i have been having a problem getting my new HP 82160A HP-IL module to transmit to either an old 2225B HP-IL printer or 82973A PC interface card. the card and printer seem to work fine together, but the HP 41CV with module can only produce a "Transmit Err" when uploading programs, data, or printing.
the function list CAT 2 displays the module programs, so i'm guessing this is a wire problem. is there a way to confirm this?
