CUPS offers a transportable print layer intended for Unix-based OS, creating a straightforward printing experience for users.
One of the best things about CUPS is that it provides the System V and Berkeley command line interfaces, making it easy for users to navigate and use. It uses the Internet Printing Protocol ("IPP") to manage print jobs and queues, which streamlines the printing process and ensures smooth performance.
Another advantage of CUPS is that it supports different protocols such as the Line Printer Daemon (LPD) Server Message Block (SMB), and AppSocket (a.k.a. JetDirect). Though these protocols have reduced functionality, it's still a great feature that adds to the software's versatility.
CUPS improves the printing experience by adding network printer browsing and PostScript Printer Description ("PPD") based printing options to support real-world printing under UNIX. It also includes an image file RIP, which means users can print image files to non-PostScript printers. Additionally, a customized version of GNU Ghostscript 7.05 for CUPS called ESP Ghostscript is available separately to support printing of PostScript files within the CUPS driver framework.
Lastly, CUPS includes sample drivers for Dymo, EPSON, HP, and OKIDATA printers. These filters use the aforementioned features and greatly improve the printing quality of the printers while still utilizing the CUPS framework.
Overall, CUPS is a must-have software for Unix-based operating systems that provides an excellent printing experience. CUPS provides a multitude of features that make printing a breeze and the implementation of different protocols shows the versatility of the software.
