The "Print Scrn" key is certainly familiar to those who have been using computers for a while or who write computer tutorials online, as it is a free and built-in screen capture key on the keyboard. However, using the Print Scrn key isn't always convenient because it often requires pairing with other graphic software, such as Paint. If you're just capturing one or two images, it might still be a good option, but when you need to capture a large number of images, it becomes very inconvenient.
Screenshot Captor would be a great alternative. Not only is it free, but it also retains the old habit of using the Print Scrn key. After installing Screenshot Captor, you no longer need to open Paint or any other graphic software to collect your captured screenshots. Once Screenshot Captor is running, it automatically gathers the screenshots captured by pressing the Print Scrn key and immediately saves them as image files (with four built-in image file formats).
