I found this on HP Support forums and I quote<br />
&quot;Communication error--job is corrupted. Power down, remove Jet Direct and cold reset (hold down GO button while powering up). Reinstall Jet Direct (DO NOT reconnect e-net cable), power up and run a self test from the printer'd config menu. If this prints fine, clear the spooler and start to run some tests from the server. If all is well, you will have to enable driver auditing to check which job is wrecking the printer.&quot; <br />
Hope this helps fix your problem.

This printer keeps getting the Cycle Power error message (About once a day). Every time I turn it off and then on again, it works fine. It has 96 MB memory. It is an older printer, and it is used frequently. It seems to happen most when we send multiple print jobs. Any ideas?

A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.
