Compaq 5525B/31/32 manual Bar Code Width Information, Bar Code Number of Characters Sent

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:

	Table 11. Bar Code Character
Bar Code		Number of Characters Sent
Code 3 of 9		Variable
Industrial 2 of 5		Variable
Interleaved 2 of 5		Variable
UPCA		11
UPCE		11
EAN8		7
EAN13		12
UCC/EAN-128		19
Postnet		5 (6), 9(10), or 11(12)
Royal Mail		Variable

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.
