Download the free Adobe Acrobat Reader DC software for reliably viewing and printing PDF documents. Do not use Mac Preview, your internet browser or the version of the Adobe reader that comes with the Windows 10 update.
Printing a PDF Pattern is like printing other documents. First open the PDF pattern and afterwards choose File and Print. The printing dialogue box opens up, make sure to set the print scale at 100% and actual size. Do NOT check “scale to fit” nor fit to page. The labels in your dialog box may vary but those are the most common options. You print on one side only as you will be cutting your pattern pieces later.
Before printing the entire pattern, print the page in your pattern with the one inch/four centimetres test square. Print only this page first to check and measure that the one inch/four centimetres test square is correct. If it does not measure correctly check your print scaling options.
If you wish to print only one size of a pattern, check the detailed instructions on the pattern tutorial regarding to Print with layers option.
