There is a bug in later versions of Adobe Acrobat. If Print as Image is greyed out, you may need to open File->Document Properties->Fonts and try clicking on several different random options. The print dialog should then offer "Print as Image" as an option. (This actually DOES seem to work. Any complaints should be directed at Adobe.)
