im not sure how to fix this yet but I think it may have been caused by unplugging the print head from the rest of the machine. Im now looking for the manual to see if anything is in there. please repost if you have anything on how to fix this
error code pp000, I think stands for printer jam. you have to clear the jam and then unplug the register for a few seconds. my print head was obstructed from sliding over when the register first started up, cauisng this error. once I found the problem I rebooted and it works great
