My printer can output at 1440 and 2880 ppi. Some people advocate using a photo resolution of 360dpi (as it is exactly divisible into printer resolution) others say print at 300dpi. Adobe elements defaults to 240dpi.
What is the consensus of opinion on this- which gives best VISIBLE photo quality ?
A can of worms, I think...
 
DPI refers to how many physical dots of ink your printer can lay down, however it takes multiple dots of different coloured inks to create the effect of a single colour pixel as found in a digital image. This number varies between manufacturer but and is referred to as a printers native resolution. It's generally considered good practice therefore to send an image to print at your printers native resolution or a multiple thereof (to allow easy interpolation) in order to get the best image quality. For a canon this tends to be 300ppi, I'm sure others can advise for different manufacturers.

Hope that makes sense.
 
Honestly it doesn't matter a jot! The difference between 240ppi and 360ppi will not even be noticable. I have the Epson R2400 and have tried numerous settings. Never noticed a difference!

Resolution also depends on the size of the image you are printing - Larger prints don't need a high ppi count.

Andy, what I do note is that you are confusing dpi and ppi.

dpi is the PRINTER resolution - so 2880 x 1440dpi.

Images are made of pixels and are output in pixels per inch - be it 240ppi or 300ppi or whatever.
 
If you want the best possible quality then set to 360 or 720 if you have the pixels and set printer to highest resolution. Looking at a print on a wall at normal viewing distance you'd be hard pushed to notice a 180 V 360 print. Setting it to anything in between wont make any perceivable difference either. Setting the quality on the printer wither 720, 1440 or 2880 will make a difference.
 
Thanks for the most informative of replies .It's certainly "food for thought"

If you simply want to print family snapshots or craft projects, a 600 x 2400 dpi
scanner will most likely be sufficient for your needs. However, if you want to do more creative
projects, higher resolution will give you greater creative control and more enlargement options. For
example, with a 1200 x 2400 dpi scanner and a transparency adapter, you can take a 35mm negative
and create a Photo Quality 3" x 5" print on your ink jet printer

The OP didn't mention anything about scanning? And your figures are based on 300ppi being acceptable quality when in fact as noted above you could easily send the image at a lower ppi and get an excellent and larger print.
