Parameters

  • type

Remarks

MarkFeed is performed synchronously if the AsyncMode property is set to FALSE, and asynchronously if AsyncMode is true.

If type is PrinterMarkFeeds.Takeup, the printer will feed the mark-sensed paper so that the present form is positioned to be manually removed by the operator.

If type is PrinterMarkFeeds.Cutter, the printer will feed the mark-sensed paper so that the present form is positioned to be cut off by the auto cutter. This will usually be followed by a call to the CutPaper method.

If type is PrinterMarkFeeds.CurrentTopOfForm, the printer will feed the mark-sensed paper (backward if it is necessary) so that the print head points to the top of the present form.

If type is PrinterMarkFeeds.NextTopOfForm, the printer will feed the mark-sensed paper so that the print head points to the top of the next form.

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

MarkFeed may throw a PosControlException with the following ErrorCodes:
