The Imagewriter II can dump something like 350 bytes (of 9-pin data) per second (time a screen print 512*345/8 bytes). Now, if you read the 24-pin BYTE benchmarks from 2 months ago, you find that very few printers can approach this output speed. The one exception is the Okidata Microline 393, which can dump 2400 bytes (of 24-pin data) per second. This works out to slightly more square-inches per second of printing. Most other 24-pin printers run at 1/3 to 1/2 of the Okidata's speed. So most 24-pin pinters are 1/3 to 1/2 as slow as the Imagewriter II, for printing graphics bitmaps. Draft mode is better, of course. Don Gillies, Dept. of Computer Science, University of Illinois 1304 W.
