I don't think you have got the entire point yet so ..... you would not print directly on Royal paper as it is, could you imagine a document where the pages are 20" x 25"?
You could fold it 3 times you get 8 sheets of 10" x 6-1/4" paper, cut along the fold lines and then print on them. This size is called "Octavo" size.
What printers do is lay out the Octavo pages on sheets of Royal paper, print them, fold them and then bind and trim them which reduces the dimensions to 9-1/4" x 6-1/8".
I am going to leave laying out the pages on the obverse and reverse sides so that when the paper is folded the pages are in the correct order as an exercise for the reader (read masochist).
So the self printer needs the following:
1) A desktop publishing program that recognizes "Royal" paper and knows how do create and lay out "Octavo" size pages on it. I doubt many, if any, commonly used DP programs would fit this bill - so a large print-shop application.
2) A printer capable of printing "Royal" paper - can you imagine the size and cost of a printer that can print 20" x 25" paper?
Note: I am assuming that Royal paper is still a common standard size that is readily available in the US, otherwise he is going to need to pay for specially cut paper.
He should of saved himself the time, money and trees and paid the quoted price. If he was determined to do the job properly himself the printer alone would have cost him more than having the printing outsourced, let alone a commercial grade publishing/typesetting program to accompany it.
The dimensions are not arbitrary, just archaic, Royal paper size. Royal is an old (read ancient) English paper size. I used to work in the printing industry but I and the printing industry (except the US obviously) have moved on.
He should have got some "Royal" sized paper. It is 20"x25" paper, that when folded to make 8 pages gives you pages that are "Octavo" (6-1/4" x 10") - they are 6-1/8" x 9-1/4" (after binding and trimming).
It is a bit more complicated than that. It depends on which State you are considering as to whether the Truth is a complete defence or a partial defence.
In New South Wales (I assume the case was there because of the "Sydney Restaurant") the truth is only a partial defence - reduces damages. You need to show that it was the "Truth" and "It is in the public's interest to know" to have a complete defence.
Re:
Agreed!! The sooner every country in the world is on the list the better.
Maybe, just maybe, the US will finally realize that all other countries are sovereign identities and have the right to determine their own laws and other countries (maybe not the politicians) don't give a shit about the US and its "Laws".
As a side benefit, everyone would have a convenient list of all countries, except the US (maybe), on hand at all times.
