    Printing Note: If you're printing pages from this website and find that the right side is cut off, try this: With older printers, you could choose the "landscape" (horizontal) setting rather than the "portrait" (vertical) setting when printing. But most newer printers let you scale down web pages before you print. For example, if you have an HP laser printer, when you choose "Print" from the menu, you can then choose "Preferences," where under the "Effects" tab you can change the 100% setting to, say, 95%. You may also see a "ZoomSmart" feature that lets you choose "scale to fit."
