Convert PGM to PCL

The Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.

The PCL file extension, Printer Command Language, is a page description language developed by Hewlett-Packard (HP) in the 1980s. It is used to control printer features and describe the layout of text and graphics on a printed page. PCL files contain commands that instruct the printer on how to print the document, including details like size, layout, and resolution. Initially designed for HP's inkjet and dot matrix printers, PCL has evolved to support various printer types, including laser printers. Its simplicity and efficiency have made it a widely adopted standard in the printing industry.
