center/line wrap w/variable width fonts

We have a recent post on centering text, but my problem is much more complex.
I'm printing text using various typographic fonts, mostly Times New Roman (font 
2308 and
2309 for bold), at various pitch sizes from 9 thru 14 in DDS print file type 
*afpds. 
I need to center or line wrap that!
So centering needs to be based on not only character count, but width, and 
different
between pitch size & upper/lower. Need to output professional looking contracts 
and letters, which are converted to .pdf for web printing. This is running 
currently now,
but looking ragged at the end of each line in a paragraph. this is like 
a MS Word function in an RPG program. Other than assigning a value (to 
accumulate)
for each character within each font & pitch size, .like at pitch 10 character 
'A' = 1.00 
and character 'a' = 0.75.. at pitch 11 'A' = 1.10 and 'a' = 0.85 .... any other 
ideas?
 
btw-this used to be handled by Officevision to print till the .pdf requirement 
was added.
Using Gumbo software to convert *afpds spool to .pdf. V4R5, no Domino (and no 
budget). I know of a few MS based products where iSeries could send data to MS 
Word
on server, assume it could convert .pdf, then web serve or print that ((owner 
won't spend
many thousands for a product to connect a pc software & server)). This needs to 
be 
totally hands-free, with no tech to watch, up 24x7x365 (like it is now with 
RPG).
Does the new Infoprint Server in 5.1 or 5.2 offer any features for this? any 
print API's for line wrap?
