I'm having a difficult time getting my printer use a proper print density.

Perplexingly, it doesn't have any print quality settings apart from Toner Save.

With toner save enabled, the print comes out too light. However, if I disable it, the print is too dark - literally as dark as it can be.

  • I have tried every setting. It seems to ignore most of them. (like gamma, saturation and brightness). It only responds to the Toner Save setting.

  • The printer connected via network (wifi), with a driver used from Canon's website.

  • In Windows everything is OK, and I can adjust the density to a desirable amount.

Isn't there some way that I can print with a density somewhere in the middle? Could this be a driver problem?

EDIT: I just noticed that when i try to print from Chrome in the preview, i see a color document instead of a greyscale. This is not a color printer. With my previous printer the preview was gray.

2n EDIT (10/10/2017): I tried to recalibrate the cups printer with: cups-calibrate but i haven't managed the desired print.

3rd Edit (12/10/2017): I have tried everything! I even did a manual edit of the etc/cups/ppd file. I manually added to that file all the driver's command line options from Canon's Site ! Even though i knew all options wasn't for my printer i played with them with no success. The most interesting option i added is CNTonerDensity. Still with no success.

Every time i get the same dark print like the example 3.

I have tried to get the brightness up with Gimp and managed well results. So i believe it's a brightness setting.

Just added a bounty.

4th Edit: (24/10/2017): Just posted an answer with the workaround i use.

Things to try after that in the near future:

  • Send an email for official support at Canon.
  • Any suggestions from others witch not included here.

Print tests

2 is the desired density (windows). 3 is what gets printed with Ubuntu and Toner Save: OFF and 1 is with Toner Save: ON

  • I wonder which printer driver you use; Canon recommend their UFR from here support-asia.canon-asia.com/contents/ASIA/EN/0100595001.html and I can supply a how-to if you wish

  • as in here ubuntuforums.org/showthread.php?t=2373655, the file is linux-UFRIILT-drv-v140-uken.tar.gz and if saved to a Downloads folder, the commands in sequence are cd Downloads then tar -zxvf linux-UFRIILT-drv-v140-uken.tar.gz then cd linux-UFRIILT-drv-v140-uken then ./install.sh

Workaround Solution (with cloud print)

The only solution i found is to install a google cloud printer. I did this following the question: How can I easily set up a Google Cloud Print printer?

Since this printer is not "cloud ready" a windows PC has to be online so i can print with it's drivers.

Fortunately enough we have such a PC in the office (on air PC) so i installed cloud print on it following:

Set up your printer with Google Cloud Print

I could have done the same thing through sharing a windows printer but with this solution i can print from my mobile (or any device) from anywhere (as long as the printer is powered).

The out come is exactly the same as if i am using the windows driver, so everything is fine for now.
