Since there isn't an infinite number of combinations screen sizes, printer
settings and OS', one would assume there would be software that would
make this possible.
Um, you can calculate the size that an image will print out based on the
number of pixels in the image vs the resolution of the printer. It has
nothing to do with monitor resolution. And printer resolutions can be
adjusted by the user.
An image 300 pixels wide will print out 1" wide on a 300dpi printer. If
you want that image to print out 5" wide on a 300dpi printer, then you
have to resize the image by 5 times or 1500 pixels -- which is
uncomfortably wide on the average monitor. If you have an image 100
pixels wide, then it will be 1/3" when printed out on that same printer.
Of course, it may just me me, but my Deskjet prints out webpages at
96dpi, not 300dpi. That 300 pixel wide image will print out at just
over 3" wide. The 100 pixel image will print out at just over 1". So,
the lower the dpi of the printer, the larger an image will print out on
a dot for pixel basis.
If you want to offer people images to print, make your images in various
resolutions (Coarse(96dpi), Medium(150dpi), Fine(300dpi) and, if you
dare, Photo(1200+dpi)) and then create links to the images for download
in the format of your choice rather than attempting to plug a
one-size-should-fit-all, non-web-friendly format image into a webpage.
