Printer trouble

[barknech@ph-cip.uni-koeln.de]

I am trying to set up a NEC Silentwriter S60P-Printer for use under Debian 1.2. 
It is a Postscript-Printer, but I don't have any documentation. (Found the device in a 
factory's trash...)
It works great with Win95, but I am not able to print anything with Linux. 'lpr' does nothing, 
and I cannot cat a file to /dev/lp1 (as root, of course). I do not use plip, so there can't 
be any clashes at the parallel port?

I fiddled around with tunelp, but it keeps saying things like:

#	bash# tunelp /dev/lp1
#	/dev/lp1 using polling
#	bash# tunelp /dev/lp1 -s
#	/dev/lp1 status is 223, on-line
#	bash# tunelp /dev/lp1 -i 11
#	/dev/lp1 using IRQ 11
#	bash# tunelp /dev/lp1 -s   
#	/dev/lp1 status is 223, on-line

with no positive effect on printing.
I compiled lp-support as a module in the kernel, kerneld starts it at boot time.

#	bash# dmesg | grep lp
#	lp1 at 0x0378, (polling)

Somehow the printer seems to receive data, when I try to print, because its
display says 'PROCESSING` , but then it becomes `READY` again.
Anyhow: No output in tray.

Can someone help me? Are there any tools to debug my problem further than with tunelp?
Like a kind of 'ping' for lp-devices?

Thank you in advance
