automatic command:
hanging screen: there is also a precision index called line resolution, abbreviated as: lpi
lpi: is the number of screen lines per inch of the screen used for printing images. That is, the
number of network cables.
The more the screen lines, the denser the dots, the richer and more delicate the printed matter.
Line resolution:
the main parameter to measure printing accuracy
Resolution:
Dot Resolution: DPI [unit to measure output accuracy]
means the number of ink dots per inch produced by the printer / the number of display dots per inch of the display output device. Generally speaking, it is the accuracy of the output device.
The higher the dpi of the printer High, the clearer the printed image, the finer it is.
Conditions:
-The resolution of the picture itself should be high
-the quality of the paper should be better
Printing high dpi requires high ppi and high-quality paper.
Common screen physical dpi is mostly 96
ppi: measure the accuracy of the equipment
