Positioning and scaling images

You can adjust the position and scale of an image and preview how the image will be printed on the selected paper using the Print with Preview command. The shaded border at the edge of the paper represents the margins of the selected paper; the printable area is white.
The base output size of an image is determined by the document size settings in the Image Size dialog box. (See Changing image size and resolution.) Scaling an image in the Print with Preview dialog box changes the size and resolution of the printed image only. For example, if you scale a 72-ppi image to 50% in the Print with Preview dialog box, the image will print at 144 ppi; however, the document size settings in the Image Size dialog box will not change.
Many printer drivers, such as AdobePS and LaserWriter, provide a scaling option in the Page Setup dialog box. This scaling affects everything on the page, including the size of all page marks such as crop marks and captions, whereas the scaling percentage provided by the Print with Preview command affects only the size of the printed image (and not the size of page marks).
Important: The Print with Preview command may not reflect accurate values for Scale, Height, and Width if you set a scaling percentage in the Page Setup dialog box. To avoid inaccurate scaling, specify scaling using the Print with Preview command rather than the Page Setup command; do not enter a scaling percentage in both dialog boxes.

To reposition an image on the paper:

Choose File > Print with Preview, and do one of the following:
• Select the Center Image option to center the image in the printable area.
• Deselect the Center Image option and then enter values for Top and Left to position the image numerically.
• Deselect the Center Image option and then drag the image in the preview area.

To scale the print size of an image:

Choose File > Print with Preview, and do one of the following:
• Click Scale to Fit Media to fit the image within the printable area of the selected paper.
• Enter values for Height and Width to rescale the image numerically.
• Select Show Bounding Box, and drag a bounding box handle in the preview area to achieve the desired scale.
