SOLVED Canon Maxify MB2720 prints negative (whites are black)

[lumetters]

Before reinstall of Mint 18.3 and before Canon sent me a replacement printer, a similar model printer printed correctly via wireless. The oddity now is that the printer prints a web page with black areas as white and white areas as black. I like to think I have an incorrect setting and not a problem with the Mint 18.3.

A Print head test page started from the printer looks good.

Trial and error by me got the printer to print something from this laptop. My solution is not right, however.

Settings:
Description: Canon MB2700 series
Device URI: dnssd://Canon%20MB2700%20series._ipp._tcp.local/?uuid=00000000-0000-1000-8000-F4A997596ECA
Make and Model: Generic IPP Everywhere Printer
Printer State: Idle - Waiting for job to complete.

Printer Options: Color Mode: Grayscale (8 bit)

Ink/Toner Levels Refresh clicked generates "CUPS server error" There was an error during the CUPS operation:
'client-error-document-format-not-supported'

Linux and CUPS are new to me in the last year. I started with DOS 2.1, but won't go back to Windows 10 or anything Microsoft on this computer.

can I suggest you install the drivers that Canon supply for the MB2700series; and see how that goes?

If you go here https://www.canon-europe.com/support/co ... anguage=EN

and click to download and save what will be cnijfilter2-5.20-1-deb.tar.gz

if you open a terminal; copy each line of command one at a time; paste into the terminal; hit the ENTER key; move to next command

Code: Select all

cd Downloads

Code: Select all

tar -zxvf cnijfilter2-5.20-1-deb.tar.gz

Code: Select all

cd cnijfilter2-5.20-1-deb

Code: Select all

sudo ./install.sh

and that should create a new entry ........maybe called MB2720USB ? ....... how does it do?

Your current MAKE & MODEL entry says

Generic IPP Everywhere Printer

...seems to me that is fairly generic

Thank you, PDC_2:
Your helpful post pushed me to delete the printer I'd installled and start again. After downloading the same driver as the first time I opened up the un-archived file and found the 64 bit driver and discovered it was an installer. I clicked it and the install process took a few seconds plus locating the 192.168.0.102 address of the printer's WiFi.

Printer and this computer connect and print normally. ... no color reversals.
