Do you have any other program you can print from? Maybe MS Paint? Or Word. You can
manage the size more realistic in these programs.
In Paint, once you open your picture, click image on the toolbar, attributes. This
will give you the size, click image again, click stretch/skew, change the horizontal
and vertical percentages equally until you have the size you want.
This is not the best program to use for this, but it works.
