There are a few factors to consider when deciding whether to print from a JPG or PDF. The first is the quality of the image. A JPG may have a lower resolution than a PDF, which means it will not print as sharply. The second is the size of the file. A PDF will generally be larger than a JPG, so it will take longer to upload and download. Finally, consider the compatibility of the file format with your printer. Some printers may not be able to print PDFs correctly.
