ESC O
Disables the skipover perforation (IBM/EPSON).
ASCII Code ESC O
Hexadecimal Value X'1B' X'4F'
Decimal Value 27 79
This sequence sets the number of lines of the skipover perforation to the value 0. Any skip perforation set
by ESC N is cancelled.
ESC Q
Sets the right margin. (EPSON)
ASCII Code ESC Q n
Hexadecimal Value X'1B' X'51' n
Decimal Value 27 81 n
Range 1 ≤ n ≤ 225
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
Double Width 5 1 ≤ n ≤ 67
6 cpi 1 ≤ n ≤ 81
7.5 cpi 1 ≤ n ≤ 101
8.5 cpi 1 ≤ n ≤ 111
10 cpi 1 ≤ n ≤ 135
Normal 10 cpi 1 ≤ n ≤ 135
12 cpi 1 ≤ n ≤ 162
15 cpi 1 ≤ n ≤ 203
17 cpi 1 ≤ n ≤ 232
20 cpi 1 ≤ n ≤ 255
24 cpi 1 ≤ 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.
