OP, as the others have said you can choose whatever delivery method you'd like. But watch out for those fees!
I JUST printed my Disney e-tickets about 30 minutes ago and had no troubles at all!
The e-tickets are send as an attachment to your email address. The attachment is a PDF Adobe file, so just open and print. You can open this attachment at any time and print it any time before you leave. You could also foward this email and it's attachment to another person and have them print it for you. Last year my printer was out of ink, so I emailed it to my sister and she printed them for me- no problems!
If you have some time before you are scheduled to leave, then I suggest you go for the e-ticket and find a place or a person to print them out for you. Otherwise you'll have to deal with waiting for the mail or standing in line at will-call AND pay for this inconvience to boot!
Can you email it to someone to print for you? Perhaps print them at work? The library? Or maybe...it's just time to buy a printer??

I can't imagine how you go through life without one, but that's just me.
