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): Fixed at 47 Bar Pitch (in bars per inch): Fixed at 22 Tracker Height (in 1/100 mm units): Fixed at 123 Ascender, Descender Offset (in 1/100 mm Fixed at 195 units): Specifying bar pitch for USPS POSTNET For typefaces 24770, 24771, and 24772, the S1 parameter specifies the bar pitch in bars per inch: 20-24. A bar pitch value of 20 will be used for any bar pitch given that is less than 20. A bar pitch value of 24 will be used for any bar pitch given 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. These lines are placed to the right of a USPS tray label bar code to aid in visually identifying trays containing bar coded mail. The lines should each be from 0.250 inch (6.35 mm) to 0.375 inch (9.52 mm) high, and from 0.125 inch (3.18 mm) to 0.250 inch (6.35 mm) wide. The lines 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). A "/" in the data produces a single thick diagonal bar in the symbol. A "|" in the data produces a single thick vertical bar in the symbol. 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. As noted above, 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, 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, the cursor will be positioned one space width from the right end of the base of the last bar 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:
20-24. A bar pitch value of 20 will be used for any bar pitch given that is less than 20. A bar pitch
value of 24 will be used for any bar pitch given 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. These lines are placed to the right of a
USPS tray label bar code to aid in visually identifying trays containing bar coded mail. The lines
should each be from 0.250 inch (6.35 mm) to 0.375 inch (9.52 mm) high, and from 0.125 inch (3.18
mm) to 0.250 inch (6.35 mm) wide. The lines 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). A “/” in the data
produces a single thick diagonal bar in the symbol. A “|” in the data produces a single thick vertical
bar in the symbol. 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. As noted
above, 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,
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, the cursor will be positioned one space width from
the right end of the base of the last bar when printing is complete.
