The screen shot below shows the basic previewer functions.

In addition to using the mouse to select pages to print (designated by the green check mark) or to skip (designated by the red cross), you can type in a list of pages to print. ODD will print all odd pages. 2-5,8 will print pages two through five and page 8.

You can click the print button to print all selected pages, or use Alt+P.  You can use Alt+1 to print the current page.

In addition to the plus and minus zoom buttons, you can left-click the preview area to zoom in or right-click to zoom out.
