Need a solution to decently print web pages

I just switched from Windows to Mac and still haven't found a good way to print web pages on paper or as pdf. Specifically, I am having troubles with header / footer margins and file sizes.

When using Firefox on Windows I can adjust print scale (in %) and margins so that any page I print looks good. pdf file size for a test page with a picture was 200 KB.

On OSX 10.7 I am having the following issues:

Safari:
Space between header / footer and page top / bottom is much too large. There seems to be no way of changing it.
pdf file size for the same page is 435 KB, which is acceptable.

Chrome:
pdf file size is much too large: 1.6 MB!
Header / footer margins better than Safari but still too large and not customizable.
No page scaling is possible.

Firefox:
There is no print preview!
pdf file size much too large: 1.6 MB
Header / footer margins: Same problem as with Safari

So is there a solution that lets me
- adjust print scale
- and adjust header / footer margins
- and create small pdf files?

Not really, no.

In theory I should be able to set print margins in Safari. There's an option to define custom paper sizes. In that menu you can set a "non-printable area". But the settings I make there have no effect at all. Does anybody know if this is a bug?
