• Multi-page documents often include content created using a diversity of desktop applications including word processing, drawing, graphing and spreadsheet tools. Because of operating system and middleware complexity, many users are unable to integrate diverse content into a single presentation document. In many cases, a single presentation document combines content created by different users, all of whom may have particular application skills, but none of whom may have content integration skills. Because of this users often resort to manual collation.
• the present invention provides, in a first aspect, a printer for printing a collated multi-page document when presented with a plurality of manually collated pages, the printer including: (a) a code sensor which senses machine-readable codes on the manually collated pages; (b) a control unit which uses the machine-readable codes to identify and retrieve previously stored electronic versions of the pages; and (c) a print engine which prints the retrieved pages.
• the printer includes a binder for binding together the printed pages, and a scanner for copying pages which do not have machine-readable codes on them and which produces electronic versions of the pages.
• the printer includes a storage medium which stores the electronic versions of the scanned pages, and a hand-held code sensor which senses machine-readable codes on the manually collated pages wherein the machine-readable codes on the manually collated pages are represented: (a) optically; or (b) electronically; or
• the code sensor senses machine-readable codes on both sides of the manually collated pages
• the control unit also controls communications between the printer and one or more peripheral devices.
• electronic versions of the manually collated pages which are to be printed are retrieved from at least one of the group including:
• the printer includes an input device with which a user of the printer controls the format of the printed and collated multi-page document, wherein the input device includes a touch sensitive display, and wherein the print engine also prints machine-readable codes onto a page, and wherein the machine-readable codes are not visible to human vision.
• the printer inserts blank pages in the printed document to duplicate blank pages contained within the manually collated pages.
• instructions from a handheld code sensor are received and interpreted, and a collated multi-page document is produced.
• the printer includes an interface which transmits instructions for printing a collated multi- page document to a second printer, wherein the instructions are transmitted over a computer network or over a telephone network.
• the printer includes a storage medium which stores an electronic version of pages which have been printed.
• the invention provides a method of printing a collated multi-page document when presented with a plurality of manually collated pages, the method including the following steps: (a) sensing machine-readable codes on the manually collated pages using a code sensor;
• the invention provides a method including the step of binding together the printed pages, and further including the steps of using a scanner for copying pages which do not have machine-readable codes on them and producing electronic versions of those pages.
• the step of printing the retrieved pages includes printing machine-readable codes on those pages, and wherein the machine-readable codes are invisible.
• the code sensor senses machine-readable codes on both sides of the manually collated pages.
• the method includes the step of using an input device to control the format of the printed and collated multi-page document, and wherein the printing step includes the sub-step of transmitting the retrieved pages to a remote printer.

• Figure 5 is a partial block diagram of a printer controller with facsimile modem according to an embodiment of the invention.
• Figure 6 is a flow diagram of a printing and copying control process.
• a page can be printed with one or more machine-readable codes which identify an electronic version of the page stored in a computer system. This can allow the page to be used as a token for obtaining a pristine digital copy of the page, described further in our earlier application PCT/AU00/1279, obviating any need to physically scan and print (i.e. "photocopy") the page. It can also allow the page to be used in conjunction with a hand-held code-sensing device to capture user input in relation to the page, such as handwriting and hyperlink activations described further in our earlier application PCT/AU00/00561.
• the machine-readable codes are preferably unobtrusive and ideally invisible, e.g. printed using an ink which is machine-readable but invisible to the unaided human eye, such as an infrared-absorptive ink.
• Documents which may be selected and printed in this way are typically documents which have been previously printed via the printer, and in the process stored on the printer's internal hard disk. To optimize printing speed, the documents are typically stored, in a rasterized or partially-rasterized format. A user may have the option to "print" a document to the printer's hard disk, i.e. to make it available for walk-up printing without actually printing it.
• a walk-up printer may utilize storage on a local-area or wide-area network rather than having its own internal storage, and a group of such printers may have access to a shared document repository.
• a walk-up printer may also simply record links to original documents rather than making copies.
• a printer may include a binding mechanism for binding the pages of a document into a single whole.
• Various binding mechanisms suitable for inclusion in a high-speed work-group printer are described further in our co-filed application PCT/AUOO/01456. Since a document must typically be sent to a printer as a single document to produce a bound copy, document integration is normally a prerequisite for binding. This presents a barrier to many users.
• the present invention concerns a printer which can produce one or more bound documents when presented with a manually-collated bundle of pages.
• the printer contains a code sensor for sensing machine- readable codes on the pages, allowing it to identify and produce printed copies of the pages from electronic versions of the pages.
• the printer optionally contains a scanner for copying pages which are not coded.
• the copying process may be used to produce double-sided output from single-sided input. Blank pages can be interspersed with the input to force the inclusion of blank pages.
• the printer of the preferred embodiment has two input trays, one for source pages 1012, the other for sheets 1014 of an input medium such as paper.
• the paper path includes an input transport mechanism 1022, one or more code sensors 1024, one or more print engines 1026, an output transport mechanism 1028, and a binding mechanism 1030, 1032.
• a printer controller 1040 controls the printing process.
• the printer has a single output tray in which it accumulates both decoded source pages 1012 and printed and bound documents 1020.
• the printer may have separate output trays for source pages and documents.
