Dear Ducan, I just set up a Brother HL-5450DN Series on OpenBSD 6.6 amd64.
> 1. ulpt must be disabled: > # config -ef /bsd > ukc> disable ulpt > ukc> quit I studied tutorials on-line and previous discussions on @misc. I found out that for 6.6 amd64, if I disabled ulpt(4), I would not get the printer to work. On the contrary, I was able to get the printer to work by using ulpt(4). For other bits I followed previous tutorials and discussions, that I used footmatic-rip and so on. Yours sincerely, Xianwen
