problem reduction measures in printing phase

[xSiMoN]

Hello everyone, I am new here and I pray that I am a 5th-year-old Georgian student. my problem is that when I go to print in autocad 2016 (student version) everything that mold is reduced (for example on autocad I have a size of 39.8 and then when I go to print I go to measure with a line and it is about 38.4). when mold I always put the scale, center print and pdf creator. If someone knows how to solve this problem, I'd be grateful

but it is not that the problem is when you send pdf to the press by adobe reader ? there are various options for printing in adobe, for example "detail", "actual dimensions" "reduce".
verify the size of the autocad set sheets for printing and printing of your printer.

you also have the doubt that the error happens when molding in pdf. can you tell me by chance how to check the settings you told me?
I always mold in a3 and for this format I modified the print area to the maximum that I could eliminate all margins. My printer's settings didn't have to verify why the printer is at my dad's job. I simply send them the pdf and he prints it in the format that I tell him

I think the problem is the elimination of margins.
you print "electronically" on all a3 format without any margin, the file comes to the printer that instead always has a margin.
is a physical fact; the printer must know that the cartridge is inside the sheet to prescind from everything, and this does it simply by reducing the print area of that so much that it compensates for any disalignments during loading of the sheet, movements of the origin of the cartridge etc.)
then you send a full a3 (theoretically a 42cm long line) to a device that handles a3 less x.
now the program with which your father print has 2 possibilities:
1) adapts your segment of 42cm to (42cm-x) reducing everything in scale;
2) print your segment of 42 by cutting the x that does not physically enter the device.
If you tell your father to set the press without adjustments/reductions (so with truncation) you should solve the problem.
but perhaps solve it more easily if you resell your format and the 5-7mm margin around which are physiological in a print.
