My 4 in 1 HP printer has broken. I have a relatively good laser printer, but need something similar to use as a fax, scanner etc.
Unfortunately, only the dpi's are displayed and not the ppi.
Where would i find it?
The ones that I am interested in are Canon MX410; Lexmark Pro 205, HP J4 500 or HP 6500A.
Can anyone help?

There won't be any reference to PPI in the specifications because it's a property of an image, which sets the relationship between the content of the image and the size that content represents in the real world, such as a printout of the image.

Use the DPI figures for comparison between the physical devices of scanner and printer.
