Excerpt: I did not want to load any software on because 2 of my computers are Editing Computers that I do not add much onto.
I like that loading software was not needed to have this function well.
When I began my search for this printer switch I did not expect to find one this nice.
IOGEAR GUB431 4-Port USB 2.0 Automatic Printer Switch
Ben B., Newegg
19 January 2013
Summary: Fast Shipping from Newegg.com.
Pros: 4 Computers to Laser Printer/Scanner unit which doesn't have NIC interface, and simply this device works. I was bit hesitant since it is made by IOGEAR (from bad experience), this time it's fine. OS Running: Windows7 64bit, Mac OSX ML
Cons: This item simply stopped being recognized by my system (Windows 7 Ultimate, 64 bit, on the desktop and Windows 7 Home Premium, 64 bit, on the laptop) within two weeks of being installed. Re-installation of software failed. The hub simply stopped being recognized by the device manager. No printing...
Summary: I had a rather unusual situation where networking the printer was simply not an option. I was able to locally connect 1 printer to 3 different computers and this switch\software combo handled it perfectly. Couldn't be happier.
