Here's a tutorial for you:
1 - Download the program by clicking on the link. Save it to a folder so you know where it is. (I saved mine to c:\download.)
2 - Run the roundball.exe by clicking Start, then click Run. When the window pops up, type in "cmd", then click OK.
3 - This will bring up a "Command Window". Type in "cd \download" (substitute download with the folder you saved the program to), then hit Enter.
4 - Type in "roundball" and hit enter. This will run the program you downloaded.
5 - Follow the instructions on the website and run the program to get your ballistic information.
6 - Put your mouse pointer on the very bottom edge of the command window, and the cursor will change to a small black arrow that points up and down simultaneously. Hold down the left mouse button, and pull the mouse towards you to make the window large enough to show all of the ballistic data at the same time. Your window should look something like this:
7 - Now that your data is on the screen, hold down the Alt key, and press the key that says "Print Scrn SysRq".
8 - Click on Start, then click on Programs, then click on Accessories, then click on Paint. Once paint comes up, hold down the Ctrl key and hit V. This will paste the screen print into paint. You should now see something like this:
9 - On the menu at the top of the Paint window, is a menu titled "Image". Click on the word Image, then click on "Invert Colors" on the menu that pops up. This will change the black to white, and the white to black. You should now see something like this:
10 - Now, you can click on "File", then click on "Print", and print out your data from the program and it won't use up all the ink in your printer and look like something out of a bad horror movie. :redthumb:
