Apologies if people already saw this, I didn't see a copy so suspect it went astray. ---------------------------------------------------------------------- Hmm, I'm getting back to this after only a year's break ... To recap I have output which mixes ascii and unicode braille patterns and I need to print these on an ancient printer (a Braille Blazer from 1998) which seems to understand North American Braille Computer Code (nabcc). It's an 8-dot printer and the notation I'm using has a lot of dot 8 (i.e high bit set). The translation seems to work, i.e checking the dot patterns that correspond to the 8-bit characters *after* translation seem to match the original. I can't, however, print them. This is over a USB-parallel adapter. Things with dot 8 present don't seem to be printing correctly. A capital b (dots 1 2 7) will appear before each such character and frequently the printed character will be offset by 0x80 from the desired, as iff the high bit was being ignored. I suspect this is either a printer or Linux device driver problem but in case anyone has either a brltty explanation or workaround I thought I'd try here. Any pointers very much appreciated. regards Peter
