The RFPrint method allows you to print data directly to an RF device's display over a wireless network.
VB
bStatus = object.RFPrint (nColumn, nRow, pszMessage, nMode)
VC++
HRESULT hr = object->RFPrint(short nColumn, short nRow, LPCTSTR pszMessage, short nMode, BOOL *bStatus);

bStatus |
The status of the function returned as Boolean True or False values. Use the RFGetLastError method to return the error value. |
