If you can embed your fonts before you send your files over for printing that would be ideal.
What happens to fonts that aren’t embedded?
When you supply your files without the fonts embedded it can cause issues when they're printed. If we do not have a particular font that you have used, the document may default to a standard font like Helvetica or Courier New when printed.
This could dramatically alter the appearance and layout of your document and is therefore best avoided.
You can learn how to embed your fonts in our Embedding Fonts section.
