Classification
There are two main types of printer languages: one is page description language (PDL), and the other is embedded language (Escape code language). The representative of page description language and embedded language are Adobe's postscript language (referred to as ps language) and HP's PCL language respectively. They are two laser printer languages that have become industry standards. When purchasing a laser printer, users should pay enough attention to the print processing language supported by the printer, and try to buy a laser printer that supports the latest version of the PCL language and PostScript language.
The printer control language directly affects the size of the printed file and the amount of content to be downloaded. An efficient control language can reduce the file size and download time, and increase the speed of formatting ordinary text into printed text. There are three control languages: PS, PCL, and GDI; printer controller, which is an important factor that affects the printing speed, it mainly affects the process that the printer transmits the processed received print job to the print engine for printing.
