The parameters are arranged in ascending order of parameter name. Reader — The print data consists of the Unicode characters read from the stream up to the end-of-stream. The character pair carriage return-line feed CR-LF means “go to column 1 of the next line.
DocFlavor (Java Platform SE 7 )
Thus clients which want to stream platform encoded text data from the host platform to a Java Print Service instance must explicitly declare the charset and not rely on defaults. This convenience method will return the value of the specified parameter if one was specified in docflqvor mime type for this flavor. I have written code to run the printer programatically in Java. The media type, media subtype, and parameter names are converted to lowercase.
Identifies the attributes that are unsupported for a print request in the context of a particular DocFlavor. Sign up using Facebook. It can’t print the text file. Reader as the print data representation class. The service may be some form of network print service jqva is executing in a different environment.
For service formatted print data, the print data representation class is typically one of the following although other representation classes are permitted. A Doc object lets the DocPrintJob determine the doc flavor the client can supply. Developers working in the English locales should be particularly conscious of this, as their platform encoding corresponds to the default mime charset.
Also note that this is different than the behaviour of the Java runtime when interpreting a stream of bytes as text data. String as the print data representation class. String getRepresentationClassName Returns the name of this doc flavor object’s representation class.
The bytes are encoded in the character set specified by hava doc flavor’s MIME type. The printer calls methods in that interface to obtain the image to be printed. I have to set the value of docflavor to print the. URL provides predefined static constant DocFlavor objects. As far as I understand your Windows printer cannot print text files.
That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.
SerializableCloneable Direct Known Subclasses: The two are equal if the given object is not null, is an instance of DocFlavorhas a MIME type equivalent to this doc flavor object’s MIME type that is, the MIME types have the same media type, media subtype, and parametersand has the same representation class name as this doc flavor object. Thus, when spooling a file in local encoding to a Java Print Service it is important to correctly specify the encoding.
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. Quoting backslash characters inside parameter values are removed.
Thus the class name for byte is “[B”for char it is “[C”. However, developers who have print services that support these doc flavors are encouraged to refer to the predefined singleton instances created here.
DataFlavor does not guarantee that equivalent data flavors will have the same serialized representation.
That assumes the default encoding for the user’s locale. Plain text print data provided through a byte stream. Specifically, the following doc flavor is recommended to be supported: Printable object — Ddocflavor client supplies an object that implements interface Printable.
String toString Converts this DocFlavor to a string. String as the print data representation class. InputStream — The print data consists of the bytes read from the stream up to the end-of-stream.
Java Examples for javax.print.DocFlavor
To print such documents, let the client open docflavkr input stream on the URL or file and use an input stream data flavor. The printer calls methods in that interface to obtain the pages to be printed, one by one.
The doc flavor’s representation class is a conduit for the JPS DocPrintJob to obtain a sequence of characters or bytes from the client. Constructs a new doc flavor object from the given MIME type and representation class name. Use is subject to license terms. 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. Sep 17 ’09 at The media type, media subtype, and parameters are retained, but all comments and whitespace characters are discarded.
A DocPrintJob obtains its print data by means of interface Doc. For each page, the printer supplies a graphics context, and whatever the client draws in that graphics context gets printed.

I am using HP Deskjet F printer for this. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working docflacor examples.
