Nested classes inside class DocFlavor declare predefined static constant DocFlavor objects for these example doc flavors; class DocFlavor’s constructor can be used to create an arbitrary doc flavor.
Determines the doc flavor in which this doc object will supply its piece of print data.
Plain text print data provided through a byte stream. Locates factories for print services that can be used with a print job to output a stream of data in the format specified by outputMimeType.
Renderable image xocflavor — The client supplies an object that implements interface RenderableImage. The preferred form is the official IANA docflaovr name for an encoding. String toString Converts this DocFlavor to a string. The service may be some form of network print service which is executing in a different environment.
Each parameter value is enclosed in quotes. I have to set the value of docflavor to print the. When the representation class is a URL, the print service itself accesses and downloads the document directly from its URL address, without involving the client.
DocFlavor (Java Platform SE 7 )
DataFlavor does not guarantee that equivalent data flavors will have the same serialized representation. It can’t print the text file. The character pair carriage return-line feed CR-LF means “go to column 1 of the next line. InputStream — The print data consists of the bytes read from the stream up to the end-of-stream.
In a distributed environment there is no gurantee that two VM’s share the same default encoding. The printer calls methods in that interface to obtain the image to be printed. Locates print services capable of printing the specified DocFlavor.
Email Required, but never shown. Reader as the print data representation class. Pageable object — The client supplies an object that implements interface Pageable. InputStream” Renderable image objects.
Additionally a few historical names supported by earlier versions of the Java platform may be recognized.
By this coincidence that docflvaor case may work without specifying the encoding of platform data. Thus clients which want to stream platform nava text data from the host platform to a Java Print Service instance must explicitly declare the charset and not rely on defaults.
A CharSet which corresponds to this and is suitable for use in a mime-type for a DocFlavor can be obtained from DocFlavor. This MIME type is just a placeholder; what’s important is the print data representation class.
Java Examples for javax.print.DocFlavor
This convenience method will return the value of the specified parameter if one was specified in the mime type for this flavor. The doc flavor’s representation class denotes an interface whose methods the DocPrintJob invokes to determine the content to be printed — such as a renderable image interface or a Java printable interface.
True if this doc flavor object equals objfalse otherwise. Furthermore, every Java Print Service instance must fulfill these requirements for processing plain text print data: The media type, media subtype, and parameters are retained, but all comments and whitespace characters are discarded. Client Formatted Print Data There are two broad categories of print data, client formatted print data and service formatted print data.
As far as I understand your Windows printer cannot print text files. DocFlavor does, and can be used in services which need this.
The implementation of class java.
Java example source code file (PrintAutoSenseData.java)
If the printer doesn’t support the client’s preferred doc flavor, the client can at least print plain text, or the client can convert its data to a renderable image and print the image. Class DocFlavor’s serialized representation also contains the fully-qualified class name of the representation class a String objectrather than the representation class itself a Class object. Following is my code. For example the client may have a JPEG encoded image, a URL for HTML code, or a disk file containing plain text in some encoding, possibly obtained from an external source, and requires a way to describe the data format to the print service.
Also see the documentation redistribution policy. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. However, developers who have print services that support these doc flavors are encouraged to refer to the predefined singleton instances created here. Determines the printing attribute values a client can specify in the given category when setting up a job for this print service.
Interface Doc provides two utility operations, getReaderForText and getStreamForBytesto help a Doc object’s client extract client formatted print data. MIME type string based on the canonical form.
This name is internally converted to the canonical lower case format before performing the match.
It only prints the jpeg format file. For client formatted print data, the print data representation class is typically one of the following although other representation classes are permitted: Determines whether a client can specify the given printing attribute value when setting up a job for this Print Service. Printable object — The client supplies an object that implements interface Printable.
A Doc object lets the DocPrintJob determine the doc flavor the client can supply. Sign up or log in Sign up using Google. Mime types may include parameters which are usually optional.
Specifically, the following doc flavor is recommended to be supported: A Doc object also lets the DocPrintJob obtain an instance of the doc flavor’s representation class, from which the DocPrintJob then obtains the actual print data.
