Font Parameters

This section describes the parameters for creating the fonts used in bar codes.

T Parameter

The T parameter controls which type of bar code is used. The command for specifying the T parameter is as follows, where T is a typeface number.

p Parameter

The p parameter, <Esc>(s#p, controls whether a human readable text caption is printed with bar codes, and the method used to print it.

1D Bar Codes

The numbers below represent the values that are used to define the commands in the escape sequence.

0:	Uses the default value.
1:	Does not print human readable text.
2:	Prints embedded human readable text.
3:	Prints human readable text that is half-embedded.
4:	Prints human readable text under the code.
5:	Prints human readable text above the code.

Example: If 24p is entered as the 1D bar code using the p parameter, the text for the French postal bar code is placed under the code.

NOTE
Add 10 to print the UPC/EAN/JAN checksum in the middle left, rather than the bottom left of the bar code. Add 10 to print the start and end characters for the 39 bar code text. Add 20 to format text for the French or German postal bar codes. Add 100 to print the checksum character with the text.

Example: If 402h is entered as the 1D bar code using the h parameter, the text will be in Univers Bold Italic, and the text size will automatically be selected.

v Parameter

The v parameter, Esc(s#v, controls the bar height and the number of rows or columns that are used for the bar code.

1D Bar Codes

Controls the bar height in increments of 1/60" (0.42 mm).

If the value entered is lower than the minimum bar height, it is automatically adjusted to the minimum value.

Example: Bar code of 1" (25.4 mm) in size: 60v

#4:	If "1" is specified, the PDF-417 symbol is truncated on its right side. If "0" is specified, the PDF-417 symbol is not truncated (default).

Example: 8 columns, 10 lines mandatory size, non truncated: 8,10,0b

Code 128 Control Codes

Code 128 has five non-data special control codes called Function Codes, and three control codes which enable the Bar Code Printing function to switch from one 128 set (A, B, or C) to another one. The switching of the control codes is used to force one 128 set. For example, the string "123456" can be printed with all sets A, B, and C. Inserting a character with an ASCII code value of 134 at the beginning of the string, forces the system to use set B of code 128.

NOTE
Both Code 128 Autoswitch and EAN 128 analyze the data and optimize the bar code length by switching automatically between sets A, B, and C. EAN 128 and UCC-128 already include the FNC 1 code as the first character. Therefore, you should not send the FNC 1 code along with EAN 128 and UCC-128 data.

Special control codes are included in bar codes by inserting the following numeric characters into the bar code:

128 = SHIFT	Used to switch from character set A to B, or from B to A temporarily. The change applies to the character following the Shift character. All subsequent characters are then given in the original character set.
129 = FNC 1	Reserved for future use or special applications, such as UCC-128 shipping container codes.
130 = FNC 2	A special instruction for the bar code reader to temporarily store data, append it to the symbol containing the FNC 2 character, and then transmit it together with the next symbol/character.
131 = FNC 3	Reserved for bar code reader initialization and other special bar code reader functions.
132 = FNC 4	Reserved for future use or special applications.
133 = CODE A	Used for numbers, ASCII characters, and upper case letters.
134 = CODE B	Used for numbers, ASCII characters, upper and lower case letters, and all numeric codes.
135 = CODE C	A double-density code, which is required to have an even number of characters.

NOTE
Values cannot have decimals. For example, "2.5" is an invalid value. Bar code parameters must be combined in a unique PCL escape sequence ending with the T parameter. Example: <Esc>(s4p305h24v7,21s7,21b24670T When using default parameters, only commas are required if other parameters still need to be defined. Example: <Esc>(s6p1,,,5s24850T
