How to control access to printers on an XP network

[Restek]

I've not really played around with windows networking much, but I've just ended up with 2 comps & so am looking at file & printer sharing. File sharing is all fine, but there's one thing which surprised me when sorting out printer sharing. If I browse comp 2 from comp 1, I can see all the printers installed on comp 2 - this is irrespective of whether they are explicitly shared or not. I can also print to them and alter their settings with no problems. So what exactly is the point of selecting the 'share this printer' radio button?

Both comps are running XP Pro, and I'm logging in as myself (admin) across the network (Guest user is disabled).

If you create another user account with regular user permissions (Not administrator) they should not be able to see the printer unless it has been shared.

By sharing the printer you can control access and configuration settings to your normal users. If you look at your printer security settings, by default the Admin has full access to it. Regardless if its been shared or not.
