Yes, you are right.

So, the problem seems to be something with the communication at the 
backend level.  If I run this command to send some pcl to the printer:

( exec -a 'scsi:/dev/sg1' /usr/lib/cups/backend/scsi oceps372a-16 root 
abc 1 "" /var/spool/cups/d00016-001)

I get this error:
WARNING: SCSI command timed out (2); retrying...
WARNING: SCSI command timed out (2); retrying...
WARNING: SCSI command timed out (2); retrying...
WARNING: SCSI command timed out (2); retrying...

And if I send it to my old cd-rom I get the same error (same 
scsi_req.status).

[1]says the device is not ready.

What else can I do to check why it isn't ready?
