32 Line Matrix Printer PCL II Programmer's Reference Manual

Bar Codes

NOTE: When a header is enabled, sending one line of information causes

the printer to print two lines; one line containing the header along with

any text you may have sent in that line, and one line containing the

bar code label. When a header is enabled, no information can be

printed on the same line as the bar code label. However, if the header

is disabled, text can be placed next to the bar code label. For

example, if you want a label and also wish to enclose the bar code

with a box, you may not use automatic headers. Instead, you may set

the height of the bar code to the text height and manually print the

header.

Bar Code Width Information

The following paragraphs contain information concerning the size of the

printed bar codes. If you are designing a form that contains bar codes, this

information may prove useful in judging how much space the bar code will

occupy.

The following table lists the number of characters sent by the user for each

type of bar code:

NOTE: For Postnet Barcodes printed using the 5525B/31/32 style, if 5, 9, or

11 digits are sent, your printer will automatically calculate and print

the check digit. If 6, 10, or 12 digits are sent, the printer will verify the

check digit. Should the check digit be inaccurate, or an invalid bar

code length is sent, your printer will not attempt to print the invalid

data.
