Running "lpstat -s" shows "implicitclass" in RHEL 7.7

Solution Verified - Updated -


After setting up a master print server as described in How do I set up a master print server using CUPS in RHEL? Running the command "lpstat -s" on a CUPS client print server shows implicitclass instead of the output shown on the master print server. For example, on the CUPS client system:

# lpstat -s | grep 'device for' | head -n1
device for wms: implicitclass:wms
device for wl5: implicitclass:wl5

but on the CUPS master print server:

# lpstat -s | grep 'device for' | head -n1
device for wms: lpd://print1/wms
device for wl5: socket://
