This device was purchased for use with an HP USB laser printer and a workgroup of MacBook Pros running OS-X Mavericks.  It's not working well.  Works for a while... Then stops and reports the printer is busy.  Will not print until power cycle the device.  It's already running the latest firmware available.  Been in touch with tech support.  They did not have any suggestions.  It may work OK with a PC... But if you own a Mac... Look elsewhere.
