what is /dev/??? for the parellel port ? escputil

[Dave Selby <dave_arahan@yahoo.co.uk>]

Hi, Ive started using escputil to check and clean my print heads, it works 
great but I also need to check the ink level, apparently I need to access the 
printer directly by defining the rew device, ie,

escputil --ink-level --raw-device /dev/???

My printer is an epson stylus C60, using the parellel port.
As a guess I tried par0

debian:/home/test# escputil --ink-level --raw-device /dev/par0

Cannot read from /dev/par0: Invalid argument
debian:/home/test#

Then par1,2,3 ... 
debian:/home/test# escputil --ink-level --raw-device /dev/par1

Cannot open /dev/par1 read/write: No such device or address
debian:/home/test#

Is /dev/par0 the parallel port for my printer ?
If so any ideas why escputil cant read from from to it ? I execute escputil 
from root ?
