How do I open the cash drawer from .Net application?


Using the special printer font function of the driver to open the cash drawer on .Net application will not work because the printer font is not supported by .Net Framework. Instead, use the printer driver function to automatically open the cash drawer. The details of this function are detailed in the driver manual.

Also there is another way to send the print data directly from aplication software through Windows driver.
You can get the sample program from Microsoft site.
