Printing Colours

[anonprivate]

I would strongly disagree with that. There's lots of packages still using GTK2:

$ apt-cache rdepends libgtk2.0-0 | wc -l
1142

Sure GTK2 is old, but it's not compatible with GTK3, lots of rewriting required, and the libraries will be available and installed in Ubuntu for a long time, many years I hope.

My perspective...
GTK3 met severe resistance with non-gnomish developers, owing to its developers' arrogant gnomish-ness. Many projects have switched to Qt, and others have only recently moved to GTK3, like firefox. One project, Audacious audio player, has even reverted back to GTK2 after porting to GTK3.

Sorry OP, the above discussion doesn't help you. I suggest installing python-glade2, with muon, or:

sudo apt install python-glade2

I can import gtk.glade in python 2.7 after installing that. Does escputil --ink-level work?

I downloaded the python programme and am making some progress.

I typed stylus-toolbox in konsole and the ink level diagrams appeared. However, they are set to zero. This is wrong, I can print. I was pleased to see that my printer is listed in the supported printers list; however, I don't think that the changes are being saved in .stylus-toolbox.conf because the command prompt did not return when I saved the preference (note, it look like .stylus-toolbox..., may be a small comma!).

Couple of other points. I can't find stylus-toolbox in the menu system. Do you know where it might be located. There should be an icon in the tray, this is also missing.

Overall, progress being made.

Best wishes.

Ps. I have just looked at .stylus-toolbox.conf in my home directory. It looks like SX100 (my printer) is saved

I have more success when running stylus-toolbox, although the ink levels are not being recorded.

I may need to locate the Device Port.

The only information that I can glean from the CUPS interface is:
usb://EPSON/Stylus%20SX100?serial=KQEZ387420&interface=1

This is not a hard disk path. I have never been able to locate this path - from the hard dive to the printer

The page you referred to is not for the SX100. In addition, the link at the page takes me to a page written in Japanese.

Any idea which Glade package I should download to ensure that Stylus Toolbox functions.

Sorry, I use Canon printers & with Canon numbering that would be the same series/driver (I use mg7100 driver for my 7120) Anyway, does the cmdline (non GUI) work? I linked to another GUI also

You're cmdline should be along the lines of

sudo escputil -d -r /dev/usblp0
sudo escputil -i -r /dev/usblp0

...

If you have mlocate installed you can issue
sudo updatedb
and then
locate stylus-toolbox

Or,
whereis stylus-toolbox

From the above

'When i type escputil --ink-level

When I type:

andrew@andrew-Dell-DM061:~$ stylus-toolbox --ink-level

I see the ink levels graphics box, but all levels are still set at zero, which is incorrect.

How do I check, and, if necessary, change the read/write access to the printer device?

GreyGeek:

I know where stylus-toolbox is located within the file system, but, I do not know why I cannot find the link in the menu system; or, the icon in the system tray! (lower panel)

[GreyGeek]

Ah, some apps, especially the older ones or ones created for different distros, do not create links in the menu or system tray because the methods they use are outmoded. In that case you can use "whereis" to find the executable and then create a menu entry yourself Recently, I found that "simplenotes" failed to create a menu entry and I had to do it myself. Newer apps usually do not have problems creating menu or system tray entries.

Thank you

Do you know how I can locate the hard disk path to my printer. The path given by cups is not a proper path that is recognised by Stylus Toolbox.
I believe that it is located somewhere within /dev/bus/usb/001/

[jpenguin]

I think you can see the bus number with 'lsusb'

Here is how, but unless you are a Linux socket developer I doubt you have the ability to make any changes in /dev that would be beneficial to your system. Quick quiz: do you know what "magic numbers" are and what they mean, and what does the 'c' in the permissions stand for? (without having to DuckDuckGo them)?
