The best-known non-impact printers are the inkjet printer, of which several makes of low-cost color printers are an example, and the laser printer. The inkjet sprays ink from an ink cartridge at very close range to the paper as it rolls by.
Here is an easy way to find your draw length, simply stand upright with your hands stretched out (hold naturally, do not hyperextend) and measure your arm span from fingertip to fingertip. Take this measurement in inches and divide by 2.5. This will give a good working draw length for your bow.
Match your calculated draw length to the appropriate bow size in the chart to the left. NOTE: I always round the calculated draw length up to the nearest 1/2 inch for recurve bows. It is preferable to shoot a longer bow than one that might be too short. Go here to learn more about why determining your proper equipment is important in archery.
