How to solve the issue of print size being too small (using 8*11 inch as an example)?

Your file is an 8*11 label, not a 4*6 format, which results in a lot of unused white space surrounding the label.

If the document includes large empty areas or extra information outside the label, you can trim the blank sections using cropping tools or software.

Solutions:

For APP：

1. Send the PDF file to be printed from your computer to your phone via WhatsApp or Email, then open the file using the FlashLabel Pro app.

•  For detailed steps, refer to: "How to send a PDF from your computer to your phone via WhatsApp or Email".

   Note: If the FlashLabel Pro app is not installed on your phone, follow “How to use printer on the Phone” to complete the installation first.
