Is there any incompatibility between the integrated Ap 20x and the Ap one AX?

I have observed that the devices connected to the integrated AP of the B20X do not communicate well with others located behind AP One AX Lite. The printer (in network) does not work if I put it with the ssid of the 20x, but if I put it in the ssid of the AP one Ax, it works without problem. Is there any incompatibility between the integrated Ap 20x and the Ap one AX?
Thank you.
