Ok, I had to move my printer out of my office at school and it is now home. However, I'm having lots of problems communicating with it over wifi now. I had a spare RPi 3B+, so I installed it and it won't work at all. It will not run the display on the printer or anything. All I see when I turn it on is a red blinking light; never green. So my question is, do I need to modify the configuration.h file on the SD card and re-flash the firmware in order to get it to work? Or, will it never work on a 3B+? I would really like to use the B+ because it's dual band wireless and I can pick up a different network, and possibly get a stronger signal. Any help would be appreciated. The B+ I have is brand new, never been used before. Thanks, P. Wayne EDIT: Sorry, I get confused. I guess the firmware really has nothing to do with this. Maybe I need an updated boot image?
