Printers are displayed in Control Panel\Hardware and Sound\Devices and Printers often with a vendor supplied icon.
Is it possible to replace that with a custom icon?
In Windows Explorer, go to:
And open the appropriate language-specific folder (e.g. for US it is
en-us). There you will see subfolders corresponding to your installed devices. In each subfolder you'll see a folder named DeviceInformation. In that folder is the icon for your device.
You can either replace the icon itself, or you can edit the
DeviceInfo.xml file and specify a different icon to use.
