Resolution:
INTRODUCTION
==========
This program will demonstrate how to allow a user to select a font and style for printing using the Windows SDK function ChooseFont in conjunction with the Net Express PC_PRINTER routines.
This function allows you to present a list of available fonts to the user for selection. This can also be done by setting the appropriate printer-flag when using the PC_PRINTER_OPEN call but the ChooseFont function is more powerful. It allows you to present a list of fonts based on certain criteria such as only Truetype, only fixed fonts etc.
The criteria flags can be found in the CFDEFINE.CPY copy file.
This example will use the selected font to output various text lines to the printer. The lines will be printed in differing point sizes and text attributes such as bold and italics etc., if they are available for the selected font.
