Contact A&E's digital content editor, Julia Schroeder, if you're interested in contributing and for an opportunity to be featured in our daily eNewsletter. 

Pulses per inch refers to the number of times a laser beam will pulse in a one-inch area. It controls quality of an image for the horizontal motion. In general, the PPI should match the image's DPI. See DPI (Dots Per Inch).
