We have an application for which a PS printer is being used exclusively
to print two different files, repeatedly, but not in any predetermined
order, and with indeterminate time lags between jobs.  Both files are 
small ( < 8K ).  Our prime concern is generation time.  From a "cold" 
start, either file prints in 45 seconds.  After that, the second and
all subsequent files print in 15 seconds (ideal) if we send them one-
after-the-other with a time lag of no more than 5-10 seconds.  However,
waiting longer than 5-10 seconds triggers some kind of timeout, after
which execution time returns to 45 seconds (side note:  we are not baud
rate limited).  We've tried messing with the printer-specific timeouts
(it's an IBM E), but no luck.  Now, we're no postscript gurus; (as I'm
sure is obvious to the many of you smirking as you read this :) )
we need a way to retain whatever font/proc info allows the printer
to generate subsequent pages so quickly.  

Thanks in advance,

Andy
