change a file from Dos to ext2

["Cristian Carnutu" <ccarnutu@hades.ro>]

Hi,

1)  I have a file named wabi2.2.tar. 
I made the command    tar -x wabi2.2.tar and nothing happens.
I think because it is a DOS file type. It was on a DOS floppy.
Which is the command to change it to a linux format ?

2)  How do I disable the printing queue? For the moment I don't need it

Best regards,
