There are a few different ways to prepare your artwork for print. The first is to save it as an image file. Image publishing software and/or vector drawing software can be used to create a PDF or JPG file of your artwork.
Another way to prepare your artwork for print is to create a vector file, then copy the file directly into Adobe Illustrator or InDesign. Both programs have capabilities to save files as vectors, which makes it easy to resize and adjust the overall size of the image without losing quality.
