Abstract:
Bidirectional communications between a host computer and a printer connected to the host, either locally or by way of a network, are used to provide a user of the host with access to a substantially real-time, visual and functional replica of the operator panel of the printer. The user may view the replica to access all data available through the printer operator panel. Using a mouse or other input device, the user of the host computer can also effectively actuate any pushbuttons or other operator panel control devices depicted as part of the replica.
Abstract:
A networked system having a host computer and multiple printers with bi-directional communications capabilities is provided in which the setup (configuration) of one printer can be easily communicated to another printer, using NPAP messages. The host computer can be used by a Network Administrator to "read" the setup or configuration information inside each of the printers connected to the network that have the required NPAP bi-directional communications capability. This setup information, once communicated to the host computer, can be stored in a long-term memory, such as a hard disk drive, for future reference. The setup information can also be communicated to one or more printers connected to the network, and such printers can be configured by the setup information in which that information is used either as their initial setup information, or as a modified setup. The Network Administrator can use a single command that specifies precisely which printers are to receive that setup information, and all specified printers will automatically be reconfigured with the new setup.

Abstract:
An improved printing system is provided having at least one host computer and a printer in which the printer acquires print job accounting information and communicates it to the host computer via NPAP messages. A host computer downloads print job data to the printer through a communications port on the printer (i.e., either a parallel port, serial port, or network port), and as the printer prints the print job that it received from the host computer, the printer temporarily stores job accounting information. At the end of the print job, the printer communicates that job accounting information back to armed host computers via a bi-directional communications port, including typical information such as: the job identifier number, job processing time, number of sheets of paper from each paper source, number of impressions from each paper source (either one-sided or two-sided impressions), the port identifier, the network user name, the name of the print job (as specified), and the printer's serial number. Since the data is being accumulated at the printer, rather than at the host computer, there is no estimating by a host-resident program to acquire these statistics, and no data base merging (from several host computers) is required to categorize all of the data for one particular printer. Furthermore, the print jobs need not pass through a network queue in order to be detected and accounted for.
