In a method for the error-monitored transmission of data via interfaces of a multi-step communication system, the data is transmitted from a transmitter station to a data-receiving station via at least two relay stations which are connected therebetween and receive and further transmit the data parallel to each other. The data is retransmitted if the transmission has been insufficient due to a request from the receiver end and/or due to the lack of a confirmation from the receiver end. In order to increase performance while reducing power consumption of the system, the request or confirmation is generated only by the receiver station and is sent back to the transmitter station. The relay stations consequently do not generate any confirmations or requests.

What is disclosed is a novel system and method for automatically retrieving and configuring the print device to a set of device specific system settings tailored for user selected media attributes. In one embodiment, an operator selects media attributes desired for a particular print job on a print device which then automatically queries a database over a network for a set of device specific system settings tailored to the selected media attributes. The database system determines the existence of at least one record stored in the database and provides that matching record data back to the print device. The matching record data is received and displayed on a user interface for review by an operator. The operator accepts/modifies the displayed system settings. The print device then automatically configures the device to the accepted device specific system settings.
