I am looking to print my drawing on Librecad. I want a 2.5 cm line from the drawing to be translated as 2.5 cm on the paper. Selecting the scale to be 1:1 doesn't work. I am using A4 paper. Can anyone help me out?
What is the result then? Does the drawing fill up the whole page? Or is it a slight deviation? Does it look right in Print Preview? Do you use Print Preview at all? You have to stay in Print Preview mode when hitting the Print button. Have you set this 1:1 in your printer's driver configuration or have you set fit to page or within the print margins there?
More details please.
