## Title
Margin adjustment

## Abstract

In one embodiment, a width of a print media is measured. A margin adjustment decision is made utilizing a margin instruction if the measured width is within an acceptable variance from a standard width of the media. The margin adjustment decision is applied to a plot of an image to be printed on the media.

## Background
BACKGROUND
A user of a printing device typically specifies a standard-sized media that is desired for printing in an application. For example, a user of a large format printer may choose from among several standard sized media rolls to print to a 600 mm media roll with a particular standard width. The user may make the choice of a media reasoning that in a particular application using 600 mm standard width media will result in the best appearance, the least media waste and/or no manual trimming.

DETAILED DESCRIPTION OF EMBODIMENTS
Due to manufacturing errors, a standard sized print media sometimes does not have an actual width that is the same as the listed width. For example, standard sized print media rolls used in large format printers typically have variability up to +−3 mm, as reflected by ISO width tolerances for print media with a width greater than 600 mm. Such variability between an actual width and a listed width can cause significant errors when a user or a printing application makes decisions that require accurate measurements. For example, a printing application may, based on input information regarding standard print media widths, make a decision to select a particular media width to avoid waste, to avoid manual trimming of a plot to achieve desired dimensions, to clip content to fit a particular print media size, or to put a print job on hold until a narrower or wider print media roll can be loaded. If the listed information regarding print media width is incorrect and such error is not detected, the user or printing application will make such decisions in error and the result will be poor quality, lost time, and/or wasted ink and print media. Embodiments described below were developed in an effort to provide a method and system to effectively manage a variation between a standard and an actual media width by making and applying a margin adjustment decision.

