1st line: XXX9Xtext string X is a space character
2nd line: XX10Xtext string

I cannot illustrate it here but the problem is that on the printout page the "9" is not above the "0" in "10" but between the "1' and the "0" in "10" it's shifted 1/2 character to the left. My understanding of the format string is that it should always place 4 character slots on the page, placing the integer as is appropriate and should not attempt to "center" or whatever it's trying to do. Since I am using a constant width font the characters should stay put, in the slots provided.
