Stange Cups Problem: "/dev/lp0": Permission denied

Hello,

I got a problem with cups.
Today I was once able to print with cups to my epson stylus color 1520.
I don't know why, but after the installation of turboprint (That might 
not be the reason) cups reöports, t5hat it's not able to open lp0:
[Job 8] Unable to open parallel port device file "/dev/lp0": Permission 
denied

I'm using hoary amd64. 

I don't have any problem to print from winXP x64_x86.
$ dmesg|grep parp
parport: PnPBIOS parport detected.
parport0: PC-style at 0x378 (0x778), irq 7, dma 1 
[PCSPP,TRISTATE,COMPAT,ECP,DMA]
parport0: Printer, EPSON Stylus COLOR 1520
lp0: using parport0 (interrupt-driven).

The dma setting 1 or 3 doesn't affect this behaviour.

lpq: Stylus-Color-1520 is not ready

When I print directly to the device with cat the printer starts 
blinking, but nothing prints out.

$ uname -r
2.6.11.8.20050506

$ grep PARP /boot/config-`uname -r`
CONFIG_PARPORT=m
CONFIG_PARPORT_PC=m
CONFIG_PARPORT_PC_CML1=m
CONFIG_PARPORT_SERIAL=m
CONFIG_PARPORT_PC_FIFO=y
# CONFIG_PARPORT_PC_SUPERIO is not set
CONFIG_PARPORT_PC_PCMCIA=m
# CONFIG_PARPORT_OTHER is not set
CONFIG_PARPORT_1284=y
CONFIG_PARIDE_PARPORT=m
CONFIG_I2C_PARPORT=m
CONFIG_I2C_PARPORT_LIGHT=m

foomatic is set to gs-apfl.

In the BIOS the paraport is set to ECP/ECC DMA1.

I don't have any clue. help is highly appreciate.

Kind regards

Gerhard Gaußling