ENVIRONMENT: FIG. 1 depicts an example environment 10 in which various embodiments may be implemented. Environment 10 is shown to include a client 12, server 14, and a printer 16 interconnected via link 18.
Client 12 represents generally any computing device capable of receiving content from, and sending content to a server 14 and/or printer 16 via a link 18. Client 12 is also responsible for receiving and processing responses to requests for content. As used in this specification and the appended claims, “processing” includes executing instructions in memory to perform some transformation and/or computation on data in the computing device's memory. Processing may include displaying visual content such as text, images, and motion video on a monitor as well as broadcasting audio content via one or more speakers. Example client devices include laptop computers, desktop computers, smart phones, cell phones, personal digital assistants, net-books, digital media players, and the like.
Server 14 represents generally any computing device capable of serving content to, and receiving content from, a client 12 and/or a printer 16 via link 18. The term content refers to visual and audible information that can be presented to and received from a user of a client 12. Examples include images, audio, and video. Content can also include instructions designed to be processed by a client 12. Examples include HTML code and various scripts. As discussed with reference to FIG. 5 below, server 14 may be a print server operable to receive a print fulfillment request and/or content from a client 12 and in response cause a printer 16 to produce printed output.
Printer 16 represents generally any device operable to receive and process responses to requests to print content from client 12 and/or server 14, and to produce printed output.
Link 18 represents generally one or more of a cable, wireless, fiber optic, or remote connection via a telecommunication link, an infrared link, a radio frequency link, or any other connector or system that provides electronic communication. Link 18 may represent an intranet, the internet, or a combination of both. The paths followed by link 18 between client 12, server 14 and printer 16 as depicted in FIG. 1 represent the logical communication paths between these devices, not necessarily the physical paths between the devices.
COMPONENTS: FIG. 2 depicts an example of a margin selector 20. Margin selector 20 represents generally any combination of hardware and programming configured for use in making and applying a margin adjustment decision to a plot of an image to be printed. In the example of FIG. 2, margin selector 20 is shown to include a measurement engine 22, a decision engine 24 and an application engine 26.
Measurement engine 22 represents generally any combination of hardware and programming configured to measure a width of a print media. As used in this specification and the appended claims, a “print media” is an object that can be printed upon. “Print media” and “media” are used synonymously in this application. In an embodiment, measurement engine 22 includes a sensor, or utilizes a reading from a sensor external to measurement engine 22, to measure a width of the print media. In embodiments, the sensor can be an optical sensor, a laser sensor or an LED sensor. In an embodiment the sensor is positioned within a printer and configured to scan the print media and provide a reading at the time the media is loaded into a printer. In an embodiment the sensor is positioned within a printer and configured to scan the print media and provide a reading at printer startup or upon receipt of a print job. In an embodiment, the reading is made utilizing a device that is external to a printer, such as a handheld device, that includes a sensor.
Decision engine 24 represents generally any combination of hardware and programming configured to make a margin adjustment decision utilizing a margin instruction if the measured width is within an acceptable variance from a standard width of the media.
As used in this specification and the appended claims, a “standard width” is a declared or intended width for a print media absent production error or other errors. In an embodiment, the standard width may be obtained or determined in various ways, including via a user interface and via sensor reading. In an embodiment, the standard width may be received by utilizing a sensor to read a bar code or other marking that appears on the print media or supporting structure (e.g. a spindle that holds roll print media). In an embodiment, the standard width may be obtained or determined by utilizing a sensor to a read bar code or other marking that appears on packaging or written materials that accompany the print media. In an embodiment, the standard width may be received via user input at a user interface such as a keyboard, mouse or touchscreen.
As used in this specification and the appended claims, a measured width is within an “acceptable variance” from a standard width if the measured width deviates from the standard width and the deviation is of a degree that has been evaluated as tolerable. If the measured width is within an acceptable variance from a standard width printing can continue on the print media after application of a margin adjustment decision. In an example, the decision engine may be configured such that it recognizes a variability of +−3 mm as an acceptable variance for a print media roll with a standard width of 600 mm. In this example, a print media roll with a measured width between 597 mm to 603 mm is deemed as being within an acceptable variance from the standard width.
As used in this specification and the appended claims, a “margin” is a region that borders an image on a printed or displayed page. In an example, a plot can be designed such that the when printed an image that measures 600 mm in width will be bordered by a left margin of 6 mm and a right margin of 6 mm. In most cases the margin will be blank space, but other margins are possible, such as a pattern margin. In another example, a plot may be designed with a 0 mm margin, such that the image prints to an edge of the media. For example, a plot that is designed to print a 600 mm image on 600 mm width media is said to include left and right margins of 0 mm.
As used in this specification and the appended claims, a “margin instruction” is a directive as to how to configure a margin in the event a measured width of a media is within an acceptable variance from the standard width of the media. In an embodiment the margin instruction may be an instruction from a user and may be received via a user interface such as a keyboard, mouse or touch screen. In an embodiment, the margin instruction may be embedded in a plot of an image to be printed, and the margin instruction is read from the plot. As used in this specification and the appended claims, a “plot” is a representation of an image converted to programming language and/or numerical form so that it can stored and used in computing devices, servers, printers and other machines capable of performing calculations and manipulating data. As used in this specification and the appended claims, an “image” is a visual representation of an object, scene, person or abstraction (including text). The plot may include instructions as to how the image is to be printed. In embodiments, a plot may be expressed in a number of various languages and formats, including but not limited to HPGL/2 (Hewlett-Packard Graphics Language 2), PostScript, PDF (Portable Document Format), JPEG (Joint Photographic Experts Group standard), TIFF (Tagged Image File Format) and PCL3 (Printer Command Language 3). In an embodiment, the plot may have a margin instruction that is embedded using a PJL (Printer Job Language), the margin instruction to indicate to a printer how to manage the margin layout. In an embodiment the margin instruction may be a default instruction that is stored in, and read from, memory. In an example, the margin instruction may be an instruction to “center image”. In another example of a margin instruction is an instruction to “keep left margin” or “keep right margin”. In another example, a margin instruction may be an instruction to “do nothing” with respect to adjusting margins, i.e. make no margin adjustments, if the measured width is within an acceptable variance from the standard width.
As used in this specification and the appended claims, a “margin adjustment decision” is a decision as to how to configure a margin for a plot to be printed when a measured width of a media is within an acceptable variance of the media's standard width. The margin adjustment decision is made utilizing a margin instruction. In an example, a margin adjustment decision to modify both a first margin and a second margin on a print media may be made in response to a margin instruction to center an image. In another example, a margin adjustment decision to maintain a first margin and modify a second margin may be made in response to a margin instruction to keep one of a left margin or a right margin. In another example, a margin adjustment decision to make no margin adjustments may be made in response to a margin instruction that is received and which directs that no margin adjustments be made when the measured width of a media is within an acceptable variance from the media's standard width.
In an embodiment, if the measured width of a first media is not within an acceptable variance from the standard width of the first media, no margin adjustment decision is made and printing operations may be suspended until a second media that is equal to, or within an acceptable variance from, its standard width is made available.
Application engine 26 represents generally any combination of hardware and programming configured to apply the margin adjustment decision to a plot of an image to be printed on the media. In an embodiment, the margin adjustment decision may be applied to the plot by embedding the margin adjustment decision into the plot. In an embodiment, the margin adjustment decision may be embedded into the plot using a PJL that will indicate to the printer how to manage the margin layout. In an embodiment, the margin adjustment decision may be applied to a plot of an image to be printed on the media by communicating the decision to a printer separately from the plot, the printer being configured to accept the margin adjustment decision as superseding margin instructions set forth in the plot. In an embodiment, applying a margin adjustment decision to a plot results in the margin decision overwriting any default margin configurations that would have been effected but for such applying of the application decision.

As used in this specification and the appended claims, “printhead” includes a mechanism having a plurality of nozzles through which ink or other fluid is ejected. Examples of printheads are drop-on-demand inkjet printheads, thermo resistive printheads, piezo and resistive printheads. Some printheads may be part of a cartridge which also stores the fluid to be dispensed. Other printheads are standalone and are supplied with fluid by an off-axis ink supply.

