[FIX] hw_escpos: cashdrawer doesn't open
With some escpos printers the cash drawer did still not open after
previous fixes. One of the problemetic printers is the Epson TM-m30.
This fix will check the status of the drawer and try to open it up to 5
times. The fix is successfully tested with the TM-m30.
