the barcode print facility is available in all three emulations.
2. programming
there are three escape sequences to print barcodes
1 the first sequence is to define the barcode header. the type of barcode as well as all parameters are selected by a header. the header does not affect any parameters outside the barcode application and remains valid until another header is transmitted or the printer is turned off. this can be done at any time but before barcode printing.
the header has the following format:
esc [ ; p ; p ; p ; p ; p ; p 8 z note: 8 = space 2 3 4 5 6 7
2 in step two, the esc-sequence "set mode barcode (smbc)" starts the 1barcode printing.
esc [ ? 0 h
3 finally, the esc-sequence "reset mode barcode (rmbc)" will stop printing. esc [ ? 0
between smbc and rmbc are only printable characters tolerated (no cr or lf).
code 93, msi 10/10, code 128 are fixed 2.0 to 1 best results for code 39, 2 of 5 industrial, 2 of 5 interleaved, and codabar with 2.5 to 1 p uni-directional or bi-directional printing - standard 0 uni-directional 7 values are: 0 or not programmed means no changes
1 uni-directional printing in lq
2 bi-directional printing in lq
3 uni-directional printing in nlq
4 bi-directional printing in nlq
a switch from uni-directional to bi-directional printing is only possible if the parameter uni-direct.cmd is set to yes via operator panel or esc-sequence.
start position of barcode printing
the start position for barcode printing is the current print position. for both horizontal and vertical printing, the print position after printing barcodesis the same line as the start position next to the barcode printed.
