To open an image file click on the 'plus' (+) sign.
After you have opened the image, click on the next icon to the right to run OCR.
After is has finished OCR'ing the image, you can select the text you want on the ...

The idea of having a simple scan utility was behind the development of, well, Simple Scan - the scanning tool installed by default from 10.04 on (Applications ‣ Graphics ‣ Simple Scan).
Simply scan as many pages as you want and choose PDF as file format when saving.
Another slightly less simple program that offers additional features like text ...

You can't edit text in a JPG, but you remove the text and add new text.
For images, try gimp (open source alternative to Photoshop). Open the image with gimp, then use the eraser tool to erase the old text. Then use the text tool to add new text.
Or, use inkscape, which is a vector graphics program (similar to Adobe Illustrator). Create a new SVG file and ...

sudo iwlist wlan0 scanning | egrep 'Cell |Encryption|Quality|Last beacon|ESSID' should help.
It's the combination of sudo (run as root, do privileged operations), iwlist wlan0 scanning (produce some output on STDOUT), the pipe symbol "|" (connecting STDOUT of the command(s) to the left to the STDIN of the process on the right), and an egrep command with a ...

Try this
sudo ufw logging on
You should see access in /var/log/syslog. But this are raw logs, which only show you individual access. UFW itself hasn't any tool to summarize these access to an useable report. Also I don't know about a tool which can do this.

Thank for the info. I think the following lines does the job (for the brscan2 package) - Ubuntu 12.04 amd64, Networking DCP-560CN:

sudo cp /usr/lib64/libbrcolm2* /usr/lib

Regarding the removing part...
simple-scan is for scanners. <600kb on disc. system-config-printer-gnome is for configuring printers. 1.6Mb on disc. It is part of the gnome desktop though so might not be that easy to get rid of. cups 1.5.0-8ubuntu6 is 8Mb. It might also be a hassle to remove since it is sort of a system wide system all programs that have ...

scanimage is installed by default.
And here's me using it:
oli@bert:~$ scanimage -L
device `epson2:libusb:002:003' is a Epson PID 084F flatbed scanner
oli@bert:~$ scanimage -d "epson2:libusb:002:003" --format tiff > rawr.tiff

I just delved into the packages, they do provide a sane module for canon multi-function scanners. And the second package does contain the right files.
Firs thing though, cd dpkg -i is complete rubbish, that's not a valid command and would never work no matter what. I'm editing it out of the other answer so other people aren't confused by it.
I would get ...

I was using xsane until I saw this question and considered its interface idiosyncratic to say the least, but effective.
Upon seeing this question I went looking and found gscan2pdf living in the Ubuntu Lucid/Maverick repositories. It uses the same scanning (libsane) engine but the UI is far more Gnome-ish. For a good time, try:
sudo apt-get install ...

If your scanner doesn't work with simple scan, it is probably best to install the iscan package. The following general instructions will work for your model and any other ones listed on the site.
It is worth explaining in detail which packages to choose as the download site is quite confusing. As noted in the comments by JoZ3 the preferred site is now the ...

You could play around with ImageMagick's montage tool. You'll want to install the imagemagick
package before you go any further.
At face value, you just need to ply montage with input files and then give it an output file:
montage scan1.jpg scan2.jpg output.jpg
but montage can get really powerful. You can pass along various translation arguments if you ...

cron and rsync would be my tools of choice. I'm going to assume you've mounted this network share through naultilus or another method. There are other, better ways to mount things than through Naultilus (especially for scripting purposes) but I'll leave that up to you:
Open a terminal and run crontab -e. You might be asked to select an editor (nano is ...

Ok here is how I got my MFC-295CN scanner working.
I downloaded the drivers, prerequisites, brscan3 ect and installed using software centre. I also installed Xsane. Scanning did not work with Xsane and simple scan.
So I edited the rules.
Open /lib/udev/rules.d/40-libsane.rules file.
Add the following two lines to the end of the device list. (Before the ...

I have jet to find a scanner, that Ubuntu has no drivers for. Most scanners use a standardised USB interface similar to other hid devices such as keyboards, mice etc. If you want to be on the safe side choose a scanner mentioned in the SANE project's supported devices list.
As for applications: SANE handles scanners in Ubuntu. They all revert to SANE. ...

Your model number isn't specifically listed here, but if you want to try there are several .deb files you could attempt to install to get this piece of hardware working. It'd be a total shot in the dark, but it may be worth your time.

A while ago evaluated the various OCR packages in Ubuntu, found that Tesseract was the least bad of them (but bad enough), and wrote a wrapper script for the OCRing (since Tesseract wants obscure input formats like TIFF). Here's my ~/bin/ocr:
#!/bin/sh
# usage: ocr filename.jpg
if test -z "$1"; then
echo "usage: ocr filename.jpg [...]"
echo "needs ...

It finally works!
I evidently made a mistake when first following the tip on the Brother web pages copying a number of library files from /usr/lib64 to /usr/lib. I discovered this by accident when playing with the Ubuntu 12.04 beta 1 in a VM. Since that version is an LTS, I now know that Ubuntu will support scanning with my DCP-315CN for longer than the ...

I found a non-ideal solution, but a very effective one.
I use PDF X-Change Viewer through Wine. It has an OCR feature which adds a text layer to the existing image-based pdf.
Thus you can search and copy text from this invisible layer.

Lexmark supports this printer with linux drivers. Use this link to install the latest version.

Then sane should work.
You may also need to add yourself to the lp user-group.
I would also check for a file in the /.sane/xsane folder for a file name like Lexmark:S505.drc, this would be the scanner configuration for SANE.

My advice would be to simply disable cups.
sudo mv /etc/init/cups.conf /etc/cups.conf.disabled
Or you could edit /etc/inti/cups.conf and comment out the start line (s).
#start on (filesystem
# and (started dbus or runlevel [2345])
# and stopped udevtrigger)
stop on runlevel [016]
