The API call is SetPrinter(); it's not a trivial undertaking to implement, though. I've been playing with implementing it using CLSHEAP to handle the PRINTER_INFO_2 strucutre, which contains a pointer to a DEVMODE strucutre, which controls basic printer setup parameters.

Since your concern is about a design-time tool, why not just use the Page Setup dialog under the File menu to do this, or access the dialog through the Shell.Application ControlPanelItem method to launch the Control Panel applet?
