I have a Epson CX8400 all-in-one printer.
Printing works fine.
Scanner works fine.
Card reader works fine.
However cannot monitor ink levels.
Sorry, not at my Linux box, so I don't have the links, but I do have an Espon inkjet (R220) and have used all the following successfully to check ink levels:
3) ink (command line)
Ubuntu 16.10 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
inkblot=sits in the panel and doesn't connect with the printer
mtink=reads levels but reports inaccurate quantiles, says the printer has 6 colors only have 4
ink=command line excites printer but no report
Libinklevel5=suppose to work with cups but can't find any report
any more suggestions? need all the help I can get
