Have you tried plugging it into a phone line that isn't this one? Like one typically used for a phone, just to eliminate the possibility of it being the line in some way? Should not be too hard to do since it is a relatively movable printer and it would only take 30 minutes to see if it works.
Unfortunately updating the firmware to the one you linked, did not make a difference.
Also i do not hear anything poling the printer at the time it wakes up.
Thank you for all your help Joe!
The one I linked is the latest one. 68.12 is just the beginning of a few releases.
Those are the versions so far.
If you ever want to know between versions which is the newer.
Then you will likely need to hook up a handset to the line and see what is happening on the phone line, either something is polling the printer, or the printer is initiating something, and you will never guess.
You could try simply updating the firmware on the printer, but it isn't likely to fix this.
