Good point Lloyd -- and how I'll likely proceed. Backpack is very cool and a great interim solution.
Would be neat if there was such a thing as an RS-232 -> WiFi printer spooler that just sat on the RS-232 and sent print jobs to the local wifi printer. I did a quick search and couldn't see anything of the sort available, and I'm sure developing it would not be that easy, even using microcontrollers like the ESP8266 etc. --Brad On Fri, Aug 27, 2021 at 9:27 PM Lloyd Johnson <lloydel...@comcast.net> wrote: > Brad, > > > > Thanks.
