If anyone still has this problem I found the solution in Ubuntu forums (but unfortunately didn't take their name- post appeared during 2006 I think). The problem is that /dev/usb/lp0 does not have rw permission for logged-on user.
The solution starts by editing /etc/udev/rules.d/permissions.rules. Under # Printers and Parallel devices, one line must be changed: BUS=="usb", KERNEL=="lp[0-9]", GROUP="lp" becomes BUS=="usb", KERNEL=="lp[0-9]", GROUP="lp", MODE="0666" It is possible you also need to create the lp group (I did) and put yourself into the lp group. After this the device is accessible permanently. Hope this helps someone - and gets the solution into the next release.
