2 Way AUTO Parallel Port A B Switch for Printers, Scanners. Use one Printer or Scanner with 2 Computers!! It Works Automatically, no Need to Turn a Switch!

I'm in the process of closing my medical practice, which has been running a DOS-Based (but wonderful) EMR. It will only print through a parallel port, and since I need to print from more than one computer, this A/B switch is perfect. Just like what you could buy in the 1990's.

DIDN'T WORK, SO I CONTACTED THE SUPPLIER AT THEIR TOLL FREE NUMBER, AND AFTER OVER 20 PRODUCT PROMO ANNOUNCEMENTS WITHOUT BEING ABLE TO SPEAK TO A PERSON, I HUNG UP. WOULD NEVER RECOMMEND ANYONE BUYING THIS PRODUCT. HOPEFULLY AMAZON WILL REFUND MY MONEY.

excellent, ordered on the 8th, delivery promised by 14~19, received on the 10th. dinosaur tech works great with new tech.

Very satisfied
