Chapter 1 EPSON/IBM Commands 25 260071 ‐ 001A
Character Width Horizontal Spacing Range of columns
Normal 10 cpi 0 = n = 134
12 cpi 0 = n = 160
15 cpi 0 = n = 201
17 cpi 0 = n = 229
20 cpi 0 = n = 255
Any value outside the accepted range is ignored and the previous setting remains in effect. The left margin
must be smaller than the right margin. The physical position set for the left margin does not change if the
horizontal spacing is modified. This command overrides the menu setting.
ESC N
Sets the skipover perforation to n lines (IBM/EPSON).
ASCII Code
ESC N n
Hexadecimal Value X'1B' X'4E' n
Decimal Value 27 78 n
Range 1 = n = 127 (EPSON mode)
1 = n = 255 (IBM mode)
The skipover perforation is the sum of the top and bottom margin values at the selected vertical spacing.
The n parameter must be less than the current form length. The skipover is retained as the physical
position on the page. It is cancelled by ESC O or changing the form length.
The skipover value, when accepted, sets the top and bottom margins according to the operator panel
setting (see the Administrators Manual):
If the top margin set using the operator panel is greater than the skipover value, the following value of the
margins is set:
Top margin = skipover value
Bottom margin = 0
If the top margin set using the operator panel is less than or equal to the skipover value, then the following
value of the margins is set:
Top margin = operator panel value
Bottom margin = the difference between skipover value and top margin value
If the sum of the top and bottom margins values set using the operator panel is less than the skipover
value, the following values for the margins is set:
Top margin = operator panel value
Bottom margin = the difference between skipover value and top margin value
Changing the vertical spacing does not affect the skipover distance. This can be changed by another ESC
N command or can be reset by the ESC O command, which resets the skipover value to 0. The skipover
perforation is performed when the end of the page is reached with a LF, VT or FF code and not with the
ESC J or ESC C command. The skipover perforation is cancelled and must be reset.
