About downloading language-specific fonts
Select the Download Asian fonts option in the Advanced Print Setup dialog box if you
want to print an Adobe PDF document with Asian fonts, but the fonts are not installed on
the printer or embedded in the document. (Embedded fonts are downloaded whether or
not this option is selected.) You can use this option with a PostScript Level 2 or higher
printer. In Adobe Reader, Asian fonts are installed on demand if you open a PDF
document containing them.
If Download Asian Fonts is not selected, the PDF document prints correctly only if the
referenced fonts are installed on the printer. If the printer has similar fonts, the printer
substitutes those. If there are no suitable fonts on the printer, Courier is used for the text.
If Download Asian Fonts does not produce the results you want, print the PDF document
as a bitmap image. Printing a document as an image may take longer than using a
substituted printer font.
Note: Some fonts cannot be downloaded to a printer, either because the font is a bitmap or
because font embedding is restricted in that document. In these cases, a substitute font is
used for printing, and the printed output may not match the screen display.
