I have a imagePROGRAF TA-20 connected to my wireless router. I'm running macos 10.15.1 and cannot get the Canon IJ Network tool to find the printer.
I have removed and re-downloaded the printer driver and the network tool. My firmware is up-to-date. I have connected via USB and Direct Connect in addition to WiFi and still cannot get the Network tool to recognize the printer.
I have another Canon printer (iX6800) that it picks up just fine.
