Started Presto service for my dad in the summer of '07; he loved it but about 6 months ago, the printer died. He lost phone service and called the local phone company for repair; a +$100 service call later, the service tech determined the printer was killing the phone line. I was not able to go see him until recently, and sure enough, as soon as I connect the printer to the phone line and plug in the AC adapter, the printer creates an "off the hook" condition on the phone line! Has anyone seen this before? On the back of the printer, I removed a small panel covering a USB jack; can the software be re-loded into the printer?
