My first instinct is to suspect IC25, the 1488, receiving noise from the 8302. That's where I'd start looking. I have a logic analyzer and that's the first place I'd look. Either the 1488 is noisy for some reason, or it is cleanly converting an input from the 8302.
I will send a photo.
The characters are not letters but all simbols that it doesn't exist on the QL character set.
Thanks for check.
