The number of lines per inch and lines per page can be configured using the standard PCL escape code sequences. The value can be changed from within the HP emulation mode using the following PCL escape code sequence:
<esc>&l#e##F
Where:
l is a lower case L
# is the top margin
## is the page length (default is 60)
To enter <esc>, press the Ctrl-P keys followed by the Esc key.
Note: You must use an ASCII text editor like DOS EDIT. You cannot enter the <esc> character in some Windows-based editors like Notepad.
In addition, the following escape sequence can be used to set the number of lines per inch, allowing more lines per page by decreasing the empty space between each line.
<esc>&l#D
Where:
l is a lower case L
# is the number of lines per inch (default is 6)
There are several methods for downloading the information to the printer. From a standard PC that has BASIC available the following program will work. Be sure to replace the # and ## with the desired option values.
