what is dpi in printing

DPI stands for Dots Per Inch, which refers to the number of ink droplets a printer produces per inch while printing an image. It is an important measurement for photographers and designers, as it determines the quality of a printed asset, such as a poster, brochure, or magazine. The higher the DPI, the more ink droplets are tightly bunched together, making the image look crisp and high-quality. DPI is also used for scanner quality, meaning the number of points of data the scanner and computer pick up from the image. The higher the DPI, the larger the file size will be, as each dot or pixel requires more storage space. The standard DPI for most printers is at least 300 DPI or 300 PPI (Pixels Per Inch) . However, larger images may require an even higher resolution. When it comes to thermal label printers, 203 DPI is standard, but there are higher DPI printers, such as 300 DPI and 600 DPI printers. The higher the DPI, the clearer and crisper the print will be. The DPI value can be arbitrary, but it is recommended to use 300 DPI as a benchmark for printing high-quality images.
