Which printing language is commonly utilized for image printing?

The correct answer is Postscript, which is a powerful page description language used primarily for printing text and images. It allows for the precise control of graphical content and is widely employed in desktop publishing and the printing industry. Postscript describes the appearance of a printed page in a way that can be interpreted by printers to produce high-quality output. It includes detailed specifications for images, vector graphics, and text, making it an ideal choice for scenarios that require complex layouts and precise image rendering.

In contrast, other options serve different purposes. EMI (which might refer to a specialized data exchange format) is not commonly recognized as a standard printing language for images. PCL (Printer Command Language) is often used in laser printers, but it is more focused on text than on complex image handling. TWAIN is an interoperability standard that facilitates communication between software applications and image acquisition devices (like scanners) but is not a printing language itself. Thus, Postscript stands out as the most appropriate choice for image printing due to its advanced capabilities in handling graphical content.
