RupmPrinter

RupmPrinter is designed to be a multi-platform printer server & frontend application for SJTU Library Printing System.

It is a reversed version of the official UPMClient Windows driver from Unifound.

R as in Rust/Reverse/Rewrite.

It works as a Sockets Server, a PCL Interpreter and a Frontend Client on Windows/Linux/MacOS.

On Windows it can also work as a patch of the original client.

Usage

Windows

As a Patch

1. Rename RustPrinter.exe to UPMPrinter.exe
2. Replace C:\upmclient\UPMPrinter.exe with the new one.

As a Server

Unix-like Systems

1. Install CUPS (Usually preinstalled)
2. Register the printer (Please make sure port 6981 is available)

lpadmin -p RupmPrinter -E -v socket://127.0.0.1:6981 -m drv:///sample.drv/laserjet.ppd

Note: You can change the PPD file to other PCL5 compatible files.

3. Run the client
4. Choose RupmPrinter as target when printing
