ClaimDevice Method

No identical serial port (COM*) specified by the Windows driver is not usable in the connection of serial interface. When this method is executed in this connection, “OPOS_E_TIMEOUT” is returned.

PrintBarCode Method/RotateSpecial

・Supported barcodes

PTR_BCS_UPCA, PTR_BCS_UPCE, PTR_BCS_EAN8, PTR_BCS_JAN8, PTR_BCS_EAN13,

PTR_BCS_JAN13, PTR_BCS_ITF, PTR_BCS_CODABAR, PTR_BCS_CODE39, PTR_BCS_CODE93, PTR_BCS_CODE128, PTR_BCS_UPCA, PTR_BCS_UPCE

・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":

①When C = "0": "0-AB000-00XYZ" -> "ABXYZ0"

②When C = "1": "0-AB100-00XYZ" -> "ABXYZ1"

③When 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”.
