No doubt there COULD be PC-NFS products out there which do not provide
printer redirection, but SUN's PC-NFS product works just like the
PC-I features you describe above. Up to three remote printers (i.e.
printers known to the UNIX lp spooler) can be mounted on the PC,
as LPT1 thru LPT3. PC-NFS will let you work with a 5 minute timeout,
or else you can configure and use a hotkey to tell the UNIX spooler
when printing is finished. Also, any DOS "exit" call will send the
job off, thus with a program like WP5.1, which intercepts any hotkey,
one can shell out to DOS and exit again, thus sending the job off.
Using a WP macro, one can even check first that printing is indeed 
finished (WP print queue empty) before executing the "exit".
