Standard photo resolution is 300 ppi. So with a 300 ppi image on a 600 dpi printer, each pixel would be reproduced by multiple tiny ink dots for smooth photographic quality. But higher printer dpi can‘t increase the available image ppi. A 200 ppi photo will still only contain 1/3 the pixels of a 300 ppi version, regardless of printer resolution. At its simplest, PPI stands for Pixels Per Inch, while DPI refers to Dots Per Inch. PPI measures the pixel density of an image file or how many pixels are contained in one square inch of the image. DPI measures the printing resolution of a printer or the number of dots of ink that can be printed in one square inch. But generally with photos/images you want a higher DPI for a higher quality output. Also, which one would consume less amount of toner? N/A The amount of toner is the same. To quote a response in the article I posted above: "A black 1x1" printed square uses the same amount of toner whether it's printed at 1200 or 600 dpi." DPI vs. PPI. DPI and PPI are often used interchangeably, but the two have a key difference. DPI, or dots per inch, refers to the number of printed dots within one inch of an image printed by a printer. On the other hand, PPI, or Pixels Per Inch, denotes the number of pixels within one inch of an image displayed on a digital screen. Use current calculator (page) to convert Image Resolution from Dots per inch to Dots per mm. Simply enter Image Resolution quantity and click ‘Convert’. Both Dots per inch and Dots per mm are Image Resolution measurement units. For conversion to different Image Resolution units, select required units from the dropdown list (combo), enter Z89s8e9.
