I suspect that your customer's printers are so-called "driverless"
printers, and that they are advertising themselves via Apple's Bonjour
protocol, implemented in Linux by the avahi packages.
If so, you can see what avahi has found with:
avahi-browse -art
or avahi-discover.
If that is correct, I wouldn't worry about the duplicate entries for
the printers.
