How to print with blender and make it png

on how do i print when ive made something in blender
and how do i change the file to png so i can host it on the intenet
Thanks in advanced

Press F10. The panel on the far right has a drop-down menu which allows you to choose the file type (jpeg, png, tiff, avi, etc.).

Render your image as usual.

Press F3 to get a ‘save file’ window (you may have to drag down the top menu bar to see it).

When you specify a filename, don’t forget to add the file extension (for example: my-image.png).

Now you can upload it to an internet host, like mudpuddle.

Blender cannot directly print the image to paper. You’ll need another program like Photoshop, Gimp, IrfanView, MSPaint, etc. (If you don’t have one of those, you can use MSWord or OpenOffice, but you’ll get better results with one of those dedicated imaging programs).

Hope this helps.
