Re: [Qgis-user] Scale on printed pdf is incorrect
This is the reason I always recommend to people to use a scale bar rather than a specific numeric scale, you are safe no matter what the printer (or people) do to your masterpiece.

Re: [Qgis-user] Scale on printed pdf is incorrect
Hi Flore, I just did a test on a 1: 2000 scale map I printed from QGIS 2.18.24 in QGIS (whit snap active) the measurement between two points is 67.658 m, on the pdf the same measurement (without snap) is 33.802mm. The difference is only 0.027mm and is probably due to the absence of a snap in the pdf reader.

Re: [Qgis-user] Scale on printed pdf is incorrect
Hi Flore, Are you absolutely sure that the printer is not scaling during the printing? Many printers "autoscale" and shrink the content, because they think that there is content right to the edge (even if it is just white-space). In such case, you can often force the printer to turn off auto-scaling through some printer setting (e.g. print at 100%). Another source of confusion regarding printing at scale is the coordinate system. What coordinate system is your data in and what coordinate system are you using in your project? Anything lat/lon should be converted into a projected coordinate system, before trying to print at scale. If you double checked that and can confirm that it is not the fault of some printer setting, than you should file an issue report at https://issues.qgis.org/ and we can find a developer to look at the issue. Best, if you could provide a sample data and project to reproduce the issue.

[Qgis-user] Scale on printed pdf is incorrect
Hi, I have a problem with printing a map on the right scale (Qgis2.18.24). If I put the map in the print composer on an A4 format, I change the scale (for example 1000), and I print the pdf, it is printed on the right scale. (I recalculated it, by measuring a specific distance in qgis and then on the pdf). Now, our map is very detailled and we need those details in good quality. So we need to print the map on format A0, to have the best quality. If I do the same as before (change scale, print on pdf), the scale isn't right on the pdf. Instead of scale 1/1000, I get some scale in my recalculation. Do you know what the problem is, or what did I do wrong?
