You can try to disable the website fonts to see if that works.
It is possible that a font is specified that isn't working with that printer.

Tools > Options > Content : Fonts & Colors: Advanced > [ ] "Allow pages to choose their own fonts, instead of my selections above"

Don't forget to re-enable afterward.
