FCC: Encoding Table: Specified by typeface number (FCC 45 not available) Specified by #p parameter (default is 1, which is C table) Function parameters for Singapore Post 4-State bar code (HP compatibility mode, using typeface 24780) In relation to the fields of the Lexmark bar code descriptor for Singapore 4-State Postal bar codes, the following correspondences exist when using this technique: Bar Width (in 1/100 mm units): Bar Pitch (in bars per inch): Tracker Height (in 1/100 mm units): Ascender, Descender Offset (in 1/100 mm units): Fixed at 47 Fixed at 22 Fixed at 123 Fixed at 195 Specifying bar pitch for USPS POSTNET For typefaces 24770, 24771, and 24772, the S1 parameter specifies the bar pitch in bars per inch. A bar pitch value of 20 will be used for any bar pitch that is less than 20. A bar pitch value of 24 will be used for any bar pitch that is greater than 24. The default value is 22. USPS Zebra code The USPS Zebra code is a series of diagonal or vertical lines placed to the right of a USPS tray label bar code to visually identify trays containing bar coded mail. The lines should each be 0.250 inch to 0.375 inch (6.35 mm to 9.52 mm) high, 0.125 inch to 0.250 inch (3.18 mm to 6.35 mm) wide, and should be separated by blank spaces equal in size to the line widths. The only valid characters in this symbology are "/" (ASCII 47) and "|" (ASCII 124). Spaces between bars are automatically inserted. The base of each successive bar is printed beginning one space width from the right end of the base of the previous bar. The widths of the bars and spaces for this symbology are fixed. In the case of a diagonal bar, the width of the bar refers to the width of its base. An invalid character in the data produces a blank space in the symbol equal to two space widths, and does not produce an error message. If an invalid character follows a valid character in the data, then the blank space produced by the invalid character begins one space width from the right end of the base of the bar produced by the valid character. • If the last bar of a symbol is a diagonal bar, then the cursor is positioned one space width from the right end of the base of the last bar when printing is complete. • If the last bar of a symbol is a vertical bar, then the cursor is positioned at the right end of the base of the last bar when printing is complete. • If a blank space produced by an invalid character is the last thing printed in a symbol, then the cursor is positioned at the right end of the blank space when printing is complete.

Function parameters for Singapore Post 4-State bar code (HP compatibility mode,
using typeface 24780)
In relation to the fields of the Lexmark bar code descriptor for Singapore 4-State Postal bar codes,
the following correspondences exist when using this technique:
Specifying bar pitch for USPS POSTNET
For typefaces 24770, 24771, and 24772, the S1 parameter specifies the bar pitch in bars per inch. A
bar pitch value of 20 will be used for any bar pitch that is less than 20. A bar pitch value of 24 will be
used for any bar pitch that is greater than 24. The default value is 22.
USPS Zebra code
The USPS Zebra code is a series of diagonal or vertical lines placed to the right of a USPS tray label
bar code to visually identify trays containing bar coded mail. The lines should each be 0.250 inch to
0.375 inch (6.35 mm to 9.52 mm) high, 0.125 inch to 0.250 inch (3.18 mm to 6.35 mm) wide, and
should be separated by blank spaces equal in size to the line widths.
The only valid characters in this symbology are “/” (ASCII 47) and “|” (ASCII 124). Spaces between
bars are automatically inserted. The base of each successive bar is printed beginning one space
width from the right end of the base of the previous bar. The widths of the bars and spaces for this
symbology are fixed. In the case of a diagonal bar, the width of the bar refers to the width of its base.
An invalid character in the data produces a blank space in the symbol equal to two space widths, and
does not produce an error message. If an invalid character follows a valid character in the data, then
the blank space produced by the invalid character begins one space width from the right end of the
base of the bar produced by the valid character.
If the last bar of a symbol is a diagonal bar, then the cursor is positioned one space width
from the right end of the base of the last bar when printing is complete.
If the last bar of a symbol is a vertical bar, then the cursor is positioned at the right end of the
base of the last bar when printing is complete.
If a blank space produced by an invalid character is the last thing printed in a symbol, then
the cursor is positioned at the right end of the blank space when printing is complete.
