Emails printing with VERY small font

If your email font is easy to read on the computer but prints out very small and you want it to print out larger, try this: when the email is open in Mail, hold down the Command key and tap the plus sign (+) only once. This enlarges the email font size for printing purposes. Tap the plus sign again if you want the font to be even larger. After printing, close that email in Mail and the font will return to its original size.
