摘要： Apparatus, systems, and methods consistent with disclosed embodiments provide for managing the printing of documents using recycled media. In some embodiments, a printer comprises at least one input tray capable of holding print media; at least one image sensor capable of detecting recycled print media; and a print engine capable of placing marks on documents. The print media received from the input tray is routed to an output tray without marking by the print engine, if the image sensor detects recycled print media in the print media feed path during the processing of a non-recycled print; otherwise the print media is routed to a print engine on the printer.

摘要： Apparatus, systems, and methods consistent with disclosed embodiments provide for the secure printing of documents. A first security data is associated with a document, which is printed to one of several secure trays coupled to a printer, if a second security level derived from the first security data is not lower than the first security level currently associated with the secure output tray. The first security data is matched with second security data obtained from an input device coupled to the printer. Access to the secure tray is granted if the second security data matches a subset of the first security data. In some embodiments, secure output trays on the printer may be dynamically assigned to different security levels corresponding to the security levels of documents printed to the secure output trays.

摘要： An improved document authentication method in which critical content, such as signatures, is preserved at a high-resolution in the authentication data carried on the self-authenticating document. When generating authentication data, signatures are compressed without down-sampling to preserve their resolution and quality. The compressed signature data (a bit string) is embedded in an image segment on the document. For example, each bit of the bit string is stored in the low bits of one or more image pixels. A hash code is calculated from the bit string and stored in a barcode printed on the document. To authenticate a scanned-back document, the bit string is recovered from the image segment. A hash code is calculated from the recovered bit string and compared to the hash code extracted from the barcode. The signatures re-generated from the recovered bit string are compared to the signatures in the scanned document.
摘要翻译：一种改进的文档认证方法，其中在自我认证文档上承载的认证数据中以高分辨率保留关键内容（例如签名）。当生成认证数据时，签名被压缩而不进行下采样，以保持其分辨率和质量。压缩的签名数据（位串）被嵌入在文档的图像段中。例如，位串的每个位被存储在一个或多个图像像素的低位中。哈希码是从比特串中计算的，并存储在打印在文档上的条形码中。要验证扫描的文档，将从图像片段中恢复位串。从恢复的位串中计算哈希码，并与从条形码提取的散列码进行比较。从恢复的位串重新生成的签名与扫描的文档中的签名进行比较。

摘要： Systems and methods are provided for reducing data size of at least one bitmap image using a look-up table, wherein the look-up table stores information correlating a plurality of compression ratios to a set of compression parameters and wherein the bitmap image comprises a plurality of image components, each image component associated with a distinct color plane. The plurality of color planes may be ranked using a dominance rank, wherein the dominance rank for a color plane is based on image component data associated with the color plane. At least one compression ratio may be associated with each color plane based on the dominance rank associated with the color plane. At least one image component may be compressed according to the compression ratio associated with the color plane corresponding to the image component using compression parameters obtained from the look-up table. The compression ratio may be iteratively adjusted, until the total data size of the plurality of image components is below a data size threshold.

摘要： A print job canceling method for a printer is described and is especially useful in a printer with relatively small buffer memory. When a print job is cancelled by the user using the printer's control panel, this method allows the printer controller to receive additional print jobs while the current job is being cancelled, without having to notify the host to stop sending the current print job. The printer controller reduces the memory allocated to the job being cancelled. The printer controller continues to accept data for the current job from the host, but does not print the received data. The data is subsequently flushed from the memory. The printer controller also assigns a lower priority to the print job being cancelled. Meanwhile, the remaining memory can be used to receive and print additional print jobs.
摘要翻译：描述了打印机的打印作业取消方法，并且在具有相对较小的缓冲存储器的打印机中特别有用。当用户使用打印机的控制面板取消打印作业时，此方法允许打印机控制器在当前作业被取消时接收其他打印作业，而不必通知主机停止发送当前打印作业。打印机控制器减少分配给正在取消的作业的内存。打印机控制器继续接受来自主机的当前作业的数据，但不打印接收到的数据。数据随后从存储器中刷新。打印机控制器还为要取消的打印作业分配较低的优先级。同时，剩余的存储器可用于接收和打印其他打印作业。

摘要： Systems and methods are provided for dynamically converting first color data to second color data using a look-up table, wherein the first color data is a subset of a first color space, and the second color data is a subset of a second color space. In some embodiments, at least one first color value is input in the first color data. At least one look-up table entry may be calculated for the at least one first color value in the first color data, if the look-up table entry has not been previously calculated. The at least one calculated look-up table entry may be stored. At least one value in the second color data, which corresponds to the at least one first color value, can be computed based on the at least one first color value and the stored value of the at least one look-up table entry.

摘要： A document authenticating method is disclosed by which numerous small-sized two-dimensional barcode stamps are generated and placed in a distributed manner on a printed document. The small-sized barcode stamps collectively encode the content of the document to be used for document authentication. In one example, the stamp size is about ¼ by ¼ inches or less and the tile size for the stamps is 4 by 4 pixels at a resolution of 400 dpi. The document is segmented into segments each containing a paragraph or a line of text. For each segment, a set of barcode stamps encoding the authentication data for the segment is placed in the vicinity of the segment. They may be placed in the empty space in the last line of each paragraph, in the empty space between adjacent paragraphs, or at the beginning or end of each line.

摘要： A method for printing only text objects within a PDF document is described. PDF data is transmitted from a host computer to a printer, along with job information that specifies a text-only mode. If printer controller detects that the text-only mode is specified, it interprets only the text objects within the PDF data. As a result, only text objects are printed on the recording medium, and the graphics and image objects are not printed. The interpretation step preserves position, font, size, and style (e.g. bold, italic, underline) of the text objects. Representation may be generated and printed on the recording medium to indicate the presence of graphics or image objects in the original PDF document.

摘要： A color barcode can record much more amount of information than black white barcode. However, the problem of the color barcode is that it is easy to lose integrity or authenticity in printing and copy generation. This invention provides an apparatus and a method to keep the integrity or authenticity of the color barcode. Such is accomplished by the color reference portion of the color barcode including reference color tiles filled with colors which are used in a data portion of the color barcode and an apparatus and a method for producing, reproducing and reading such color barcode.