OPERATION: FIGS. 6 and 7 are example flow diagrams of steps taken to implement the making and applying of a margin adjustment decision, in accordance with an embodiment. In discussing FIGS. 6 and 7, reference may be made to the diagrams of FIGS. 1-5 to provide contextual examples. Implementation, however, is not limited to those examples.
Starting with FIG. 6, a width of a print media is measured (block 72). Referring back to FIG. 2, the measurement engine 22 may be responsible for implementing block 72. In an embodiment, an optical sensor is included within a printer's media loading apparatus and is configured to scan and measure the print media at the time the media is loaded into a printer.
Continuing with the flow diagram of FIG. 6, a margin adjustment decision is made utilizing a margin instruction if the measured width is within an acceptable variance from a standard width of the media (block 74). Referring back to FIG. 2, the decision engine 24 may be responsible for implementing block 74. In an embodiment, the margin instruction may be embedded in a plot of an image to be printed, and the margin instruction is read from the plot. In an embodiment the margin instruction may be a default instruction that is stored in, and read from, memory. In an embodiment, a margin instruction may be an instruction to center an image. In an embodiment, a margin instruction may be an instruction to maintain one margin, to maintain a left margin, or to maintain a right margin.

Referring back to FIG. 2, the application engine 26 may be responsible for implementing block 76. In an embodiment, the margin adjustment decision may be applied to the plot by embedding the margin adjustment decision into the plot. In an embodiment, the margin adjustment decision may be applied to a plot of an image to be printed on the media by communicating the decision to a printer separately from the plot, the printer being configured to accept the margin adjustment decision as superseding margin instructions set forth in the plot. In an embodiment, applying a margin adjustment decision to a plot results in the margin decision overwriting any default margin configurations that would have been effected but for such applying of the application decision.
Moving on to FIG. 7, in a particular implementation, a width of a print media is measured (block 78). Referring back to FIG. 2, the measurement engine 22 may be responsible for implementing block 78. In an embodiment an optical sensor is included within a printer's media feeding apparatus and configured to scan and measure the print media at printer startup or upon receipt of a print job.
Continuing with the flow diagram of FIG. 7, a plot with an embedded margin instruction is received. In this example, the margin instruction directs that an image be centered when the measured width of the media to be printed upon is within an acceptable variance from the media's standard width (block 80). Referring back to FIG. 2, the decision engine 24 may be responsible for implementing block 80. In an embodiment, the margin instruction may be embedded in the plot using a PJL that will indicate to the printer how to manage the margin layout.
Continuing with the flow diagram of FIG. 7, if the measured width is within an acceptable variance from standard width of media, a margin adjustment decision is made utilizing the margin instruction to center the image. The margin adjustment decision is a decision to modify a first and a second margin to center the image on the media (block 82). Referring back to FIG. 2, the decision engine 24 may be responsible for implementing block 82. In an embodiment, the standard width is determined by utilizing a sensor to a read bar code or other marking that appears on packaging or written materials that accompany the print media.
Continuing with the flow diagram of FIG. 7, the margin adjustment decision is applied to a plot of an image to be printed on the media (block 84). Referring back to FIG. 2, the application engine 26 may be responsible for implementing block 84. In an embodiment, the margin adjustment decision may be embedded into the plot using a PJL that will indicate to the printer how to manage the margin layout.
Continuing with the flow diagram of FIG. 7, the plot is used to print the image on the media (block 86).

In an embodiment, the plot may be in HPGL/2, PostScript, PDF, JPEG, TIFF or PCL3 format, and provides the image to be printed and instructions for printing the image on the media. In an embodiment, raster image processing may take place after receipt of the plot and before printing.
EXAMPLES: The diagrams of FIGS. 8A, 8B, and 8C provide an example implementation of a method and system to make and apply a margin adjustment decision. Starting with FIG. 8A, a sensor 88 is utilized in measuring a width 92 of a print media 90 at 598 mm. It is determined that the print media 90 has a standard width 94 of 600 mm. In embodiments, the standard width 94 may be determined utilizing a sensor to read a marking on the media, by utilizing a sensor to read a marking on packaging or other materials that related to the media, or by user input via a user interface, or by other means.
Moving to FIG. 8B, a plot is received that includes instructions to print an image 88 with a width of 588 mm between a left margin 96 of 6 mm and a right margin 98 of 6 mm on a media with a standard size 94 of 600 mm. The plot also includes a margin instruction to center the image if it is found that the measured width 92 of the media 90 is within an acceptable variance of the standard width 94 of the media 90.
In this example, we assume a policy that that any measured width of a media that is within +−3 mm from the standard width is with an acceptable variance from the standard width. The −2 mm difference 100 between the measured width 92 and the standard width 94 is within the +−3 mm acceptable variance, therefore a margin decision utilizing a margin instruction can be made and printing of the image 88 to the media 90 can continue without changing media size or changing the width of the image 88.
FIG. 8C illustrates a printed media 102 that is the end result of the application of the margin adjustment decision to modify the left 96 (FIG. 8B) and right 98 (FIG. 8B) margins of the plot of the image 88 (FIG. 8B). After application of the margin decision, the plot includes a modified left margin 104 that has a width of 5.97 mm and a modified right margin 106 has a width of 5.97 mm.
