Since EDMs can be exported as a PDF, printing them out is put on the table. It's an option that comes in handy when needed. However, do note that there are several important things to consider in order to achieve the intended output.
NOTE: This guide is generally for those instances where you want the template to print in a single page. However, there are still helpful points that can help you improve your design.
When creating an EDM for printing, you should be aware of the distinction between media on paper and on screen. Being aware of the space limitations of actual paper is important, for this purpose.
The best way to start an EDM template for printing is to determine that the template is for print first, digital second. If at all. Deciding to print an EDM on the fly is going make the process complicated.
Manage the length of your template by adding blocks that don't stretch out too much.
In general, having a generous amount of white space is good design philosophy. Find a good balance so that white spaces won't cause the template to exceed a single page upon printing.
One section that could greatly reduce the vertical size of the template is the header. Consider using one that isn't too tall but still retains the essence of the header's purpose in the template.
Another section of the template that can be removed entirely to make the print-out shorter are conditional blocks.
(don't add conditional blocks unless it's needed to be in print**)

As previously mentioned, white space adds breathing space that'll make your design look cleaner in general. However, if it gets in the way of printing the template in a single page, reduce top or bottom padding a bit to make the template shorter.
Turn the "more" toggle on to specify padding properties for top and bottom.
Readability is one of the core concerns when creating a template, whether for print or on screen. In printing a template in particular, font sizes should not be reduced drastically to the point that readers will have to squint to read anything.
Minimum font size can vary depending on the typeface used. Cleaner typefaces can still be legible in lower pt sizes. For the most part, consider not going below 8pt.
On the other hand, making text a lot bigger than they have to be will, of course, add to the height of the template. Unless it's a deliberate stylistic choice, avoid going overboard with huge texts in a template for print.
Exporting, tweaking, and printing
Most of the time, in order to confirm whether the EDM will fit on a single page or not, the template will have to go through more than one iteration.
After exporting, if the template goes over one page in the resulting PDF, simply go back to the builder and do more tweaking to achieved desired result.
Extra blank page
PDF exports can sometimes manifest a nuance that can cause a minor issue.
If your exported PDF has this, carefully check if the second page is actually blank. If so, just delete the extra page. Most PDF readers have this function.
In Preview (MacOS), for example, you can just click on the page in thumbnail view and press 'Delete'.
Make sure that the blank page IS a blank page before deleting.
To skip all of these guidelines and extra steps - if there's no practical reason to cram everything in one page - you might want to look into the option of printing the template regardless of the output number of pages.
