Creating an Application That Lets You Print Wirelessly
The CV30 does not ship with an application that lets you print
wirelessly. You must create an application that opens the wireless
printing COM port on the CV30. For help, see the Bluetooth
Resource Kit.
The Wireless Printing applet is available from Start > Settings.
The applet separates the task of wireless printing setup from
other Bluetooth management tasks.
The Wireless Printing applet uses the concept of a “current
wireless printer.” The CV30 connects to the current wireless
printer when your application opens the wireless printing COM
port on the CV30. If there is no current wireless printer selected
on your CV30, there is no wireless printing COM port registered
on your CV30. You must select a current wireless printer on your
CV30, as described in the next section.
The Wireless Printing applet performs these tasks on the CV30:
• Helps you select the current wireless printer
• Stores the current wireless printer in the registry
• Registers/deregisters the wireless printing COM port
• Stores the wireless printing COM port in the registry as the
WPort
Specifically, the current wireless printer is registered and
deregistered on Bluetooth stack load/unload. If you select a
different current wireless printer, the existing wireless printing
COM port is deregistered and the new one is registered instead.
The Wireless Printing applet uses the Bluetooth COM Port
Control to handle COM port registration/deregistration.
Selecting the Current Wireless Printer on the CV30
By default, there is no current wireless printer selected on the
CV30.
There are three ways to select the current wireless printer:
• Discovering the printer using Bluetooth device discovery
• Manually entering the printer’s Bluetooth device address
• Choosing the printer from a list of previously discovered
printers
