It is only carried by news.easysw.com, it isn't a Usenet group.

I've successfully talked to an old Canon BJC-800 and an Epson
Stylus Pro 10000 over Firewire using the SCSI backend.

There is only one command we issue, the group 0 print command,
along with the total number of bytes in the current buffer (8k in
the current implementation).

As I said before, the only place you can find SCSI errors is in
the kernel log, available via the dmesg command.
