6.5 Example WinCE Application – Escape Commands Version
The following code sample describes an example WinCE application that will generate some simple
output on the printer. The application assumes that a Bluetooth connection has been established
between the handheld and the printer. The application therefore prints to a (virtual) serial port.
The application is available as part of the documentation pack, and is provided in source and
compiled form. A suitable project file is also supplied to enable the code to be compiled using
Microsoft Embedded Visual C 4.0 (eVC4). eVC4 is available for free download from Microsoft's
internet site.
