where can I find a form 64-8 to complete onscreenand print?

Previously I completed 64-8s and other forms using the HMRC CD-ROM. I can no longer use this on our new IT system. It is not possible to type on the form on the HMRC site so I am reduced to printing them off and handwriting the details - not very professional. Does anyone have a link to HMRC forms that can be completed onscreen and then printed, in the same way as for Companies House forms? Yes, I am aware that we could go down the online route, but many of our clients are often away for months on end and the authorisation codes would expire before their return, hence we are sticking steadfastly to the paper route (until that is taken away!). Hopefully someone can help as I have not been able to find anything on the web.
