Created attachment 70614 [details] small page document with a symmetrical table I put a table with a single cell into a new document. I set it to be aligned to the centre and I define symmetric margins on the page. I suppose the table should be centred on the page. In contrary, it is shifted a bit left. To illustrate this I created a funny document. Page size is 0.7cm both horizontally and vertically. Margins are 0.1cm whole around. I attach the odt document and the exported pdf as well. The reason for so small document is the visualisation of the asymmetry via zoomed view of the whole document. Therefore I attach a screenshot of the pdf viewer as well. I indicated by red symbols that the two margins are not symmetrical. I think under the detailed circumstances the pdf file should be symmetrical.

Such asymmetry occurs for A4-sized page too. I used 70x70 page size instead of 297x210 in order to visualise the whole page in one screenshot. It would have been much more difficult to use A4 sized page with this zoom level in the pdf viewer. The measure of asymmetry seems to be insignificant but if I print two symmetric tables on two sides of a sheet then corresponding table lines from the opposite side should coincide with each other. Unfortunately they do not, so if I slice the sheet according to the lines of one side then the lines of the opposite side will remain visible.
Sorry that you had to wait such a long time for a reply. With the naked eye I could not recognize any asymmetries (LO 4.1.4.2, Win8). Does this issue still persist for you with the latest release of LO? How did you measure your recognized shift?

Hi, sorry for not responding for so long and thank you for the reminder. The newest version I have is 4.1.4.2. It still produces the symptom. However, this version is able to create smaller page which is better for this illustration. I created the three attachments. The first is the original ODT document, the second one is the PDF which was exported by LO. The third one is the PNG screenshot about the Foxit PDF Raader as it shows the PDF document. It is easy to see on the latter one that the left and upper border are more thin than the other two borders. Obviously, nobody prints a page in 45x45 millimetre size with 0.1 mm border. This is just for illustration. Originally I realised it with an A4 size page where the difference is bigger. I printed two opposite sides of the same sheet. If the margin width is the same on the left and right side then the lines should cover each other. I was wonder if my printer's mechanical characteristics is responsible for the misalignment between the two sides of the page or the printed documents differ. Surprisingly, it turned out that the pdf version of a LO document having symmetric margins is not symmetric.

I reproduced. Changed component to Printing and PDF export, because the document is ok when viewed in Writer. Win 7 64-bit Version: 4.5.0.0.alpha0+ Build ID: 772befa08f02b08da1ab493896a0744bc73781c7 TinderBox: Win-x86@51-TDF, Branch:MASTER, Time: 2014-11-23_22:39:02
