Trying to fill out and then email a secured document but I don't own a printer

Hello, I'm trying to fill in and print a document for my health insurance. The form is a protected document that will only open in Adobe Acrobat Reader and won't let you save any changes. I need to send the document to my physician and understand that it's protected so I won't be able to  just email/fax the PDF online (though this would be ideal).

The next thing I've tried to do is print the form so I can just fill it in manually, then scan it, and send to my doctor. HOWEVER, I don't own a printer. There's a store near me that will print but I need to email the document to them for them to print it. Every time I try to get a copy of the blank document by clicking 'Print blank form' I get this error " Before you can perform print-related tasks such as page setup or printing a document, you need to install a printer."

So now I'm stuck and I can't fill in the document digitally and I can't print the document unless I drop $100 on a printer that I'll use maybe 2 times a year. Any advice on how I can get around this?
