Windows 10 and Dell 1600 MFP Printer

If you have an old Dell printer that has no Windows 10 drivers available but has a network interface, try installing the printer via TCP/IP and using the Windows 7 x64 drivers.  If you don't have a network switch, you should be able to use a crossover cable from PC to printer.

I had given up on making it work from all the posts on the internet.  I didn't really care if I used it via USB or not, just wanted something to print from that was reliable.  I had spent $80 on ink for a free HP inkjet printer which ended up drying out and was ready to toss that thing.

I only came across this because I used a Macbook for my kid's remote school learning and surprised it found the printer.   After that, I tried installing the Bonjour service to no avail and then installed it via TCP/IP and was able to get it to print.  

This was a printer from a company I use to work for 12+ years ago that went out of business and still has 21% toner left. Rather than throwing something that still has plenty of life, it is usable again!  The inkjet however will be given away or disposed of...
