Electromagnetic gray scale printer |
摘要 |
A gray scale image poster printer reproduces a digitally stored bit map image on a printer using an electrostatic and magnetic toner to generate gray scale images by expanding each line of the original stored image into a plurality of subpixels along the horizontal scanning lines and by synchronizing the printing of the subpixel lines with a changing magnetic field that changes the amount of toner deposited in each subpixel.
