Blurred font in PDF printing

[sunafei]

I use the latest version. The font in PDF is imitation Song-Dynasty-style typeface. It prints normally with PDF reader and blurs with pdfjs.

You can set the PRINT_RESOLUTION in web/viewer.js in the function renderPage() to 600 or even 900. Thats still not the perfect print but it is at least acceptable.

I can confirm that printing text produces results at very poor resolution. Printing the same target files from a native viewer on the same system shows no similar problem.
