Paper Tape Calculator
If you are used to the simple virtual calculator, the printing calculator works almost the same way.
Some of the internal logic has been updated. Refer to the instuctions for the simple virtual calculator, available here.
The printing area is scrollable. If you need to scroll up or down click on the printing area (the white area on the left of the keyboard) and use your mouse wheel, the up and down arrow keys or the 'Page Up' / 'Page Down' keys.
The text in the printing area can be selected and copied to other applications (for example into notepad for printing, or into any other type of document).
On the printing calculator you can repeat multiple times the last operation by repeatedly pressing the 'equal' key. For example, for a countdown from 10, enter '10-1', then keep pressing '=' until the display shows 0.
