7 WinCE Printer Driver Programming
The Pro60 is supplied with a suitable driver for WinCE. This driver is presently available for
devices based upon the ARM processor.
Access to the printer is available to a programmer via a dll that must be present on the machine.
This dll is invoked by the following code and is further illustrated in the example application
described later in this document.
PrinterDC = CreateDC(L"Pro60_ArmI.dll", NULL, L"COM7:", &DeviceMode);
7.1 Example WinCE Application – Printer Driver Version
The following code samples describe 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. It
exercises some basic GDI functionality by drawing some text and some basic line graphics together
