Disclosed herein is a method for automatically detecting page description languages supported by image production devices, as well as corresponding apparatus and computer-readable medium.
In conventional image production device networks, when a system is submitting a job to an image production device, such as a printer, the system must know which PDLs (Page Description Language) the image production device supports before generating the PDL for the device. In conventional image production devices, the PDL must be defined in advance of a print job and must be set for every image production device in which the system will interact. Device changes, such as adding PDLs, require modifications to settings to take advantage of the new PDL which adds time and complexity to the process.
A method and apparatus for automatically detecting page description languages supported by image production devices is disclosed. The method may include receiving a print job for printing, determining which page description languages are supported by each image production device in the image production device network, determining if the print job's page description language is supported by one or more image production devices in the image production device network. If the print job's page description language is supported, the print job is printed at one of the one or more image production devices using the print jobs page description language. If the print job's page description language is not supported, the print job is converted to a page description language supported by one of the one or more image production devices, and printed at the one of the one or more image production devices using the supported page description language.
Aspects of the embodiments disclosed herein relate to a method for automatically detecting page description languages supported by image production devices, as well as corresponding apparatus and computer-readable medium.
The disclosed embodiments may include a method for automatically detecting page description languages supported by image production devices. The method may include receiving a print job for printing, determining which page description languages are supported by each image production device in the image production device network, determining if the print job's page description language is supported by one or more image production devices in the image production device network. If the print job's page description language is supported, the print job is printed at one of the one or more image production devices using the print jobs page description language. If the print job's page description language is not supported, the print job is converted to a page description language supported by one of the one or more image production devices, and printed at the one of the one or more image production devices using the supported page description language.
The disclosed embodiments may further include an image production device management server that automatically detects page description languages supported by image production devices in an image production device network, that may include a communication interface, and a page description language management unit that receives a print job for printing through the communication interface, determines which page description languages are supported by each image production device in the image production device network, determines if the print job's page description language is supported by one or more image production devices in the image production device network, wherein if the print job's page description language is supported by one or more image production devices in the image production device network, the page description language management unit prints the print job at one of the one or more image production devices using the print jobs page description language, wherein if the print job's page description language is not supported by one or more image production devices in the image production device network, the page description language management unit converts the print job to a page description language supported by one of the one or more image production devices, and prints the print job at the one of the one or more image production devices using the supported page description language.
The disclosed embodiments may include a non-transient computer-readable medium storing instructions for controlling a computing device for automatically detecting page description languages supported by image production devices. The instructions may include receiving a print job for printing, determining which page description languages are supported by each image production device in the image production device network, determining if the print job's page description language is supported by one or more image production devices in the image production device network. If the print job's page description language is supported, the print job is printed at one of the one or more image production devices using the print jobs page description language. If the print job's page description language is not supported, the print job is converted to a page description language supported by one of the one or more image production devices, and printed at the one of the one or more image production devices using the supported page description language.
The disclosed embodiments may concern automatically detecting page description languages supported by image production devices. In particular, the disclosed embodiments may provide for an instance where the user submits an image production device job to an image production device management server which may detect the Page Description Language (PDL) that the device supports and take the appropriate action based on the document submitted by a user for processing. If the document is in a format that the image production device can accept directly, the image production device management server may send the document directly to the image production device and may not be converted to a PDL. If the file type cannot be accepted by the image production device it may be converted into the appropriate PDL before being delivered to the image production device. Updates to the accepted device PDLs may be detected automatically and become available.
The image production device management server may query each printer and retrieve the information from the printer to determine which PDLs the printer supports. The image production device management server may retrieve the description and version of the document to determine what is the best fit PDL to use. Once the description and version has been determined, the image production device management server or other device or application in contact with the image production device management server application, may use the information to determine how to process the image production device job before sending it to the image production device. As many image production devices support native document types like PDF, XPS, or TIFF, the image production device will determine if the document being printed is in one of these formats and send the document directly to the printer saving the time to convert it to PS or PCL.
The first process is to analyze the information returned from the printer in industry standard public MIBs to determine if the printer supports PS, PCL 5 or 6 and what native file formats are supported. The below workflow will be used to determine this information
