Enter a five-digit zip code and the inches to print from the left and top of
|
29 |
the page or envelope. Don't forget that laser printers can't print all the
|
30 |
way to the edge and so the value you enter must be adjusted accordingly. For
|
31 |
example, if you enter 5.0 for the "From Left" value and the printer has a
|
32 |
1/4" non-printable border, the bar code will be located 5.25" from the
|
33 |
actual edge of the paper.
|
34 |
|
35 |
NOTE: Be sure to change the constant PrinterPixPerInch to match the
|
36 |
resolution of your printer.
