If you need to print a picture larger than its normal size, you have two options: use software to make the image bigger, or tell your printer to scale the image before printing. By scaling pictures instead of physically resizing them, you save time and leave the original image files intact. The Paint program that comes with Windows 7 allows you to use digital scaling to make your printed pictures larger.
Click the Windows Start menu button and type "Paint." When the "Paint" icon appears, click that icon to launch the Paint program.
Press "Ctrl" and "O" to open Paint's file selection window.
Find the image you wish to print and double-click it. Paint will display the image on its editing canvas.
Scale and Print Image
Press "Alt" and "F." A drop-down window opens.
Hold your mouse cursor over the "Print" option to open the "Print Options" dialog.
Click the "Page Setup" option. Paint opens the "Page Setup" window.
Locate the "Scaling" section, and click "Adjust To." Type a percentage value in the "Normal Size" text box. For instance, if you wish to print the image at 70 percent of its normal size, enter 70. Click "OK" to close the "Page Setup" window.
Press "Ctrl" and "P" to open the "Print" window. Click one of the printers in the "Select Printer" section and click "Print." Paint will send the image to that printer and adjust its size to match the value you entered in the "Normal Size" text box.
To see what the printed image will look like before printing it, press “Alt” and “F.” Hover your mouse cursor over “Print,” and then click “Print Preview” to open the “Print Preview” window. Click “Close Print Preview” after previewing the image.
