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.

First off, you should actually install a distro because it is quite a different experience using one that you installed and customized yourself. The middle click issue can be fixed by going to about:config and setting middlemouse.contentLoadURL to "false". To see if your printer is compatible, you can try looking for it at http://www.linuxprinting.org/printer_list.cgi or by searching on search engines.
