Techniques are described for enabling printer redirection in virtual desktop environments that provides a font processing system including a session-based font cache subsystem. The system resolves any font mismatching issues that might arise in the context of printing on a virtual desktop from virtual desktop client devices in an optimized manner that reduces latency and generally improves performance during printer redirection. The session-based font cache is used to accelerate the font processing and to reduce the transmitted font data between the virtual desktop agent and the virtual desktop client in the context printer redirection.
