Products affected: SendPro® Online


When printing stamps, the stamp images are not properly aligned with the stamp labels on the stamp sheet.


The web browser's print settings need to be adjusted.


Solution 1: Make sure that you are using the correct stamp sheet

Older sheets with 25 stamps (SL-SPM01) have serial numbers that start with "A". These older stamp sheets are no longer sold for SendPro Online but can still be used if you have them. Newer sheets with 20 stamps (SL-SPM11) have serial numbers that start with a character other than "A". SendPro Online automatically adjusts the format based on the serial number you enter. The number of stamps on the sheet preview in SendPro Online should match the number of stickers on your sheet.

Solution 2: If using the SendPro Online software, try using SendPro in your web browser

If you are printing stamp sheets, try using SendPro Online in your web browser instead of using the SendPro Online software.

If the issue is not resolved, or if you are already printing stamp sheets from a browser, try solution 2.
