Previewing
FinePrint will display the actual pages of the print job, allowing a preview of the pages before they are printed. The scroll bar to the right of the page display view in the Layout tab can be used to scroll through the document. Pages and sheets can be zoomed by double-clicking the page in the previewr or by using the context menu by right clicking the pages.

Printing the selected sheet
Right click on the preview and select "Print sheet". This will print the currently displayed sheet.
