As soon as I hooked the printer into the computer, Ubuntu said that it was installed. So, I tried printing, and a paper prints saying "** Unable to open the initial device, quitting."

Then I run a diagnostic on the printer, and it comes up with nothing, except for a troubleshoot document, in which I don't understand at all. (Will post results if asked, they're just extremely long).

The next thing I do is Google it, and I find a link to download and install the drivers for it, so I follow the instructions: http://hplipopensource.com/hplip-web/install/install/index.html

I type what's in the first step, then hit enter.

Instead of saying what it's suppose to (in the 2nd picture on the link), it says: "sh: Can't open hplip-3.11.10.run". That's all it says. I need help! Any suggestions would be extremely appreciated!
