[Ophus Office Partner Mall] When evaluating printer products, you often come into contact with the word "PPM". "PPM" refers to the output speed per minute. How is this printing speed calculated? What is the standard for printing speed? Today, the editor will answer your questions.

Therefore, when selecting a printer, we must confirm with the seller that the PPM value indicated in the operation manual refers to What does it mean. Need to be reminded that the PPM value is only if you only print one page, you need to add the home page warm-up time.

Calculation. The latter can use the upgraded computer grades, supplemented by the high version of the application software, shortening the data transfer time to increase the output speed.
At present, in the inkjet printer market, the printing speed of ordinary products can reach 20ppm, and those high-priced, good-brand inkjet printers can print faster. For inkjet printers, it depends on the following factors: the size of the printer's cache (CacheSize), the interface of the data transfer, the size of the printhead, and the number of nozzles. The print speed of photo-quality printers is related to many factors, such as engine speed, processor frequency, whether it is equipped with a dedicated image processing chip, the number of internal data channels, the ability to process multiple images simultaneously, and the image printing technology used.
