The Epson driver for Windows will be the one that controls the paper size.

For most users, you'll see the A5 paper size by default.

You can double check it by heading to Hardware and Sound > Devices and Printers

Then double click on the Epson printer icon.

You should see the A5 option there.

  • Before printing a prescription inside SeriousMD, load the half bond paper (5.5x8.5) OR A5 paper to your printer.
  • Move the paper guide so it fits the paper exactly

  • Pick A5 as the paper size in the popup (Example below is for Chrome)
  • Print it out! Sign the prescription and you are done!


If you do not see the A5 option or in a rare printer-specific issue that causes your A5 option to get cut-off, please do the following steps.

  • In the Devices and Printers area, double click on your printer icon
  • Once inside, you will see this. Click the Paper link shown in the image below.
  • For the document size, click on User-Defined
  • Add a paper size name
  • Set paper width to 5.5 
  • Set paper height to 8.5
  • Set unit to inches
  • Click on Save
  • Print a prescription and select the paper size  you just created.
  • Print it out and it should look like this.
