I am stuck in solving the problem given below:

We are sending a page for printing to a printer with 500 dpi. the page size is 300*500 pixels. if each pixel is 20 bit then how much memory this would take in memory?

If anyone can solve this problem please reply soon. Thanks!

  • Hi there and welcome to the site. I have a hard time understanding your question. Maybe you could explain why you need to know this? The printer's dpi shouldn't really matter in this case. Do you perhaps mean that the resolution of the image is 500 ppi? An image with a width of 500 px printed at 500 ppi will only be 1 inch wide. Is that really the case?

  • Sir! actually, the question is related to HCI.

(300*500) pixels * 20bit/pixel = 3000000 bits. At 8 bits per byte that is 375 kb. The DPI is, as almost always, a red herring.
