Dave passed on the suggestion of brltty-trtxt -i en-nabcc -o en-nabcc which almost works. Here's an example of an original file:
135
Description: Binary data
And here's what the above command does to it:
flurgle
Description: Binary data
When I print this, anything without dot 8 works fine, but characters with dot 8 often print as a two character sequence. They also don't render correctly on my refreshable braille display using orca on linux while the original file is fine. Anyone have any further clues here? I'm quite curious to know what characters are actually being sent over the USB parallel adapter I'm using for the old printer but I've not wrung this info out of wireshark ... yet. thanks again for any help regards Peter -- Peter Rayner (he/him), Honorary Professorial Fellow, University of Melbourne mobile +61 402 752 379 zoom id 4431343191, join at <https://unimelb.zoom.us/j/4431343191?pwd=a1E5Z3JEOTRVQUJsaVdRbVUvR1QyZz09> mail-to: [email protected] google scholar: <https://scholar.google.com.au/citations?user=H3up71wAAAAJ&hl=en> I acknowledge the Traditional Custodians of the land on which I work, the Wurundjeri people of the Kulin nation, and pay my respect to their Elders, past and present I am sending this email when convenient for me, please only respond when convenient for you
