Use Legacy Printer From Windows 7

I have NEC SuperScript 870 laser printer connected to my Home PC. I was not able to print to this printer from my new HP dv6-1375dx Windows 7 laptop. My machines are connected via Hamachi. Here is what I did to get around the lack of NEC driver for Windows 7 (I found this tip here) –

1. Created a new printer (pointing to the same LPT port that is connected to NEC 870) on my Home PC using HP Laser Jet III driver.

2. Shared this new printer.

3. On the Windows 7 laptop, I dropped the document I wanted to print on this new printer. Voila !!!
