Well, working
backwards from DPI and print speed gives about 3MHz dot
clock:
300DPI * 11 inches (paper height) * 3ppm = 9900 lines per minute
(thus, the line rate is 9900Hz, or 9.9kHz)
9900lpm * 300 dots per line = 2.97e6
(thus, the pixel rate is 2.97MHz)
Am I missing something, or is that too low by a factor of about 8 or 9
(the number of inches along a line)? It's somewhere in the region of
24MHz, surely.
