[TUHS] Re: Typesetting ROFF/NROFF Documents

Looking at https://github.com/TheBrokenPipe/Teletype-37-PDF/blob/main/.images/test.png My recall is that the TTY33 I used had "vertical stops" set to every 6 lines (like the HT calculation but with a different constant), so VT was equal to between 1 and 5 LF's. In my mind I can hear, "feed feed feed (small delay) feed feed feed feed feed" (that is, the first VT could be fewer lines), but I might be thinking of VT followed by FF. So it's also possible it was always 5/6 LF's, my memory is from almost 50 years ago, the TTY37 could have been different, or the particular TTY37's in use on early UNIX systems could have been set up differently! Back in the day, line printers had carriage control punched tape loops which allowed different format effectors in column 1 of the output to have different stops, 1 was FF, it never occurred to me that HT on a TTY with green/white striped paper could have advanced two (three line) stripes (or that TTY vertical spacing was remotely accurate enough to have it work!) Are there any font files with the needed characters (with or without imperfections) and realistic character shapes?
