All files from the web or just this one?
Have you tried printing the same file from another browser?
Is that an 8.5x11 in piece of paper?
What I'm seeing.....
Formatting issue or something physically wrong with the printer. Suspect formatting since you haven't said other docs print the same way.
Same thing happens if I print from email in Firefox or Chrome on mac, or print from a web page.
Same thing happens if I print from a PDF file opened with either Preview or PDF Expert on mac.
Same thing happens if I print from a text file in TextEdit.
Does not seem to occur as badly when I print a file from Pages, Apple's word processing program.
Yes, 8.5" X11".
