I posted a similar message a few days ago, but it seems to have vanished, so 
here goes again : 

I'm evaluating 24 pin dot matrix printers for printing graphics images. 
I have a couple of questions about quality and speed.

The ads I've seen for 24 pin printers claim 260 dots per inch. Is this 
realistic, or exaggerated ? What is the (subjective) quality of such an
image ? Is it actually better than a laser printer in 200 dpi mode ?
How much worse is it from a laser printer in 300 dpi mode ? 

Published speed specs are usually 
quoted as 50-something characters per second, near-letter-quality mode. 
How does one convert this into graphics printing speed ? For printing
graphics, what is the speed limiting factor : the speed of the parallel
or serial port from computer to printer, or the print engine itself ?

Thanks a lot  for any information ,
