Added the code with a web2py example project at

Yes, your are welcome, thanks!

If you don't broke anything, you can just commit the changes ;-)

Please create a scripts directory for pdflabels.py

A wiki page explaining how it works would be good.

Code changes committed in rev 208314825f21
I'll upload an example of use and a wiki page asap.

When I tried to use it, the Avery-5160 did not format correctly.  I got it to 
work by changing it to:

'Avery-5160':{'paper-size':'letter', 'metric':'mm', 
'marginLeft':6.762,'marginTop':12.7,'NX':3,'NY':10,'SpaceX':3.175,'SpaceY':0, 
'width':66.675,'height':25.4,'font-size':10}

I believe the marginTop was a typo during inch-mm conversion from the Avery 
specs.  The marginLeft may have been okay, but all of the labels were left 
justified.  Not sure if that should be changed in the code or not.  The 
font-size is a personal preference.

I can not confirm it because I don't have that avery paper. I based this  on 
http://fpdf.de/downloads/addons/29/ . The differences between both values don't 
match with a inches-mm conversion error. Now I have found 
https://github.com/lsolesen/fpdf/blob/master/examples/label/PDF_Label.php that 
adds some improvement to the previous code, but it still keeps the same margin 
values.
Is there any source with the right values that we can trust?

This page is the second result when doing a Google search "python avery 
labels". So, if someone else comes here wanting a straightforward how-to, 
here's what worked for me:

1. pip install fpdf
2. Download 
https://raw.githubusercontent.com/jredrejo/Labels-for-pyfpdf/master/pyfpdf/pdfla
bels.py into your working directory.

Example code:
    import pdflabels # pity this can't be merged into the fpdf package

    pl = pdflabels.PDFLabel('Avery-5160')
    pl.add_page()
    pl.add_label("%s\n%s\n%s\n%s %s"%("Joe Blow","123 Main St","Anytown","Anystate","XY 12345")
    pl.add_label(....)
    pl.output('addresslabels.pdf', 'F')
