USE
Barcode printing is generated by inserting special extended PCL5e commands into the data
stream. Once the required escape sequence has been received the printer will interpret the
following characters as barcode data until it receives a command that specifies the next
primary font for text printing.
After the barcode parameters have been selected, following text data is gathered for
processing the barcode image. The end of barcode data will be determined by the barcode
type, but in general it is indicated by
CR/LF/FF/
When the full sequence of text data to be printed as a barcode has been received, it is
analysed to ensure that it conforms to the correct number of characters and range of
character values for the specified barcode type. If not, an error code is printed.

SPECIAL
CHARACTERS
If you need to print special characters (0x00~0x1F) as barcode data, the Transparent Print
Data command must immediately follow the font selection sequence. This command is:
where the number # specifies the number of following data bytes.

COMPRESSION
Once the barcode data has been received and verified, it is compressed if necessary. Where
the barcode type prints compressed data the barcode printing feature allows the code to
be precompressed (6 characters input) or uncompressed (10 or 11 characters input). If
uncompressed data is sent but the barcode type requires it to be compressed, then the
compression is performed automatically.
