Completed Work
Ensured all cups-filters filter functions work without PPD files, enabling them to operate purely with IPP job and printer attributes — critical for the CUPS 3.x PPD-less architecture.
Developed a GUI application for listing and managing available IPP Print/Scan services, supporting DNS-SD-advertised network service discovery.
Created a single, universal CUPS filter that calls sequences of filter functions internally, reducing the overhead of external process calls in filter chains.
Added printer setup tool support and initial scanning support to PAPPL, extending the framework to handle scanner hardware alongside printers.
Converted CUPS filters into reusable filter functions inside libcupsfilters, decoupling the printing pipeline from external executables.
