screenshooter - 'Open With' and 'Copy to Clipboard'

When taking screen shots, I tend to want to postprocess them immediately.

Maybe a quick crop, or if the screenshot is to end up on blogger, choosing the jpeg output format (see notes at foot of this posting)

This is why xfce4-screenshooter is my preferred screenshot tool

...as 'Open with' GIMP Image Editor is usually how I go about things.

Here is the menu option for xfce4-screenshooter on Ubuntu Lucid:

If you run Gnome rather than Xfce then, you will maybe, by default have Gnome screenshooter tool.

...which has 'Copy to Clipboard' in the dialog window, popping up, when you have clicked 'Take Screenshot'

Using 'Copy to Clipboard', then from within GIMP, Edit -> Paste As -> New Image ... would also get your screenshot into GIMP for post processing. Just seems a slightly roundabout way when xfce4-screenshooter does it directly.

Note: If you have both screenshot tools on your system, then you might want to 'Edit Menus' to adjust your Applications/Accessories menu to only display your favourite of the two :)


Png and Jpeg for Blogger posting and resizing:

When using blogger, i have little control over how the image is embedded in the page, other than selecting small, large, x-large, etc.

I may be that google resizing process is less than ideal for .png files. Experience suggests
to me that when using blogger jpeg images are not as badly affected by google resizing process.

Having images appearing as grainy due to prepublication resizing just looks a little sloppy, and
so until I understand more, it looks like I'll be using jpeg when posting to blogger. From the little bit
of reading that I have done, it seems that Google really does have a leaning towards jpeg rather than png when you interact with Picassa and Blogger.


Image viewers versus Image editors:

I really am in the keep image viewers as image viewers only camp, when it comes to things like Eye of Gnome, or the feature creep that makes an image viewer into an image editor/photo manager.

I recognise the desire to make things easy for the end user, but I tend to avoid Gthumb and F-Spot and things that supposedly 'manage' images, and instead select my own tools to get the job done.

Debian Squeeze printing and Samsung Laser (Splix)

When using Samsung ML-2510 with Cups and other printing systems for Linux, you will need to have the splix drivers installed.

These Splix drivers are in the repositories, and are separate to regular cups packages for the following reason:

Cheap and cheerful Lasers like Samsung ML-2510 do not use standard printer languages such as Postscript or PCL. Why Samsung have to be different is beyond me, but in any case, the solution is to install splix.

apt://splix

[ Above apt:// will take you directly to the package if you are using mozilla browser and have aptlinex (Debian) or apturl (Ubuntu) installed ]

( If you are a Mac user and find that your operating system has left you without a suitable driver after your OSX upgrade, then feel free to download the splix source or Debian .tar.gz both of which are licensed under GPL. It would be appreciated if you might remember in the future that GPL software, exists on your system, and helped your system, where your vender support proved insufficient. Enough GPL bashing please. )


Debian light desktop and ML-2510 plus 'Print to File':

On my debian desktop I prefer a light window manager (Xfce) and so I will be exploring how to setup printing without pulling in Gnome/KDE stuff where possible.

I already have xfprint4 installed but this is a frontend is not in itself enough to print, without some sort of backend/daemon such as cups.

apt-get install task-print-server splix

Now task-print-server has pulled in cups, and so a printer daemon/backend is now installed on the system.

( Older Debian systems had a package called printconf
that may have been used instead of task-print-server )

There is a further step now because this Samsung needs more than a standard cups driver - as Samsung Lasers uses Spl2 proprietary printing language.

What you are aiming for is this:

...which indicates that cups have a usable .ppd file for Samsung ML-2510.

To get to that result, you are going to have to interact with cups a little (see below) or you might try just a straight file copy should you feel adventurous.

...and choose your options...

...and setup is pretty much complete.

You might wish to have your system capable of a .pdf output directly from the printing system ( not to be confused with Mozilla browser 'print to file/pdf' )

apt-get install cups-pdf

Something to remember, is to set 'Server Default' properly, if you have several output choices on your system. That way your system knows which is your preference.

The key piece in the above screenshot is the text Server Default)

Additional information about Mozilla browser 'Print to file/pdf':

Mozilla Browser (Firefox) has it's own way of outputting .ps or .pdf files that is independent of your printer server.

( Mozilla relies on libcairo2 vector graphic library for it's 'Print to file/pdf' )

Here is a screenshot that might be familiar to anyone who uses 'Print to file/pdf' or 'Print to file/ps' from Mozilla Firefox.

To clarify further, that 'Output format' radio button choice (PDF or Postscript) is very specific to Mozilla Firefox and is not system wide.

The above crop shows a dialog portion which you will only encounter in Mozilla Firefox, and so do not expect to see that in OpenOffice or elsewhere.

OpenOffice has its own 'Export to PDF' option should you wish to go that way.


Notes and Further Reading:

I have used Mozilla Firefox and Iceweasel (Debian) interchangeably in this article as the actual package name is not an important part of this article.

Splix V 2.0.0 drivers are in Debian 7 (wheezy) and earlier release (squeeze)

• Configuration Screenshot for Energy Settings [ splix.ap2c.org ] 
• Using devices that take advantage of JBIG compression and Corporate Setting

The Samsung ML 2510 which I own, does not require a module that supports JBIG compression, however some of the other Samsung SPL2 printer language printers do.

There is much to read about JBIG and JBIG2 if that interests you. Some points:

• All patents have now expired for JBIG (JBIG1)
• JBIG compression system includes no active patents now
      [ wikipedia.org ]
• JBIG2 is very different to JBIG1 and does have active patent filings.
• Pdf standard 1.4 may include data compressed with JBIG2
• JBIG kit download [ cl.cam.ac.uk ]

Many software packages are capable if producing output to the Pdf 1.3 standard, that is one way to avoid the possibility of requiring the receiver having a Pdf reader that needs JBIG2 decompression support.
