You make it sound like this letter is important; you can certainly make the time to rewrite the (presumably) short letter and then put it in front of him to sign it. If you're not going to see him between now and then, just leave the signature off but leave his name and contact information in print for them to get a hold of him to verify the information. Just confirm with him prior to submission that this is acceptable. If he's anything like any boss I've ever had, they'll be relieved that you're doing the leg work, and all he has to do is sign it.
Having both written and requested letters of recommendation, they are no fun to write and no fun to pester others to write. You want to say positive things about the person without sounding overly positive, and if anything they write is remotely negative, they have to worry about getting sued.
