Print screen (often abbreviated Prt Scr, Print Scrn, Prt Scn, Prt Sc, Prt Scrn, or Prnt Scrn) is a key present on most PC keyboards. It is typically situated in the same section as the break key and scroll lock key. In Microsoft Windows, pressing Prt Sc will capture the entire screen, while pressing the Alt key in combination with Prt Sc will capture the currently selected window. The captured image can then be pasted into an editing program such as a word processor or graphics program. Pressing Prt Sc with both the left Alt key and left ? Shift pressed turns on a high contrast mode (this keyboard shortcut can be turned off by the user). (wikipedia)
Print screen digunakan untuk mengambil gambar laman yang ingin Anda simpan. Tekan Print Screen di keyboard dan paste di paint atau di photoshop. It is simple dan seharusnya sudah familiar digunakan untuk mereka yang berkutat di komputer sehari-hari.
