Output Resolution• Pixels Per InchThe number of pixels that your printer will distribute over each linear inch of paper. Adjustable in your image editing software. This is how you set the size of your print. Printer Resolution• Dots Per InchThe number of dots of ink that your printer puts down on each linear inch of paper. This is usually a fixed characteristic of your printer. The printer driver will figure out how many dots to put down for each pixel. |
