Simplest way to Change network printer to print Black and white by default

In an Enterprise, color print is expensive. Users often do not care whether the print is color or black and white. They just print. And to save cost, you want users to be offered black and white printing by default?
This is how you do it if your printer is a network printer and runs through a print server.
1. Login to your print server
2. Open 'Print Management'
3. Click on Printers
4. Right Click on the printer you want to set and click on 'Properties'
5. Go to 'Advanced'
6. 'Printing Defaults' and change 'Output Color" to 'Black and White'
7. Click 'OK' 'OK'

Now on next logon users will find the printer's Output color set to 'Black and White'
NOTE: There is another way to do this via group policy but this is the simplest way.
