As will be discussed in greater detail, once transmitted from the printers 301, 302 and installed on the print client 200, the document acquisition drivers 3013, 3023 may be utilized to generate a print document communication that sends a print document in its native format to the target printer.
Also, as will be discussed in greater detail, the printer-side printing applications 3014, 3024 may generate a return communication to the print client 200 including a document acquisition driver 3013, 3023. In addition, after receiving the print document in native format, the printer-side pinning applications 3014, 3024 may also, among other things, implement native format drivers 3015, 3025 to convert the print document from its native format to a target printer format (e.g., printer control language) that is ready for print execution.
In this embodiment, the printer 301 utilizes a hardwired communication technology to communicate with the print client 200, while the printer 302 may utilize a wireless communication technology. Specifically, the printer 302 may utilize a printer transceiver 3026 to communicate wirelessly via various communication protocols (e.g., near-field communication, Wi-Fi, Bluetooth) with the print client 200.

In certain embodiments of the present invention, the website 600 and the OEM database 700 may be part of a cloud service, wherein the cloud, service may be accessed to provide a driver as described herein.
The arrangement and numbering of blocks depicted in FIG. 1 is not intended to imply an order of operations to the exclusion of other possibilities. Those of skill in the art will appreciate that the foregoing systems and methods are susceptible of various modifications and alterations. For example, in another embodiment, the client network 100 may not include the network database 400.
Turning now to FIG. 2, a flowchart of an exemplary method of utilizing a target printer to acquire a driver to process a print request according to one embodiment of the present invention is shown. The method might be implemented as a set of logic instructions stored in a machine- or computer-readable storage medium such as random access memory (RAM), read only memory (ROM), programmable ROM (PROM), firmware, flash memory, etc., in configurable logic such as programmable logic arrays (PLAs), field programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), in fixed-functionality logic hardware using circuit technology such as application specific integrated circuit (ASIC), complementary metal oxide semiconductor (CMOS) or transistor-transistor logic (TTL) technology, or any combination thereof. For example, computer program code to carry out operations shown in the method may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages.
In this embodiment, as user may utilize a print client, such as the print client 200 (FIG. 1), that is located within a network, such as the LAN network 100 (FIG. 1), to direct at print request to a target printer, such as the target printer 302 (FIG. 1). In this embodiment, the print client and the target printer may communicate wirelessly via Bluetooth protocol.
The method begins at processing block 2000. At processing block 2010, the user may initiate the print request through a print client GUI interface, such as the client-side printing application 203 (FIG. 1) discussed above. At processing block 2020, the print client OS may search for and generate a list of available printers. At processing block 2030, the prim client OS may present the user with the list of available printers, and provide a prompt to select the target printer.
After selection of a target printer, at processing block 2040, the print client OS may recognize that the driver for the target printer is not installed on the print client. At processing block 2050, responsive to this recognition, the print client OS may initiate a clientside printing application, such as the client-side priming application 203 (FIG. 1), discussed above. At processing block 2060, the client-side printing application may issue a request communication to the target printer to execute a print request, wherein the request communication may include relevant characteristics of the print client (e.g., OS type, CPU type) and the print document (e.g., print document format) to aid the target printer in completing the print request.
At processing block 2070, responsive to receiving the request communication, the target printer may initiate a printer-side printing application, such as the printer-side printing application 3013 (FIG. 1). At processing block 200, the printer-side printing application may generate a return communication including a document acquisition driver, such as the document acquisition driver 3024 (FIG. 1) discussed above. The return communication may also include a message to the user (e.g., indicating the file should be sent in native format). At processing block 2090, the print client receives the return communication, and the document acquisition driver is installed at the print client. At processing block 2100, the document acquisition driver generates and transmits a print document communication including the print document in native format to the target printer. At processing block 2110, the target printer receives the print document communication.
