Bill originally contained different tax on printer (7,6)

I believe the answer is:

william caxton

'printer' is the definition.
(15th-century printer of books in England)

'bill originally contained different tax on' is the wordplay.
'bill' becomes 'william' (Bill is short for William).
'originally' says to take the initial letters.
'different' is an anagram indicator.
The first letter of 'contained' is 'c'.
'tax' is an anagram of 'axt'.
'william'+'c'+'axt'+'on'='WILLIAM CAXTON'

(Another definition for william caxton that I've seen is " printer - with 8a".)

I've seen this clue in The Times.
