BT Printing Symbol

I'm printing via the BTExplorer to a Bluetooth printer (Zebra QL220) from an
Symbol MC70. The printer MUST be on or the application will not print to
the printer. Even if the printer is turned on after the first print
attempted, the application has to be turned off and restarted with the
printer on for any BT printing to take place. I'm basically just sending
serial stream to the BTEplorer app.
Using Dick Grier's SerialCF control for serail output.
Is there a workaround that would even allow the printer to be turned on via
If g_blnBlueToothPrinting = True Then
Try
With SerialPort
.RTSEnable = True
.DTREnable = True

.CommPort = 9
.Output(txtTextToPrint)
End With

The .RTSEnable = True
.DTREnable = True
lines tend to activate the wired printer but do nothing to activate an
associated BT connection.
How can I make this pairing more bulletproof?
 
Harry,

I don't know how to make the pairing more bullet proof, but we are using
Bluetooth printing in the field successfully. If I can't open a serial port,
I put up a MessageBox indicating that I can't print, and all my printing can
be redone at a later time if necessary from a menu option.
 
Thanks Ginny
Suppose I need to do more debugging using the Bluetooth printer in various
states. Got the wired working so well - now to bulletproof the BT!!

thanks
Harry
