If the top margin set via operator panel is greater than the skipover
value, then the following value of the margins will be set:
Top margin = skipover value
Bottom margin = 0
If the top margin set via operator panel is less or equal to the
skipover value, then the following value of the margins will be 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 via operator
panel is less than the skipover value, the following values for the
margins will be 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 a further ESC N command or can be reset by the ESC
O command, which resets the skipover value to 0. The skipover
perforation will be executed 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 therefore be set again.
ESC O
Disables the skipover perforation. (IBM, EPSON)
ASCII Code ESC 0
Hexadecimal Value 1B 4F
Decimal Value 27 79
This sequence sets the number of lines of the skipover perforation to
the value 0 and so any skip perforation set by ESC N is cancelled.
