Firefox 8 & 10 on a MAC 10.6 with Brother MFC-7840W: When printing a webpage the printout has 1 inch margins left & right causing some screens that have data all across the screen to actually print left side followed by right side (frames?).
What you get is NOT the screen print you wanted. There appears to be nowhere that margins can be set for the Brother printer. The printing works fine in Safari, which has smaller margins. I think the basic problem are overly wide margins, but how can they be changed?

Look especially at these sections of the article: Prints to a small portion of the page and Does not print entire page content.
I tried all those options and nothing changed. Note: these appear to be fixes for the PC version, I'm on a MAC.
Not really. The probable solutions apply to Mac as well. As an alterntive, if you could visit this article, the instructions should show you steps specifically for Macs: Fix printing problems in Firefox.
