Simple Screen Capture (print screen) software

I have a DOS graphic-mode program for which I would like to capture the screen under Win XP. I was not sure from previous threads which program is recommended for this.
Can someone please recommend a program that will dothat?

 

To create a graphics file that contains a screen object, follow these steps:

1. Open the object that you want to capture as an image. Adjust the size and the position of the object.
2. Press ALT+PRINT SCREEN (press the PRINT SCREEN key while you hold down the ALT key).
   
   The image of the active window is captured on the clipboard. NOTE: If you want to capture the object in the context of the entire screen, press the PRINT SCREEN key alone.
3. Start the program that you will use to manipulate and save the image. For example, start Microsoft Photo Editor, which is available as one of the Microsoft Office Tools, or start Microsoft Paint, which is available with Microsoft Windows.
4. On the Edit menu in Paint, click Paste (or click Paste As New Image in Photo Editor).
5. If the image contains a lot of irrelevant content, select the part you want to keep, and then paste it as a new image. To do this, follow these steps:
   1. Click the Select button on the standard toolbar.
   2. Select the part that you want to keep, and then click Copy on the Edit menu.
   3. On the File menu, click New. Click No when asked if you want to save the file.
   4. On the Edit menu in Paint, click Paste (or click Paste As New Image in Photo Editor).
6. Print the image or save it to a file.
