Secure circuitry detects a latency between when an interrupt occurred and when the interrupt was released in correspondence with handling of the interrupt. The secure circuitry detects an interval between consecutive occurrences of the interrupt. In response to either or both of the latency exceeding a latency limit and the interval exceeding an interval limit, the secure circuitry performs an action.

A method of printing a print job includes storing print job data on a non-volatile memory device that includes a connector for connection to a port of a printer.

Copy-protected documents are generated for intended recipients by integrating a document, each recipient name on a recipient list, and a security template into distinct copy-protected documents.

A docking station for a wireless mouse includes an output for communicating with a computer and a mouse detector for detecting when the mouse is docked in the docking station. The docking station is configured to transmit a signal to the computer to automatically deactivate the computer when the mouse is docked in the docking station.

A processor executes a document rendering application for an open document. When the open document is unedited and a predetermined portion of the processor is available, the document is rendered to an output buffer. The rendering is suspended when a predetermined interrupt is received and is resumed after the predetermined interrupt has been serviced. When the document has been edited, any rendered portion of the document is removed from the output buffer and the document is reset as being unedited.

Apparatus, systems and methods for print previewing are provided. One method includes providing a print preview that reflects a consumable availability status and optionally proceeding with a print job.

Consumable availability with print preview

A printer comprising one or more consumables and a network connection searches a network connected via the network connection for pricing for the one or more consumables. A user is notified when pricing below a user-specified amount is found.

Printer-based consumables price searching

A printer comprises at least one print control that can be operated by a user. In response to operation of the print control, the printer generates and transmits a request from the printer to a general purpose computer that has data stored in it. The request contains information to cause the computer to execute a print operation. The printer prints the data received from the computer.

An electronic device includes a scanning device for converting one or more configuration symbols on a printed medium into scan data. The scanning device is capable of scanning a configuration sheet and creating the scan data, including the one or more configuration symbols. The electronic device further includes a configuration device that receives the scan data and is capable of extracting the one or more configuration symbols to create one or more corresponding address-independent configuration values. The configuration device is further capable of configuring the electronic device with the one or more address-independent configuration values.

A method for printing includes estimating ink usage for printing with a first color scheme and a second color scheme, and selecting between the first color scheme and the second color scheme for printing according to the estimating of the ink usage. An apparatus includes a first sensor to measure a level of a first ink, a second sensor to measure a level of a second ink, and a processor coupled to the first sensor and the second sensor and configured to estimate usage of the first ink and the second ink using a first color scheme and a second color scheme and configured to select the first color scheme or the second color scheme for use in printing according to the estimate of the usage of the first ink and the second ink.

An electronic device includes a scanning device for converting indicia and markings on a printed medium into scan data and a configuration device that receives the scan data. The scanning device is capable of scanning a user-fillable configuration sheet marked by a user of the electronic device and creating the scan data, with the scan data including one or more configuration indicia. The configuration device is capable of decoding the one or more configuration indicia to create one or more corresponding configuration values and configuring the electronic device with the one or more configuration values.

A system includes an operating mode in which the system detects requests to print nearly-blank pages and suppresses their printing. The detection and suppression may occur in a computer or other host device, in a printer, or in an intermediate device. A nearly-blank page may be identified in any of multiple ways. The mode may optionally be switched off so that nearly-blank pages are printed. The mode may optionally apply to only the last page in a print job.

A system to determine the length of time, known as the latency time, that is required to wait between transmitting and receiving data for a half-duplex electromagnetic transceiver having a transmitter and receiver wherein the receiver is electromagnetically coupled to the transmitter. The determination of the latency time is accomplished by the use of a control circuit that operates to turn the transmitter to an on state. The control circuit then monitors the receiver to determine when the receiver also goes to an on state due to the electromagnetic coupling. The control circuit subsequently turns off the transmitter and the length of time for the receiver to recover to an off state is measured. This length of time is the latency time and is used in subsequent transmission of data.
