if you email the document to be printed as an attachment from your "home" computer to wherever you are using as the control computer, and then print it from there you can get round this limitation. you can use dropbox as already stated, or "drag and drop" the document into skype to the message box which does file transfers of everything up to very large files easily.

there are lots of ways around it. if you are working on a machine without your normal mail program, then have a webmail address (hotmail, gmail, yahoo etc) which you can open in a browser window too.
