 0 < n < 67
6 cpi 0 < n < 81
7.5 cpi 0 < n < 102
8.5 cpi 0 < n < 116
Double Width
10 cpi 0 < n < 136
10 cpi 0 < n < 136
12 cpi 0 < n < 163
15 cpi 0 < n < 204
17 cpi 0 < n < 233
Normal
20 cpi 0 < n < 255
Any value outside the accepted range is ignored and the previous
setting remains in effect. The right margin must be greater than the
left margin. The physical position set for the right margin does not
change if the horizontal spacing is modified.
ESC R
Sets all tabs to power-on settings. (IBM)
ASCII Code ESC R
Hexadecimal Value 1B 52
Decimal Value 27 82
This command sets horizontal tab stops every eight columns starting
from column 9 and cancels all vertical tab stops.
