Parameters

• station
  The printer station to be used. Possible values are defined by the PrinterStation enumeration. Valid values are PrinterStation.Receipt or PrinterStation.Slip.

• data
  Character string to be bar-coded.

• symbology
  Bar code symbol type to use. Possible values are defined by the BarCodeSymbology enumeration.

• height
  Bar code height. Expressed in the unit of measure indicated by the MapMode property.

• width
  Bar code width. Expressed in the unit of measure indicated by the MapMode property.

• alignment
  Placement of the bar code. For possible values, see Remarks in this topic.

• textPosition
  Placement of the readable character string. Possible values are defined by the BarCodeTextPosition enumeration.

Remarks

The alignment parameter values are as follows:

PrintBarCode is performed synchronously if AsyncMode is FALSE, and asynchronously if AsyncMode is true.

If the RotateSpecial property indicates that the bar code is to be rotated, then perform the rotation. The height, width, and textPosition parameters are applied to the bar code before the rotation. For example, if the bar code text position is specified as Below and the bar code is rotated left, the text will appear on the paper to the right side of the bar code.

Before it calls this method, the application must open, claim, and enable the device.

PrintBarCode may throw a PosControlException with the following ErrorCodes:
