Printing pdf
If you cannot print out pdf files well, try the following
tips.
    - @: Adobe Acrobat, print option window. Printing level
        should be level 2. Maybe. I'm not sure.
 
    - @: Adobe Acrobat, print option window. Switch off
        "Optimizing by giving the printing speed the
        priority."
 
    - @: Printer property, detail option window. [Document
        option]-[PostScript option]-[PostScript output
        option]-[Optimize in order to reduce errors].
 
    - @: Adobe Acrobat, print option window. Switch on
        "Print as an image."
