' CLASS : clsPrintDialog
' PURPOSE : Show a dialog to select a printer and to set printer
' properties. Selected printer will be set to Printer object
' WITHOUT CHANGING DEFAULT PRINTER.
' Printer object could print to selected printer then.
' This class work like "MS Common Dialogs" ShowPrinter method,
' but it set Printer object without changing default printer.
' HELP : Look "MS Common Dialogs" OCX help, it applies also to this
' class. All Flags constants are supported.
' NOTE : Do you have found any bug or improvement ?
' Please let me know, that's why I'm sharing source code.
