Well I can confirm it works... that may not be much of a surprise to those well versed in linux but it was a bit of a surprise to me.....
Up to three printers connect via USB to the Pi Zero which is connected to the network via either ethernet or wifi (or both), and if your printers are mega2560 based they are powered through just the USB connection so no over stressed on-board regulators (cut the Vin pin off the RAMPS/Mega connection) and the bonus of graphics displays you can see! No more USB cable issues or prints disturbed by other USB shenanigans... Orange Pi Zero 256Mb + expansion board under $15 (Banggood). ARMBIAN 5.25 stable Debian GNU/Linux 8 (jessie) 3.4.113-sun8i.
