Getting Fedora 32 duplicate HP network printer & scanner

[boricua (Francisco)]

Hi. I have a HP Laserjet Pro network m428f printer/scanner. I can both sprint and scan from my network using the HP graphical tools to locate/configure the machine. My issue is that I am getting two m428f installed, both for printer and scanner, from my Fedora settings. I guess I need to remove the native fedora printing tool to avoid duplication, but don’t know how to proceed.

Check out the current CUPS settings:

ls -l -R /etc/cups
cat /etc/cups/printers.conf

sudo lpstat -s

What does this say?

Here’s the output:
[francisco@main ~]$ sudo lpstat -s
no system default destination
device for HP_LaserJet_Pro_M428f-M429f: hp:/net/HP_LaserJet_Pro_M428f-M429f?ip=192.168.88.202

Well, I’m not sure where the duplicate comes from, since only one printer is configured in CUPS.

I am including a couple of screenshots. The first shows one HP printer in settings but two HP scanners in Simple-Scan. The second screenshot shows two HP printers in settings after launching HP’s graphical tool. Simple-Scan keeps showing two HP scanners. Hopes this helps.
