    Agree 100%, and mainly because I too come from a commercial print background and understand your figures. (Offset - web and sheetfed)

    However inkjet printer manufacturers also like to muddy the waters. My Epson 3880 manual p133 states: Maximum resolution 2880 x 1440 DPI. This is also mentioned in more than one place in the manual.

    As far as I can ascertain my Epson driver has a maximum resolution of 720ppi thus leading to the Logical (I hope) conclusion, that the printer prints multiple dots to complete one pixel.

    And to thinks we started with a simple original post about final image size!

    Yes, you are right, the driver needs to render the color of an individual dot, with CMYK subpixels with varying
    droplet sizes. The dot resolution of Epson printers is typically 360 or 720 dpi, or 600 dpi with the newer P400/600/800 models, the CMYK subpixels in each dot are printed with a max of 2880x1440 or 5760x2880 etc. You cannot address these subpixels via the driver individually. The size of the spoolfile would get into the Gigabytes quickly. The same applies to Canon printers, their dot resolution is 600 dpi, but the rendering uses a pattern up to 9600x4800 - you directly could print microfilm with that resolution....

    @stratman It looks like we are now having two parallel discuassions.

    "My old" Win 10 has the same three photo apps as the Anniversary version has. My right-clicking a photo and choosing "Print" opens the same window as if I open the photo in Windows Photo wiever and selects print. I just thought my suggestion was the easiest way.

    Canon Easy Print EX is also OK, as are a lot of other programs/apps. Just remember to uncheck "Vivid Photo" in Canon Easy Print EX else the colours will be exaggerated.

    It is said the best program is one that you are familiar with and which does what you need. I think right-clicking a photo and choosing print is the easiest way to print photos. Others might have other opinions.

    @Roy Sletcher, This Pic is made up to be 9 PPI but your printer will not just use one colour in the same space, it can use dozens of colour so it can get rather crowded in just 1 inch of paper when printed at the 360 or 720 PPI..

    Partially yes if you mean concerning the OP. No if you meant the two of us. My post addressed both your post and the OP's original post.

    I meant to say the following in my last post but forgot -- I wonder if the OP used Windows "Photos" to view and print images. If so, then maybe that was the issue.

    That's a good example of the potential confusion over terminology. Your image may represent 9 pixels in a square inch, AKA 3x3 resolution, but the inkjet printer uses a DPI (unfortunately called "PPI" in your example) of 300 or 720 (in your example as well) when printing the actual image. In other words, the printer will use up to 300 or 720 dots of ink per inch to represent those 9 pixels per inch of the digital image!

    The printer's DPI is essentially independent of the digital image's PPI. Similar terms representing similar things but should not be used interchangeably. Unfortunately they are.

    Unfortunately, it’s the printers’ terminology that wrong (Forked tongue) it only represents DPI it doesn’t actually use it..

    i understand and i had used for long time windows photo viewer and canon easy print, but what happens if u want to print in a format that is not available like 12 x 12 ???? cause the layout that brings are contact sheet. wallet, 3.5x 5, 8 x 10, 5 x 7,
    4 x 6 and full range that could be if windows appears paper size of 12 X 12 but it's doesn't have those numbers.
