Printing to a Larger Scale on A4/Letter Paper

I am often asked how to print my models out to a larger scale using A4/Letter sized paper, (in O Gauge for instance), without resorting to a print shop or using the “Poster” feature in PDF Viewer applications.

Here is how I do it using Adobe Acrobat Reader:

  1. Open the PDF file of the model using Acrobat Reader.
  2. Select “Take a Snapshot” which can be found under the “Edit” drop down menu.
  3. Select a portion of the PDF by holding down the left button on your  mouse and selecting.
  4. Right click your mouse over the selected area and select “Print” this will open the print dialogue box.
  5. Set the “Custom Scale” box to the scale you wish to enlarge the selection, for O Gauge 175%.
  6. Click away from the “Custom Scale” box and select another scale option, it does not matter what. Then, click back onto “Custom Scale“. The preview for the new scale will show what will be printed.
  7. Check that the enlarged selection fits on an A4/Letter sized page. Try moving from Portrait to Landscape if it does not, or go back to Step 3 and select a smaller portion of the page.
  8. Once happy, click “Print“.
  9. Repeat this for all the components on each page.

This should allow you to print out components at the scale needed without having to include joints where a component crosses two sheets if using the “Poster” option, or will allow you to put the joint in a better place of your choosing if a joint is unavoidable due to the size  of the component.
