PrepareToPrint Method

Description Prepares a print job for printing by initializing the printer device content, filling the document information and calling the StartDoc Windows API command.

NOTE: This method doesn’t actually print an image it just prepares the printing.
Next, for each image that should be printed, the developer must load the image and then call the PrintDIBPage method.  After calling the PrintDIBPage method, the developer must call the DropDIB method for the image if they no longer need the image.  Once all of the images have been printed, the developer must call the EndPrint method.  The psuedocode below demonstrates how several images can be print

1. PrepareToPrint

2. While some condition (for example from 1 to number of pages)

2.a. LoadImage
2.b. PrintDIBPage
2.c. DropDIB

3. End While
4. EndPrint
