[cups] Cannot disable low ink warning

[Michael Sweet]

Well, this message is coming from the printer, probably either via SNMP or IPP.

You can disable SNMP and IPP supply level checking by adding the following lines to your printer's PPD file:

    *cupsIPPSupplies: False
    *cupsSNMPSupplies: False

This can be done using the lpadmin command:

    lpadmin -p printer -o cupsIPPSupplies=false -o cupsSNMPSupplies=false -o printer-state-reasons=none

I am only getting this warning since a few days ago, and as far as I know, nothing has been changed on the printer. Printing is fine, by the way, it's only the annoying warning.
