Stamps can be printed either from the SendPro Online software or from the web version of SendPro Online. Stamps without a date can only be printed from the SendPro Online software. Stamps must be printed on compatible SendPro postage sheets, which are available in our online shop item numbers SL-SPM01 and SL-SPM11).
Each stamp sheet has a unique serial number and contains either 20 or 25 blank stamp stickers. Older sheets with 25 stamps (SL-SPM01) have serial numbers that start with "A", and newer sheets with 20 stamps (SL-SPM11) have serial numbers that start with a character other than "A". SendPro keeps track of how many stamps you print with each serial number, so you do not have to use the entire sheet at once.
The postage value printed is as-is and is not a USPS Forever Stamp. If USPS postal rates change, you can print a postage correction stamp which can be used with an already printed stamp to add additional postage.
