IsBatteryOKToPrint
Description
Checks if the printer’s LiIon battery (located in the handle) is charged
enough to allow printing. Check the battery level before any printing

during printing. If you use it during printing, the return
value is not accurate.

Return Values
FALSE

if (!rPrint.IsBatteryOKToPrint) // Not OK to Print
MessageBox.Show("Low Battery", "Battery Check");
}

Dim rPrint As New Print ' Instantiate class
rPrint.ClearError() ' Clear any errors
