Windows 7: Getting one printer to print from two computers

I have set up two Windows 7 computers,- (A) & (B) (A) has the printer attached. What is the easiest way to enable the printer to print from System B

Share the printer on computer A

Then on computer B go to networking and find the shared printer and print to it

There may be some differing details depending on if you are home networking, workgroup networking or domain networking though. Also some more steps if the machines were different OSes (I.e one XP and one 7)

Is it a wireless or wired printer?

if its connected to (A) it'll be wired, as if its wireless it would be a shared printer already

good way to print from 2 PC's only thing is the fact that pc (A) has to be on to use it.

Yup :/

If the printer has two inputs or is networkable those are other options. Personally I have a house server that is the only computer that is always on with my two printers connected to it...

You know, there /may/ be USB A/B switches like we used to use for serial and parallel ports back on the OLD days... try googling for it.
