During class last night, it seemed like everything we printed was coming out a bit bigger than we intended. After class I tracked this down to a setting in the CorelDraw print dialog. On the Layout tab, you can control “Image position and size” for the print. By default, it is set to “As in document”, so what you drew is what you get. You can also choose “Fit to page” or “Reposition images to”, and with the latter setting, you can set a scale factor, or even separate scale factors for horizontal and vertical. Somehow the scale factor got set to 1.16, which makes everything print 16% bigger than drawn.
This is a useful feature to know about. But please, if you use a feature like this, try to remember to set it back to the default before you go, to avoid causing problems for the next user.
