Know your gear
The Canon MP11DX has the perfect combination of useful and sophisticated features for the busy professional. This desktop, two-color printing calculator incorporates profit margin calculation keys that allow you to calculate the selling price or discount, based on the cost and desired profit margin. Another time-saver is the tax feature. You can store a rate that you frequently use for fast and convenient access, eliminating many steps of your calculation. In addition, the built-in clock and calendar allows you to view the time and date on the display or print them out.
