Postage website Endicia recently announced the availability of printable postage sheets by DYMO. After registering for a free account on Endicia.com, users can use the self-adhesive label sheets to print U.S. Postal Service-approved postage from their PC or Mac using any printer. There is no monthly fee; users pay only for the stamps they print. Endicia's software determines the right amount of postage for packages based on weight, destination, and mail class. The printable postage sheets are available at Endicia.com for $7.90 for 10 sheets. They also are available at OfficeMax and Staples.com. A special roll version of DYMO stamps can be used with premium models of DYMO's LabelWriter printers.
