WINPRINT-SET-BKMODE enables you to set the background mode for printing. This is useful for adding watermark effect to prints.
By calling this op-code, the printing mode of the current print job is set accordingly. Note that if you have multiple print jobs, and you are not setting the current print job, WINPRINT-SET-JOB must be called prior to this op-code to target the correct print. A call to this function with no active print will be ignored, and a value that differs from those specified above will be ignored.
