Yes, there is. /dev/lp0 is the first parallel port printer. I'm not
sure why /dev/par0 but on my system seems to be the same as /dev/lp0.
/dev/parport0 is a new device (new in Linux 2.4) which represents the
first parallel port (or a device attached to it).

Major 99. The minor number specifies which port: 0 for the first, 1
for the second, etc.

VMware ships a very old version of a driver for /dev/parport0, called
(vm)ppuser. Perhaps you need to compile/install that.
[The new driver is called ppdev, and unfortunately has a different
interface but the same major. :-( Perhaps one of the guys at VMware
would like to take the ppdev 2.2.x backport I made and add their
PPGETBASE hacks to that, to prevent this incompatibility getting
worse: any VMware guys on this list?]
