UPC Descenders
This parameter allows you to print bar code descenders when human readable data is not
presented in the UPC/EAN bar codes.

Always (factory default). UPC/EAN bar codes are printed with descenders, even if there
is no human readable data.

Never. UPC/EAN bar codes are printed without descenders if the PDF command is
present.

Only With PDF. UPC/EAN bar codes are printed with descenders only when the PDF
command is presented.
C39 Compatible
This menu makes the old method of decoding C39 alternative character set compatible with the
new method. For example in the old method for barcode data, %K123%M, the barcode scans as
[123]. The new method scans the barcode as %K123%M.

Disable (factory default). Uses the current way of decoding.

Enable. Matches the old method of decoding.
I-2/5 Selection
This option is added to be compatible with a special IGP-X00 customization. Usually, if
Interleaved 2/5 bar codes have an odd number of digits, a leading zero is inserted in front of the
data. However, this special IGP-X00 customization gives you the option of adding a space
character at the end of the bar code instead.

Leading Zero (factory default). A leading zero is inserted in front of the data.

Trailing Space. A space is inserted at the end of the data instead of a leading zero.

X2 DPD. When selected, I-2/5 bar code with a magnification X2 will use the specially
configured ratios 3:3:6:5 rather than 3:6:9:12 for compatibility with other Printronix Auto
ID models.

Modulo 7 CD. The I-2/5 bar code uses a modulo 7 check digit instead of the default
modulo 10 check digit.
Select SO Char
Allows you to specify a decimal code from 0 through 255 to be used in place of SO (Shift Out) as
the control code which allows access for the alternate set of control function characters. See the
description of the Code 128 barcodes in the PGL Programmer's Reference Manual for details.
The range is 0 to 255, and the default is 14.
Vertical Adjust
This option is to adjust printer dpi to expand or shrink the vertical position of graphic elements
and the height of the vertical line. The factory default is 0 dots. The adjustment range is from -20
dots to 20 dots with respect to the current printer dpi.
