The difference is that the scan is held as an image, with a size relative to the scanners 'page; setting and when you print that image the page setting of the printer is also used - so if you scan on an A4 scanner, and Print on an A4 printer the print should be almost the same size as the scanned item.
If you use a slide scanner, that process is usually set to scan the image at a high resolution, and then print the image at a lower, and consequently larger (more spread-out) resolution as in scan a 1" image at 1200 dpi and you have 1200 dots to print in each direction - print that at 300 dpi, and you need 4" for 1200 dots Now - the screen Say, for example the software takes the image - say 1" square @1200 dpi and shows it on a screen with a physical resolution of 1280 x 1024 (using the same resolution in the video board mode specification to windows That would take 1200 x 1200 screen pixels to show the entire detail recorded by the scanner, so you would need to pan the image vertically to see all of it (a combination of the top and/or bottom 176 rows would not be visible) The software can probably be set to show the view at varying magnification - and may even do that automatically to fit the screen, or the application window - (See irfanview) When you tell the software to print the image you can probably tell it to modify the size of the image to fit the entire page, be the same size as the scanned image, or any other sizes within the printers capability If you have a very high dot-pitch printer you can really annoy people - get MSword to print a hundred or so logical pages on a single sheet of paper - consider that most characters are decipherable when printed using a matrix of 7 x 9 dots - so a 1200 dpi printer should (in theory) be able to print readable text at 120 lines per inch, but practically I'd limit it to using a 14 x 18 matrix - however that's still a 60 line page in a inch of paper - 11" paper so that's 132 logical pages on the sheet of paper Then again - take an image of the page (scan it at 32 bit colour and save as a .bmp) and replace the text within word with an image of the page (An annoyance used by MS in the Win95 documentation) Then wait 30 minutes for word to load the 1 page document JimB ----- Original Message ----- From: "K.

What print setting do I need to tweak?
