The print preview dialog provides several options for printing pictures:
Portrait or Landscape
This option allows you to control the layout of the entire sheet of paper. Changing this option can also sometimes make additional layout choices. You most likely need to choose this setting first, since the other settings are affected by this (FotoAlbum makes a best guess on the layout).
If you change the page layout to print Wallets or other multiple prints, then you often will need to change the portrait/landscape mode.
Page Layout Selection
Select the layout (which also controls how many re-prints will print). The options will change based upon the paper chosen for your printer. As you change the option, the preview will change to show the selection.
Crop to Fit
If the "Crop to Fit" option is checked, then your picture will be cropped to fit the proportions of the printout. This option works best if you are printing a picture to go inside a picture frame. You have to manually "move" each picture to the location you want to crop. You also have to do this for every separate print in the layout. The cursor changes shape as you move over each print to let you know what directions you can move the print.
To drag each print into location, merely move your cursor over the print and click and drag with the left mouse button. You will move it up/down or left/right depending on the proportions of the picture.
If the "Crop to Fit" option is not checked, then you do not have to position each print, but you will get a white border if the proportions of the print do not match the picture exactly. This works best if you are not trying to fit a picture frame and want to be sure you do not lose any picture details.
Zoom
The zoom option is only used to control the display of the preview dialog. It does NOT affect the final printout. By changing the value to a larger number, you will zoom in on the preview. This is helpful when setting the cropping position. Changing to a lower value will zoom out. The default value of "Best Fit" generally works best.
Printer Setup
The "Printer Setup" button allows you to change your printer. You should change your printer first before setting the other settings on this screen (the printer can affect the other options). You also can change the quality of the print and other printer specific options from here.
