Just improve the picture resolution and print resolution at the same time.

Pictures are usually adjusted to the right pixels:

1, printed on photographic paper, 72 pixels is also acceptable.

2, inkjet printing, 30 pixels will do.

3, photo paper printing, need 300 pixels.

4. The best resolution of laser printing is 150.

5. The best resolution of color inkjet printing is 200.

The resolution of a general laser printer is 600×600dpi.

The higher the resolution of the printer, the more accurate the output. However, not every printing requirement requires the highest precision printing. For text printing, 600dpi has achieved excellent line quality. However, in modern office, the types of printed documents are increasingly diversified, and more and more images, photos, CAD, GIS and other contents need to be printed with high precision. At this time, in addition to the printing load and printing speed, users must also carefully consider whether the printing quality of the printer can meet their own needs.

For photo printing, higher resolution means richer color levels and smoother halftone transition, which often requires a resolution above 1200dpi.
