Question

what is the highest dost per inch DPI can print drawing​

Answer 1

For most artwork, 300 dpi is preferred. Most printers produce excellent output from images set at 300 ppi.

You can use 150 dpi for large prints because the difference in print quality is not very noticeable on large pieces when you look at the prints from a distance.

Output device resolutions vary, depending on the type of press and paper used. In general, a photograph is output at a crisp 150 lpi if printed on glossy magazine stock, and at 85 lpi if printed on newspaper stock.
