Will Repetier-Host 2.3.1 run on Linux Mint 21.1

wa3scm

I have Linux Mint 21.1 running on a Dell 64 bit laptop. When using the standard repositories to install Repetier-Host with Synaptic Package Manager a very old version of Repetier-Host is the only version. available.
Having downloaded the appimage of 2.3.1 enables me to "run" Repetier-Host. I can load and slice a .stl file. However I can not connect to the printer.
When configuring the printer settings the choices are Serial Connection, TCP/IP Connection, Virtual Printer, and Repeteir-Server. I think I should use Serial Connection because my printer is connected via USB. Is that correct? Would I be better off also installing the Repeteir-Server?
Having selected Serial connection and moving to the Port selection my choices are Auto, /dev/ttyprintk, and /dev/tty. Which of these devices should I choose.
Finally what Baud Rate and Transfer Protocol should I be using. Is the baud rate something I should be investigating in the 3d printer itself?
Thank you for your help.

Repetier-Server is the best choice since it runs independently in the background, so you can close host and print will continue. Also server is better with communication. Otherwise serial is the choice. In server these would start with /dev/serial/... which is a link to /dev/tty....

To find out the correct name for host run in terminal
ls -l /dev/serial/by-id
and see to which of the tty files it points. If there is only one printer that is the one you want.
Protocol automatic is ok, baud rate depends on printer. 115200 or 250000 are the most common used baud rates.

No serial ports showed up using "ls -l /dev/serial/by-id"
Did some research and found this command for live messages "dmesg -wH" which resulted in a full blown device listing followed by time stamped activity messages.
To generate the attached screen I simply plugged the printer's usb cable into the laptop usb port to generate the first block then pulled the printer's usb cable out of the laptop usb port. Plugging in and pulling out a second time then generated the second block.

You have BRLTTY installed, uninstall it unless you need a braile reader. It connects to every serial device when it shows up and is known to cause issues.

Not sure if this is all, check
sudo lsmod

if the ch341 driver module loaded as well, but looks like it is known.

Removed BRLTTY then Repetier-Host began connecting to the "tornado" type 3 d printer. It took a bit off fiddling to get actual communications setup correctly. The key to me was Repetier-Host started offering me a USB port in the printer settings.

Thank you for such quick correct advice!
