ABSTRACT:
The files containing status information from remote systems (RS) of a network are transferred automatically to a local system (LS) controlling a printer thanks to this procedure. To do this, with the printer connected to the network, associated with each file transfer two synchronization files or "pipes" are used, the first (P.sub.1) in the direction local system to remote system and the second (P.sub.2) in the direction remote system to local system. Thus, an automaton for retrieving status reports is created for the purpose of printing them on the printer of the local system. These synchronization files principally provide the synchronization and communication between a scan and command process (SCP) of the remote system which is initiated on the local system and a file transfer process (FTP) which returns the status reports to be printed from the remote system to the local system.
