I found that in adobe reader it take "fit in page" option as default so it zoom my PCB files by 250% ,when I unchecked it and select "actual size" option then I found it OK (1:1). Though still I don't print it after that I will confirm you about this.
@Dillon thanks for quick reply
are there settings I must change on the acrobat reader before printing?