• source page sensing and printing both utilize the same paper transport mechanism.
• the printer may contain separate page sensing and printing paper paths and associated transport mechanisms.
• the preferred binding mechanism consists of a page-height adhesive applicator 1030, and a page-height stamper 1032.
• the adhesive applicator applies a strip of adhesive adjacent to the spine of a page just before the page enters the output bin.
• the stamper 1032 presses the pages in the output bin together, causing pages with adhesive strips to adhere to each other.
• Adhesive may be applied to either the front or the back of each page of a document. When it is applied to the front, it is not applied to the first page. When it is applied to the back, it is not applied to the last page.
• the stamper is typically operated after the last page of the document is printed, although if adhesive is applied to the front of each (face-down) page, then the stamper may be used after each page is printed or periodically during the printing of a document.
• Alternative binding mechanisms include corner or page-height stapling and clamping.
• the preferred code sensor 1024 described further in our earlier application PCT/AUOO/00561, consists of a light source, projection and image capture optics, and an image sensor. Codes are represented by optical patterns which are printed or otherwise applied to a surface, for example as described further in our earlier application PCT/AUOO/00561.
• the printer controller 1040 captures images of the page surface via the image sensor, decodes the optical patterns found in the images, and thereby obtains one or more codes which directly or indirectly identify the source page and/or a document of which the source page is part. Codes may alternatively be represented electronically, magnetically, topographically, or chemically, with correspondingly adapted code sensors.
• the input transport mechanism 1022 picks up an input sheet 1014
• the print engines 1026 print the page content onto one or both sides of the sheet
• the output transport mechanism 1028 deposits the sheet in the output tray.
• the adhesive applicator 1030 applies adhesive
• the input transport mechanism 102*2 picks up a source page 1012
• the processor senses codes from one or both sides of the source page via the code sensors 1024
• the output transport mechanism 1028 deposits the source page in the output tray.
• Copying consists of a code sensing phase followed by a printing phase.
• the code sensors are a fixed part of the apparatus.
• the code sensor may be embodied in a hand-held device, such as a suitably enabled pen or stylus, as described further in our earlier application PCT/AU00/00565, so that the user specifies how the printed document is collated by manually sensing a set of pages, in which case the printer need not necessarily include the code sensor 1024 in the paper path.
• the printer is ideally enabled for printing codes which it can subsequently sense. This is not a requirement, however, and the printer may simply be used in conjunction with source pages printed by another printer.
• the printer may also be enabled, described further in our earlier application PCT/AUOO/00561, for receiving, interpreting and/or relaying transmissions from a hand-held code sensing device, such as a suitably enabled pen or stylus, as described further in our earlier application PCT/AU00/00565.
• a hand-held code sensing device such as a suitably enabled pen or stylus
• the printer has a user interface which minimally provides a "copy" button.
• the user inter-face may also include a color touch-sensitive display which allows a user to browse a list of documents accessible to the printer, and select a particular document for printing.
• the copy button may also be provided in virtual form on the display.
• the printer transports each source page in the input tray past the code sensors and records the corresponding page identity information.
• the printer uses the page identity information to retrieve electronic versions of the pages, and uses these electronic versions to print "copies" of the source pages, bound into a single document.
• the printer consults a locally- or network-stored index of documents and/or pages to identify and retrieve the electronic versions of the pages.
• the user interface may allow the user to select or specify typical photocopying and printing options, including the number of copies, whether documents are bound, single-sided versus double-sided printing, scaling of page content, and media selection, including different media sizes.
• the printer controller 1040 handles communication with host computers, manages the user interface, and controls the printing process. It consists of an integrated controller chip 1041 and a number of separate components.
• the controller includes a processor 1042 which runs control software loaded into a DRAM 1044 from a flash memory 1046. The processor may also download control software from a host computer.
• the printer controller communicates with host computers via a network interface 1046.
• the network interface may provide direct connection to a host computer, such as a serial, parallel (IEEE 1284), Universal Serial Bus (USB) or IEEE 1394 connection, or connection onto a local-area network, such as an Ethernet, or connection onto a wide-area net- work, such as the Internet.
• the controller may include multiple such network interfaces.
• the printer controller may include a disk controller 1056 for controlling a hard disk 1058 internal to the printer.
• the printer controller may use the hard disk for storing queued print jobs, i.e. documents, rasterized or partially-rasterized pages, and an index of documents and pages. It may also utilize storage provided by computers accessible via its network interface for some or all of these purposes.
• the printer controller includes a display controller 1060 for controlling a color display 1062, and a touch sensor 1066 overlaid on the display for capturing us.er interactions with the displayed user interface.

• At least one illumination LED 1070 is typically associated with each image sensor.
• the printer controller also controls the illumination LEDs 1070 via the parallel interface 1064, although they may be more closely coupled with the relevant image sensor interface 1060 to allow them to be efficiently strobed in synchrony with image capture.
• the printer typically includes one or two printheads 1052, depending on whether it has a duplex printing capability or not, although it may include additional printheads to achieve higher-speed printing or to support more complex ink sets.
• the printer controller includes a high-speed serial interface 1048 for communicating with a pair of print engine/controllers 1050, each of which controls a printhead 1052.
