ODS version + pdf version

I exported my Calc to a pdf format and the scale changes along the horizontal axe.

Enclosed, my ods. file where I put some vertical lines of width 21cm/20=1.05cm. Consequently, there are 2 lines (the first and the last) which are on the border. This is what we can check in the .ods file when looking at the ~"before printing view" for example.

But, when exporting to pdf (enclosed my pdf file), the last line is not yet exactly on the border (1-2 mm from the border), while the pdf file informations say that the width of the pdf is 21.0cm. It means that a rescaling has been done. I also check it by measuring the interval between the lines which are tnot the same yet.

I would say it's a general printing problem because it's the same when printing it directly from the ods file to the printing machine (I checked it by measuring manually the line width on the sheet of paper).

Finally, there is the same problem with the Calc from the Linux version 3.2.