At processing block 2120, the printer-side printing application may utilize the relevant characteristics included in the print document communication, to search for, locate, and acquire a native format driver. As discussed above, the printer-side printing application may search for the native format driver at, among other places, a printer memory device, such as the printer memory device 3021 (FIG. 1) already discussed, a network database such as the network database 400 (FIG. 1) already discussed, on a website located on the Internet such as Internet 500 (FIG. 1 already discussed, or an OEM database, such as the OEM database 700 (FIG. 1) discussed above, among other places. In this embodiment, the printer-side printing application may locate the native format driver at the printer memory device.
If no native format driver is found, the printer-side printing application may transmit a message to the print client that the print request cannot be completed (at processing block 2130), and the process returns to processing block 2000.
At processing block 2140, upon locating and acquiring the native format driver, the target primer may utilize the native format driver to convert the print document from its native format to the target printer format. At processing block 2150, the target printer may process the print request and may print the document. At processing block 2130, the process may terminate.
It will be evident to persons having the benefit of this disclosure that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the embodiments described herein. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
For example, in various embodiments of the present invention, the return communication and the searching, locating, and acquiring of the native format driver may be initiated at different points in the process. In the example described above, the return communication including the document acquisition driver (i.e., processing block 2080) is generated before the printer-side printing application searches for, locates, and acquires the native format driver (i.e., processing block 2120). This does not necessarily have to be so. In other embodiments, the return communication including the document acquisition driver and the searching, locating, and acquiring of the native format driver may occur in different order. That is, the target printer may utilize the information received in a request communication (e.g., document format type) to search for, locate, and acquire a native format driver before transmitting the return communication including the document acquisition driver.
Also, in the example described above, the printer may send a document acquisition driver (i.e., processing block 2080), which may be installed at the print client (i.e., processing block 2090), and may transmit a print document communication including the print document in native format to the target printer (i.e., processing block 2100). This does not necessarily have to be so. In other embodiments, the print client may simply transmit the print document directly to the target printer (e.g., in a print message or an email message to the target printer), without the help of a document acquisition driver. The target printer may receive the print document in native, format, and may search for, locate, and acquire a native format driver to convert the print document from its native format to the target printer format for printing.
Those skilled in the art will appreciate from the foregoing description that the broad techniques of the embodiments of the present invention can be implemented in a variety of forms. Therefore, while the embodiments of this invention have been described in connection with particular examples thereof, the true scope of the embodiments of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification, and following claims.
In addition, in some of the drawings, signal conductor lines are represented with lines. Some may be thicker, to indicate more constituent signal paths, have a limber label, to indicate a number of constituent signal paths, and/or have arrows at one or more ends, to indicate primary information flow direction. This, however, should not be construed in a limiting manner. Rather, such added detail may be used in connection with one or more exemplary embodiments to facilitate easier understanding. Any represented signal lines, whether or not baying additional information, may actually include one or more signals that may travel in multiple directions and may be implemented with any suitable type of signal scheme, e.g., digital or analog lines implemented with differential pairs, optical fiber lines, and/or single-ended lines.
Example sizes/models/values/ranges may have been given, although embodiments of the present invention are not limited to the same. As manufacturing techniques (e.g., photolithography) mature over time, it is expected that devices of smaller sire could be manufactured. In addition, well known power/ground connections and other components may or may not be shown within the figures, for simplicity of illustration and discussion, and so as not to obscure certain aspects of the embodiments of the invention. Further, arrangements may be shown in block diagram form in order to avoid obscuring embodiments of the invention, and also in view of the fact that specifics with respect to implementation of such block diagram arrangements are highly dependent upon the platform within which the embodiment is to be implemented, i.e., such specifics should be well within purview of one skilled in the art. Where specific details are set forth in order to describe example embodiments of the invention, it should be apparent to one skilled in the art that embodiments of the invention can be practiced without, or with variation of, these specific details. The description is thus to be regarded as illustrative instead of limiting.
