Configuring the PCL-II Emulation with Control Codes
UPC E
A fixed-length data string of 11 ASCII characters may be printed using the
UPC E bar code. The string length must be 11 and may use any of the
standard characters 0 through 9 (however, the data pattern must meet the
format of UPC E bar codes; UPC E is a shortened version of very specific
patterns printable with UPC A). If a non-valid character or string length is
used, a blank non-readable bar code will be printed; non-valid characters are
not substituted or deleted. For UPC E, a zero (0) is required in the first
position of the bar code data (the number system character). The width of the
printed bar code is not variable and is 0.81 inches.
EAN 8
A fixed-length data string of 7 ASCII characters may be printed using the
EAN 8 bar code. The string length must be 7 and may use any of the standard
characters 0 through 9. If a non-valid character or string length is used, a
blank non-readable bar code will be printed; non-valid characters are not
substituted or deleted. The width of the printed bar code is not variable and is
1.25 inches.
EAN 13
A fixed-length data string of 12 ASCII characters may be printed using the
EAN 13 bar code. The string length must be 12 and may use any of the
standard characters 0 through 9. If a non-valid character or string length is
used, a blank non-readable bar code will be printed; non-valid characters are
not substituted or deleted. The width of the printed bar code is not variable
and is 1.56 inches.
Royal Mail
A variable length data string may be printed using the "Royal Mail 4 State
Customer Code". The string may use any character from 0 through 9 and
alpha characters A through Z. A complete bar code consists of a set of distinct
bars and spaces for each character followed by a checksum character and
enclosed by a unique start bar, stop bar and quiet zone. A second version of
the Royal Mail barcode prints with no stop bar, start bar or checksum
character.
The KIX format for Royal Mail does not include the start/stop code or the
check digit, but will allow lowercase alpha characters a through z.
UCC/EAN 128
The UCC/EAN 128 bar code contains special characters which use unique
codes to identify the leading and trailing end of the bar code. EAN/UCC 128
supports a full ASCII character set and provides standard alphanumeric
keyboard characters and control and special characters.
The EAN/UCC 128 data structure requires an Application Identifier (AI) at the
beginning of barcode data. Each AI determines the format and length of the
data which follows. Refer to Table 5 for more detail.
