The following public methods are new in SP2.

Properties and methods	Description
LoadFromHDC Method	Loads printer device parameters from a passed GDI printer handle, using the Windows API GetDeviceCaps function. Syntax: LoadFromHDC(tiHDC) Return Values: string Parameters: tiHDC is the handle (an integer) to the printer from which the device parameters should be derived.
LoadFromStrings Method	Loads printer device parameters from string variables. Syntax: LoadFromHDC(tcExpr, tcTag2) Return Values: string Parameters: tcExpr is typically the contents of the EXPR memo field from the header record of an FRX with printer environment information saved. It provides DRIVER and DEVICE values. These are passed to the LoadDeviceInfo method as its first and second parameters. tcTag2 is typically the contents of the TAG2 memo field from the header record of an FRX with printer environment information saved. This is passed to the LoadDeviceInfo method as its third parameter.
