Ink level KDE GUI fails: white space printer name issues?

[Andreas Mohr]

Hello,

on Dapper Flight 5/6, trying to fetch ink levels of my EPSON Stylus Color 860 via the graphical KDE Ubuntu system settings panel (system settings panel -> printer -> context menu on printer -> EPSON utility), I get the following error:
"Cannot open /Stylus Color 860 read/write: No such file or directory"
The printer device URI is said to be "usb://EPSON/Stylus%20Color%20860", thus I strongly assume that it's a whitespace escaping issue.
Note that other items in this GUI panel (print head cleaning, ...) do work properly.

It may be rather likely that this bug is not about escputil, but instead about the GUI panel. Please update the package name of this bug if this is the case.

escputil 4.3.99+cvs20051122.dfsg.1-2ubuntu1

Thanks!

please could you recheck after a dist-upgrade to dapper 20060414, removal and reinstallation of the printer?

In my case to work around the problem I "chmod 666 /dev/usblp0". Then change the printer interface properties to use URI: "usb:/dev/usblp0". The Ink Level check then works. Then if I check the "Use direct connection" button I can run the rest of the tests.

Help on escputil suggests it requires a raw device to work.

    -i|--ink-level Obtain the ink level from the printer. This requires read/write access to the raw printer device.

escputil 5.0.0~rc2-0ubuntu3

Same problem here on Dapper Flight, after a dist-upgrade on 2006-05-05, i.e. I get the following error message when I try to check ink level with the escputil utility:

Error
Cannot open /Stylus CX5400 read/write: No such file or directory

This utility used to work flawlessly with my printer on my previous Debian Sid installation.

I've tested it again, now with the official Dapper release, and it is still not working, i.e. with the same error message:

Error
Cannot open /Stylus CX5400 read/write: No such file or directory

Please attach your /etc/cups/printers.conf.

[mlaverdiere (mlaverdiere)]

There is someting strange: if I try to copy the file /etc/cups/printer.conf,
I get the following error message: can't read the
file /etc/cups/printer.conf (my translation, from French)

I've tried it as a root and as a normal user. I've even tried to stop cupsys
dameon in case it was locking up the file. It didn't make the
file "accessible".

So basically, I can't provide you with a copy of my printer.conf file....

Any idea of what's going on?

[Ante Karamatić (ivoks)]

Do it like this:

sudo cp /etc/cups/printers.conf /tmp/
chmod 644 /tmp/printers.conf

then attach /tmp/printers.conf

Thanks for the tip. It worked.

Here's the requested file.

Stop cups (sudo /etc/init.d/cupsys stop), change DeviceURI to:

DeviceURI file:///dev/usblp0

and start CUPS (sudo /etc/init.d/cupsys start). This is temporery solution. It should work...

[Till Kamppeter (till-kamppeter)]

Note: This does not work under Edgy, as CUPS 1.2.x only supports USB URIs of usb://EPSON/Stylus%20CX5400 type and not of usb:/dev/usblp0 type any more.

[mlaverdiere (mlaverdiere)]

Sorry for not responding, but I didn't and won't have access to the Epson printer I have at home for several months, since I'm living in an other country for a while. I'll be back at home in December and will then be able to give the requested feedback... if it can wait...

[mlaverdiere (mlaverdiere)]

This utility is still not working for me under Edgy. The error message is still:

Cannot open /Stylus CX5400 read/write: No such file or directory

I'm ready to do some testing following what was suggested above, but I don't know what is the appropriate step considering the comment on the way Edgy handle device url. What should I do?
