Linux Difficulties

Hello, right now, I'm posting from a Knoppix Live-CD distro.

Anyways, I'm trying to switch to Linux, however, I'm having trouble getting it to work rightly for me.

Firstly, I don't know if my printer will WORK with linux. I can't seem to be able to print stuff out atm. And I don't know if the Lexmark printer driver will work with say... a Ubuntu or Debian distro.

Next, this one is a bit of a nuisance, on Windows, with Firefox when I middle click, I can scroll down super fast on pages. Now, with Knoppix, right now, when I middle click on Firefox, I'm redirected to ad pages for software or some blog or something, which is strange.

Like, if I middle click on this page, I am sent to http://www.zizasoft.com/products/zsDuplicateHunter/index.shtml. I'm not sure if the people who designed the Knoppix distro mae money from shelling these ads in their Live-CD, or if it's just a glitch or a hidden feature or something. Either way, it makes me less anxious about switching to Linux.

when i installed firefox in windows i was kind of suprised that you _couldn't_ hit the middle mouse button to load urls :/

now i installed ubuntu on my laptop, and since it doesn't have a scroller thing on the mouse, i want to use the middle button for scrolling fast.

it'd be convenient if i could set it so like the middle mouse button scrolled fast, but the left and right mouse button together loaded urls.
