Scaling an image in the Print Preview dialog box changes the size and resolution of the printed image (the file size of the image doesn’t change).
Choose an option from the Print Size menu.
For Scaled Print Size, enter values for Height and Width to rescale the image numerically. The dimensions are constrained, meaning changing one dimension proportionately changes the other dimension. If the Scale, Height, and Width boxes aren’t available, deselect Crop To Fit Print Proportions.
Make sure that Show Bounding Box is selected, and drag a bounding box handle in the preview area to the scale you want.
Type a percentage in the Scale text box.
