- This isn't too diffucult of a problem if you understand math. A sheet
- of paper is 8.5"x 11". The laserjet 4 does 600 dots per inch (DPI).
-
- 8.5 * 11 * 600 * 600 = 33.66 M bits / 8 bits per byte = 4.2075 MB

- Did you get the error message from DOS or some application trying to
- generate the image OR was the error message from the printer?
