I've been using the nano for a couple of months and the disk and memory functionality has been great. I was having some issues using TIprint and thought it was an issue with my old PC. I purchased an Apple Imagewriter ii off eBay to see if a real printer still had the issue (it does). When I am sending output to the printer, there are what appear to be random characters being printed at the beginning of the line. It's really not a big issue until a control character shows up randomly. I know the com parameters are set correctly between the port and the device. Any other nano peb users having this issue.
