・ About UPC-E barcode printing
This printer compresses the 11- or 12-digit data entered to 8-digit data by using the zero
suppression method of UPC-E standard. The following is an example of data compression
using zero suppression method.
Ex: Set the original code to be "0-ABCDE-VWXYZ" (11 digits). Printable patterns are as
follows:
1) When all V through Y are"0"
"0-ABCDE-0000Z": Denotes "ABCDEZ", where Z is any of 5 through 9.
2) When E and VWXY are all "0"
"0-ABCD0-0000Z": Denotes "ABCDZ4". The last 4 indicates that A and D of manufacturer
code is not "0".
3) When DE and VWX are "0"
"0-ABC00-000YZ": Denotes “ABCYZ3". The last 3 indicates that A and C are not "0" but
ABC is a number of 3 digits.
4) When DE and VW are "0" and C is "0", "1", or "2":
① When C = "0": "0-AB000-00XYZ" -> "ABXYZ0"
② When C = "1": "0-AB100-00XYZ" -> "ABXYZ1"
③ When C = "2": "0-AB200-00XYZ" -> "ABXYZ2"
The check digit is automatically calculated in the printer. When a condition other than the
above is specified and executed, error (OPOS_E_ILLEGAL) is returned because the printer
cannot print due to its specification requirement.
・ About rotating printing of symbol
Available rotating direction is 0° and 180° (all models).
RotatePrint Method
Print size changes dynamically up to the value of RecSidewaysMaxChars depending on the print
data. Rotate print in NV bit image mode is not supported. For NV bit image mode, refer to
“SetBitmap Method/ESC|#B Escape Sequence in 2.6 POS Printer Service Object and Precautions
