The printer distribution option can be valuable, especially for a small initiative network. It can keep your costs down by lessening the number of printer devices you need to acquisition. Below is a guide on how to share a printer, which is physically devoted to a PC featuring Mac OS X 10.6 or Snow Leopard, with a PC running on Windows 7.According to Tsgpc Help
How to Share a Printer Hooked Up to Mac with Windows 7 PC.

For Mac printer sharing, you also require the below things:

•A working wired or wireless Ethernet system
•A common workgroup for Mac and other PCs on the system

The printer distribution process involves three steps – (a) Ensuring Mac and other schemes are on a common configured workgroup; (b) Turning on Printer Sharing in Mac OS; and (c) Adding a joining to Windows 7 PC’s network printer.

Configure the Common Workgroup Name

WORKGROUP is the default name of this feature in Windows 7. If you have not made changes to it on Windows PCs linked to the network, then you are good to go since the Mac OS also generates the same name for linking to the systems with the other OS. Yet in case you have renamed WORKGROUP in Windows, then arrange the same name in Mac OS too.

Turn on Printer Sharing in Mac OS

For this, you need to have a printer previously connected to Mac PC that you want to portion on the network.
•Launch Organization Preferences by choosing it from the Apple menu.
•In the window that pops up next, choose Distribution preferences after the Internet and Networking
•The pane that you chose has a list of facilities that you can run on Mac. Put a tick following to Printer Distribution in the said list.
•Once it is enabled, a list of existing printers for sharing appears. Put a tick next to the printer that you need to part.
•Exit System Preferences.
