BARCODE The Bar Code command; enter BARCODE.
UPC–A Designates bar code type UPC–A; enter UPC–A.
+n Optional parameter to provide a 2– or 5–digit add–on
code at the end of the bar code data field. Enter a plus
sign (+) and a value of 2 or 5. The first bar of the
add–on code is separated by nine modules from the last
bar of the UPC symbol and a left guard pattern.
VSCAN Optional parameter to orient the bar code structure
vertically. To select a vertical bar code, enter VSCAN.
If VSCAN is not entered, the bar code is oriented
horizontally.
SCB This option shortens the length of the center guard
bars, which are normally full length.
MAG Optional parameter to magnify (horizontally expand)
the bar code symbol. The magnification default value
is X1. Enter a magnification value to increase the
magnification. Increasing the magnification adjusts
printed character density.
You can also use XR or XRD as defined on page 5–4.
(You must specify 8 digits for MAG for variable ratio.)
