canon interview questions
Top canon frequently asked interview questions
I just bought a Canon MG5250 multifunction printer because I thought that it would work well with Ubuntu, but it's hard to get it to work.
How do I install this printer?

I have this Canon LiDE 200 but simple scan cannot use it properly. With the new sane-backend from rober-ancell's ppa the scanner head at least moves a little, but simple-scan simply fails telling me that the scanning fails in a red banner below the menu bar.
Is there some way to get it to work?

I tried to install the MP190 drivers, but appeared a message show me that requires to have libcupsys2. I understand that libcup2 is an update of libcupsys2.
How do I solve this? Are there proprietary drivers for my Canon printer or scanner?

I downloaded Linux CAPT driver V2.60 from Canon and installed both .deb packages, which were listed under the 64bit folder with Ubuntu Software-Center. My Canon printer still won't be recognized. Is there anything else I have to do? My printer is connected over USB.
Ubuntu would make a great replacment for my office, but unfortunately without printer support I will still rely on Windows.

Recently I had one of the most frustrating experiences with my printer.
I sent a some print jobs to my Canon Pixus iP3100 printer, but then realized there was a problem with the layout, and so I wanted to kill the print jobs. I went to this interface:
However, pressing the stop button, marked with the square, did nothing.
I tried everything I could think of to kill the print jobs. I tried restarting the printer. I rebooted the computer. I hit "reset" on the printer. I tried killing any printer related tasks in the task manager.
No matter what I did, though, the same jobs were in the queue, and the only way in the end that I was able to get past them was to have them all run through to the end.
Is this a bug, or is there some other aspect to this that I am missing?

Initially this question was limited to 11.10. Now I am in (Lubuntu) 12.10. (On the changes in the question see this meta question).
Considering 11.10
I have tried different (or not so different) approaches - that also other users commented here. My main references were:
None worked for me.

I am running Ubuntu Oneiric 11.10 on two computers, one is AMD-64bit architecture, the other i386--same problem on both. In 11.04 I could print and scan just fine, after some tinkering, but after a fresh install of 11.10, adding ppa:michael-gruz/canon, and installing cnijfilter-mx860series and scangearmp-common from the PPA, Ubuntu's system-config-printer cannot detect my network printer.
In the previous installation it appeared as cnijnet://printers-mac-address. I know it should be able to see it because I can ping the printer at its IP address, I can browse the printer's web admin page from the computer, and my Windows guest in VirtualBox on the computer has no problem detecting and installing it. It seems like this problem is new to Oneiric. How I can find my network Pixma again?

I am using a Canon MP280 printer, which I found a driver from canon on the european site for. The print dialogue does not allow me to print in black and white unfortunately. Does anyone know of a way for me to force this? I'm guessing it is just a fault with my printer driver, but I feel like greyscale printing should be something in the OS sending the job, not in the printer drivers part.

I have a canon PowerShot A3100 IS camera, and, as written in the title, I wanted to know where does the automount mount it when I connect it.
Does anyone know ?
thank you,

At work we have a Canon C5045i printer, for which Canon provides three PPD files: ps, pcl, and pxl.
Is there any one that is preferable over the others?
Is there any difference between the three?

I am unable to setup Canon InkJet Pixma IP 1300 on Quantal AMD64. The things I have tried:
- Shut down and disconnect the printer before installing packages.
- Added the
ppa:michael-gruz/canon repository to synaptic and installed the cnijfilter-pixmaip1000series package (there is no package for 1300 so I installed the nearest one). The PPA repository does not have packages for Quantal, so had to manually update the repository definition to "Oneiric" and refreshed it before downloading.
- Restarted cups via
sudo service cups restart.
- Connected and switched on the printer.
- Opened All Settings -> Printers to Add a printer. There are 2 entries - One for the Standard USB Printer, another for "USB Printer - With Status Readback for Canon IJ" with Device URL as
cnijusb:/dev/usb/lp1. Have selected this as per direction in Ubuntu Community Forum.
For manually entering a .ppd file I select /usr/share/cups/model/cnpixmaip1000.ppd.
ERROR MESSAGE : Failed to read PPD file. Possible reason follows:
/usr/share/cups/model/cnpixmaip1000.ppd: FAIL*FAIL* Unable to open PPD file - No such file or directory on line 0.
On checking I find that cnpixmaip1000.ppd file in /usr/share/cups/model is a symbolic link pointing to /usr/share/ppd/cnpixmaip1000.ppd.
However the later file does not exist. There are no other ppd files installed.
PS: Printing works fine with the shareware TurboPrint for Linux. So, there's nothing wrong with the printer.

I have a Canon LBP2900 printer and Ubuntu Natty 64-bit.
After quite some trouble I found here a nice guide explaining a installation procedure with packages from this ppa.
I followed the guide and did all steps and now the printer works if it is connected (or powered on) after login.
If I connect it already before my computer is started, the following happens. A second printer (LBP2900-2) is automatically created and the command sudo /etc/init.d/ccpd status only gives one pid, while it should give two.
How can I fix this?
An extra detail that can help; normally the device uri is ccp:/var/ccpd/fifo0. Actually this path (/var/ccpd/fifo0) does not exist, but that does not seem to matter. The printer that Ubuntu automatically adds when starting up with the printer connected has usb://Canon/LBP2900 as uri

The Canon S110 comes with an optical disk containing a software bundle for Windows (and of course nothing for Linux), including an utility for connecting to the computer through WiFi.
Also I think worth noting is that in Windows the transfer process requires Media Streaming and Network Discovery to be turned on. I think this would be key points for enabling photo transfer on Ubuntu also, but I cannot find [the equivalent of] these options anywhere.
This link explains the process for Windows.
So the question is how can I transfer my photos from the camera to my Ubuntu PC over wireless?
I love the wireless option on the Canon S110 and have been using it intensely before switching over to Linux, I don't like to mess with cables. Anyway, I already lost the original cable. Also my PC has no card reader.
I am using both Xubuntu and Mint 16 XFCE.
