Print to screen (often abbreviated “PRT SCR” as, “Print SCRN”, “PRT SCN”, “PRT SC” or “PRNT SCRN”) is a key present on most keyboards. It is usually located in the same section as “break” and “scroll lock” key.
While in the new generation of operating systems that use graphical interface, it is very easy to make a screenshot (bitmap image) of the clipboard and save it to an appropriate storage location that can be inserted into documents as a screenshot. Some shell commands allow different use changes, using different keys such as CTRL.
In Microsoft Windows, pressing print to screen will capture the login screen and in combination with “ALT” key will capture the currently selected window. The captured image can be pasted (paste) in an editing program such as Paint, Word, email or other graphics programs. Pressing print to screen at the same time as “ALT”+”SHIFT” keys will trigger a high contrast mode for people with defective vision.
In environments such as GNOME and KDE, Print to Screen key role is similar to the one Microsoft Windows has. However, a window will appear to save the image to a file (in PNG format).
Macintosh computers do not use the Print to Screen key. In its place, use command-shift-3 sequence, this saves the image in a file on disk. To capture only part of the screen, use command-shift-4 to display a special cursor that can be used to select the desired one. In both ways you can save the file on the Desktop.
On RISC OS computers, Print to Screen key opens a window with options for print, similar to that which appears when you press Ctrl + P in Windows or Command + P on Mac.
We know that when we need help, we go on forums or other sites where we post the question / problem to our administrators or users of that forum. They often ask us to get a screenshot of the error (message) to know what happened to your computer. Besides this screenshot they often need the details about the operating system, and what we did before the error. They may ask also what we installed or uninstalled, how we uninstalled or how we tried to fix the issue. If you ask for help, it is very important to know what operating system you use. For such situations, two applications are very helpful. The first application is Snipping Tool, program that comes with Windows 7. This program enables us to print to the selected screen in any way we want and allows us to make prints of rectangular windows or the entire desktop. We can save it as PNG, GIF, JPEG, and HTML. After that we can edit any item in the picture that we want to highlight, give a specific color to the text or highlight an application button located in the screenshot. Snipping Tool disadvantage is that it cannot do automatic upload of the photo on a sharing site, like giving or sharing of the picture to friends.
The second application requires no installation and it is very simple, unlike the Snipping Tool. After the screenshot creation, it will automatically upload your print to the application server and give us a link that allows us to share. Basically the application will post the link; we just need to paste the link in the Yahoo Messenger conversation window, for example. The application allows us to use our own FTP account if you have one.
These two applications are useful while working on a project for someone and you want to show them in what stage the project is. NOTE: For use “ScreenSnapr” application is necessary to have installed. NET Framework if you use Windows XP
