scope of use
The B series adopts ISO size, excluding Japanese JIS B series; excluding printers that cannot print the margins.
The higher the DPI, will the actual size of the paper become larger?
Not. The millimeters of the same paper are fixed, and the DPI changes the corresponding number of pixels. For example, the longitudinal direction of A4 is 210×297 mm, and 300dpi corresponds to about 2480×3508 pixels; the actual printing also needs to check the zoom and printer margins.
