Re: Escputil --raw-device and CUPS

I wonder if it could be as easy as telling escputil that you have a new model of epson printer (`new' means newer than Stylus Color 740 ...), i.e. add "--new" or "-u" to the command. I get a similar error as you do if I leave that out.

Oh, and sometimes it doesn't work the first time around, but you have to try like three times in a row or something. Don't know what's up with that. I've read what the problem is, but don't remember it right now.

I don't think CUPS has that much to do with anything escputil does. At least I've thought that it communicates directly with the printer, not through CUPS.

Everything available with CUPS admininstration seems to be working fine.
However, I want to check the ink level, and for this I need to use a command
line tool, escputil.

The output for

$ escuptil -i -r /dev/lp0  is
'Cannot parse output from printer'.

I've got the two-way option assigned in the kernel. Also quite liberal
permissions for access in the /etc/cups/cups.conf.

$ escputil -d -r /dev/lp0   gives an answer:

        @BDC ST

which I hope refers to STylus.

I suspect that there is something needed in the cups.conf file relating
to groups and possibly passwords, but I can't make head or tail of it.

Alternatively, I could get my wife's Windows Laptop to plug in to the
printer, install the Epson software, and check the ink-level there,
without any rigmarole. Defeatist though.

Is the access to the raw device deliberately difficult, or is this
something being worked on, or wished-for?
