I have a question, I copied the program into Raspberry Pi pico when I was working on the project of thermal printer parking system, after that I tried to copy other programs but they failed, is it because the pico board can only copy one program?

Did you press "Boot" button?

I think you'll need to stop the currently running program on Thonny. Try clicking the red stop button at the top. The program should stop and you should be able to upload new program to the Pico.

If it still doesn't work, you can always reset the Pico by uploading flash nuke .uf2 file. More info here https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/circuitpython#flash-resetting-uf2-3083182-8
