I create printable educational products for teachers and homeschoolers. I need to be able to make some printable PDFs that have cards set to a specific dimension, say 3" x 3". When I create PDFs in InDesign and print them, the printer tends to shrink the PDF down. This happens even when I set the Page Scaling to None. But regardless of what my printer does, I would like to be able to create PDFs that print at actual size for anyone who purchases my products. How can this be done? Can I change the settings when I create the PDF? Do I need to includes special instructions with my products? Thanks so much for your help.
Print scaling is controlled by the PDF viewing application at print time. You have no control over what other users' settings might be.
Thank you, Peter. So would you recommend that I put some print instructions in each document to help the customer try to print at actual size? If so, do you know what those instructions should be?
You can specify the printing process in the PDF for Acrobat and Reader, open the PDF in Acrobat > file properties (right mouse click on the page) and in the extended tab (the most right tab) you can set printing not to scale for that PDF as default setting.
