Re: DPI and perception question

David,

 

    My conclusion is that the printer is printing at 240 dpi and not 300 dpi which is a 79.1 MB file

300 pixels per linear inch means 90,000 pixels per square inch.  A 20x24
print is 480 square inches, so the entire print is 43,200,000 pixels. 
In 24-bit color each pixel is 3 bytes.  So an uncompressed file for a
20x24 print at 300 pixels per inch would be about 129,600,000 bytes.
