As of 2019 the supplied printer-drivers support a total of 2,867 HP printer models; many of these for low-end models are free and open-source (FOSS), licensed under MIT, BSD, and GPL licenses, but others require proprietary binary blobs ("plug-ins"). The project intends that HPLIP work in combination with CUPS and SANE to perform printing and scanning respectively.
