I'm sure many of you print documents straight from the browser. Mozilla Firefox allows you to edit the printing options as well, as an ordinary text editor would do. The Firefox application is truly a multi-functional browser. :)
First of all, from the drop down menu in the top left corner of the browser, you can choose "File". Go File > Page setup...and you will get these two options:
In "Format & Options" you can choose orientation, portrait or landscape. You can scale or make it auto-adjust. If you want the background printed out (usually that's not necessary or useful) just check the box which says "Print background (colors & images)".
In "Margins & Header/Footer" you can adjust margins, as well as choose what you want or don't want in the headers and footers, really it's only your imagination which is the limit. :)
Now, as you see you have many of the same options as a regular text editor program as for example Open Office, Word and such. I can't tell you what your settings should be, that's your choice. :) For the next function, go to File > Print Preview...an you will get the following options:
If you look at the top tool bar, you got all your options at one place. :) You can really access most functions from Print Preview, and lay the finishing touch on your printout. Enjoy.
