If you start doing graphics, especially bit maps, you will find that
even the ethernet printers may not run at full speed, although for
bitmaps the communications time is so dominant that 9600 baud serial
lines prove painful. For higher level graphics the complexity of
the graphics determines the throughput, but imagen printers seem to
be able to do pretty well for realistic documents (imagen's release 2.2,
the first guaranteed to be able to print a page of arbitrary complexity,
seems to be about 10% slower when you invoke this guarantee than when
you don't).

Using the automatic page reversal is, to my mind, somewhat dangerous
in all environments except plain text using printer resident
fonts. Since the printer must accumulate all the pages before printing
any, it seems likely that you can fill printer memory with pending
impress commands and get in trouble when you need it for complex
pages. I have no experience of this, since we don't default to
page reversal on, but expect the host software to send pages in 
last page first order.
