Guacamole emulates a printer, exposes that emulated printer over the RDP connection to the RDP server, and filters received print data through GhostScript to generate a PDF. The PDF data is streamed over the Guacamole connection using the file transfer mechanisms built into the Guacamole protocol. > 1.

If you are seeing such an issue, it must be something outside Guacamole causing that behavior, such as a proxy in front of Guacamole or a limitation of the filesystem storing the uploaded files. Guacamole's filename limits depend on the protocol in use: 2048 bytes for SFTP paths, and 4096 bytes for RDP paths. No part of Guacamole uses FTP. - Mike
