added a calibration square for printing - there is a default
setting on the Settings screen and a checkbox to add a calibration square to your pattern files on the Save and Print screens. The calibration square will
appear to the right of the patterns. You will be able to move it on the Print screen just as you do any pattern and place it where you wish.
