The headers and footers are optional. In my Linux Firefox, if I go to the File menu, select the Print option, go to the "Options" tab, there's a whole "Header and Footer" section where you can set them to whatever you want, including "--blank--".
Details of this print dialog might, of course, depend on your GNOME version, your distribution, and the time of month, like everything on Linux.
Now the quality of the text is a separate issue; I haven't actually done any printing from a web browser on Linux in a few years, so I have no idea what that looks like nowadays.
