what does portedDocFlavors returns for you? Maybe UTF-8 is unsupported? Edit: “text/plain; charset=utf-8” seems to be unsupported. Try. This page provides Java code examples for vor. The examples are extracted from open source Java projects from GitHub. Class _STREAM provides predefined static constant DocFlavor objects for example doc flavors using a byte stream (tream) as.

RenderableImage” A Java Print Service instance is allowed to support docflxvor other doc flavors or none in addition to the above mandatory ones, at the implementation’s choice. Post as a guest Name. I have written code to run the printer programatically in Java. Sign up using Email and Password.
Java Print Service API User Guide: 3 – Specifying Document Types
Thus, two doc flavors with MIME types that are not identical but that are equivalent that have the same canonical form may be considered equal. This is not appropriate as part of a service matching constraint. Also note that this is different than the behaviour of the Java runtime when interpreting a stream of bytes as text data. Not working, I made change you have suggested,but still no printing activity.
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. Mime types may include parameters which are usually optional. A Doc object lets the DocPrintJob determine the doc flavor the client can supply.
This convenience method will return the value of the specified parameter if one was specified in the mime type for this flavor. The media type, media subtype, and parameter names are converted to lowercase. The value returned from method is valid only for the VM which returns it, for use in a DocFlavor.
InputStream” Renderable image objects. String getRepresentationClassName Returns the name of this doc flavor object’s representation class. Thus the class name for byte is “[B”for char it is “[C”. The character pair carriage return-line feed CR-LF means “go to column 1 of the next line. As far as I understand your Windows printer cannot print text files. Thus, when spooling a file in local encoding to a Java Print Service it is important to correctly specify the encoding.
A CharSet which corresponds to this and is suitable for use in a mime-type for a DocFlavor can be obtained from DocFlavor. URL provides predefined static constant DocFlavor objects. IANA Charset Registration Procedures except where historical names are returned for compatibility with previous versions of the Java platform.
The bytes are encoded in the character set specified by the doc flavor’s MIME type. To print such documents, let the client open an input stream on the URL or file and use an input stream data flavor.
This name is internally converted to the canonical lower case format before performing the match. For service formatted print data, the print data representation class is typically one of the following although other javq classes are permitted.
DataFlavor does not guarantee that equivalent data flavors will have the same serialized representation. In a distributed environment there is no gurantee that two VM’s share the same default encoding.
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.
This means you dodflavor not use a URL print data flavor to print a document at a restricted URL that the client can see but the printer cannot see. 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. The printer calls methods docflavof that interface to obtain the image to be printed. Following is my code. The service may be some form of network print service which is executing in a different environment.
By this coincidence that particular case may work without specifying the encoding of platform data. Use is subject to license terms. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.
Plain text print data provided through a byte stream. Dkcflavor instance of the Java virtual machine has a default character encoding determined during virtual-machine startup and typically depends upon the locale and charset being used by the underlying operating system. It can’t print the text file.

Maybe UTF-8 is unsupported? The implementation of class java. See character encodings for more information on the character encodings supported on the Java platform.
