PQ-8P, PQ-8S

To print any of these bar codes, use the following format:

¬B<type>,<height>,<width>,

<hr>,<chkd>,<ast>,<data>¬B

The bar-code command string must contain all of these parameters, even if the parameter is irrelevant for the type of bar code being printed. For example, POSTNET comes in only one size, so, any height or width specifications are ignored. But the parameters for height and width must be included anyway.

¬B: Identifies the strings as a bar code command string. ¬B must be placed at the beginning and at the end of the string.

<type>: Specifies the bar code type according to Table 6-1.

<height>: Specifies the height of the bar code. Height is expressed in multiples of 2.5 mm (approximately 1/10 inch). The height of the bar code can range from 1 (2.5 mm) to 9 (22.5 mm) inclusive.

Height values are ignored if a POSTNET bar code is being printed, since POSTNET uses one standard height. However, a valid value (1-9) must be entered for the height parameter to ensure the bar-code command string is complete.

<width>: Specifies the width of a bar-code module. A module is defined as a specific combination of bars and spaces used to represent a human-readable character.

By changing the width parameter, you can determine the width of the module and the thickness of the bars and spaces.

Width parameters can range from

1 to 9.

To determine the total length of the bar code, simply multiply the module length (found in the table on the following page) by the number of bar-code characters.

NOTE

Be aware that the table gives rounded values only.

Example: Using Code 3 of 9, you want to bar code the word “PRINTERS.” Assume the PQ-8 also generates a check digit and the start/stop characters. Setting the width parameter to 2 will yield a total bar code length of approximately 4 cm or about 1-1/2 inches.

Number of characters: 11 (8 letters (PRINTERS) + 2 start/stop characters + 1 check digit)
