           Summary: fonts reloaded for each page (performance issue)
           Product: Ghostscript
           Version: 8.61
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P4
         Component: Font API
        AssignedTo: support at artifex.com
        ReportedBy: f.kintzel at internet-access.de

When processing the attached file (no_embed.pdf) with a custom output device, GS
reloads fonts for every page. The same happens when using the nullpage-device. 

It's not really a bug but I'd like to circumvent this for performance reasons. 

The PDF uses 2 fonts (TrueType) that are not embedded.

Only entrys in the fontmap are:
/F0 /ArialMT ;
/F1 /TimesNewRomanPS-BoldMT ;

Fontpath is c:\windows\fonts

The printout is:
Processing pages 1 through 3.
