This occurs when the page uses frames.
For best printing results, click on the block of text that you are trying to print immediately before printing. Many websites have these major elements, each of which could be a frame:
- A site identification area, or banner, across the top of the page.
- A table of contents, or navigation links, in a column on the right or left side.
- A central text window in the middle, which shows the main content.
Update to Mac OS X 10.3.6 or later to resolve the issue.
As an immediate workaround, prior to updating, you can click the text in the primary window immediately before printing. This tells Safari that you are focused on the main content frame.
