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.
I'm looking into getting a bow, probably a recurve but definitely not a compound and allot of places sell them saying it's a 45# or 30# etc. and i'm not sure what my # is I know that my draw length is 28.6 and im about 165 pounds, not very muscular at all.
