A postage metering system includes a plurality of meter printers operatively connected as part of a metering network and operating as client meter printers on the meter printer network. At least one postal security device (PSD) is coupled to at least one of the client meter printers (local client meter printer). The PSD includes unique identification the ability to store postal value and generate digital signatures. The client meter printers function as a postage metering network wherein a client meter printer other than the local client meter printer (remote client meter printer) requests evidence of postage payment from the PSD for concluding a postage metering transaction. The local client meter printer functions as a meter server and the remote client meter printer functions as a meter client on th e postage metering network. The remote client meter printer initiates a postag e metering transaction in the PSD by sending a request for evidence of postage payment to the local client meter printer. The local client meter printer sends the request for the evidence of postage payment to the PSD, receives transaction information from the PSD and sends the evidence of payment to the remote client meter printer for subsequent printing.
