Most printers have and on-line LED and button or the equivalent.
Most printers will beep once or twice during or after initialization. If it beeps more than that or beeps constantly, the poor thing is either hurt or trying to tell you something is wrong. Look in the manual or go to the web site to learn what it is saying. Unfortunately, beep code documentation can be hard to find, the beep you hear may not listed, or the meaning of the beep is nebulous. Most, printers will beep when out of paper or out of ink and those are the most common causes for a printer turning into a road runner.
