To find the total area available for printing, we need to subtract the area of the margins from the total area of the pages.

The total area of the pages is given by the length multiplied by the width, which is 20 cm * 14 cm = 280 cm^2.

The area of the margins on each short side is 2.5 cm * 14 cm = 35 cm^2.

The area of the margins on each long side is 2 cm * 20 cm = 40 cm^2.

Since there are two short sides and two long sides, the total area of the margins is (35 cm^2 * 2) + (40 cm^2 * 2) = 70 cm^2 + 80 cm^2 = 150 cm^2.

Therefore, the total area available for printing is 280 cm^2 - 150 cm^2 = 130 cm^2. Answer: \boxed{130}.
