How about reading the support files in the cdrecord source:
README.parallel:
This file is intended to help with ATAPI <-> Parallel Port devices on Linux
Before you start, read
http://www.torque.net/parport/paride.html
Make sure that your parallel port device is set up to EPP mode
from within the BIOS. In many cases it is best to set the PP delay to 0.
Here is a short explanation how to make the FreeCom Traveller work
in 4x speed on a notebok:
1.) Set BIOS for parallel port to 'EPP'.
2.) Load drivers in default mode:
# modprobe paride
# modprobe <driver for parallel port adaptor>
# modprobe pg
in case of a FreeCom Traveller this is:
# modprobe paride
# modprobe friq
# modprobe pg
3.) Check kernel log for paride messages:
# dmesg
...
paride: version 1.04 installed
paride: friq registered as protocol 0
...
parport0: PC-style at 0x378 [SPP,PS2,EPP]
parport0: no IEEE-1284 device present.
...
pg: pg version 1.02, major 97
pg0: Sharing parport0 at 0x378
pg0: friq 1.01, Freecom IQ ASIC-2 adapter at 0x378, mode 4 (EPP-32), delay 1
pg0: CD-R/RW RW8040A, master
...
4.) load module again but use different parameters:
'drive0=IO-Port,Protocol,Unit,Mode,Master/Slave,Delay drive1=...'
if you have only one drive at the parallel port
'drive0=IO-Port,0,0,-1,-1,Delay' e.g. for Delay = 0:
# modprobe -r pg
# modprobe pg drive0=0x378,0,0,-1,-1,0
5.) Check for optimum delay using for maximum speed using cdrecord -dummy
6.) Use the file rc.pp and modify for your needs
