Buffered Printing?
Howdy all!
I have an application that I would like to print a HTML report from. I cannot guarantee that my application will be arned before closing so I would like to print the opening and closing statements of the HTML document first and print everything else within the <BODY> tags.
Can anyone recommend what output class I should be using?
Thank you for any assistance!
Rob
:)
something like this may do the trick.. i'm not sure if it's what you are looking for...
PrintStream headStream = new PrintStream (new FileOutputStream (new File("webpage.html")));
to print to it:
headStream.println(input);
input is a string in this case...

Msi rg54gs2 print server incompatibility
noticed the common issue with rg54gs2's print server throughout the forum..
i've got a hp dsc 1410 usb printer (which is not in the compat. list from msi).
i get it to print smaller documents via the server, but with larger files (photos i.e.) it starts, but suddenly halts while printing..
tried both direct and buffered print, disabled firewalls/encryption, checked signal etc...
got a p4 2.6ghz, 512mb with xp sp2 and an integrated 54mbit wlan.
can anyone relate to this problem or confirm rg54gs2's incompatibility with printers not in msi's list.
/silasyou'd probably get a better answer by contacting MSI support: http://support.msi.com.tw

Printing JTable after turning off double buffering causing repaint problems
I've followed all the instructions to speed up a print job in java by turning off double buffering temporarily by using the following call before calling paint() on the component...
RepaintManager.currentManager(printTable).setDoubleBufferingEnabled(false);
... and then turning it back on afterwards...
RepaintManager.currentManager(printTable).setDoubleBufferingEnabled(true);
but the problem is that if it is a long print job, then the rest of the application (including other JTables) isn't repainting properly at all. I have the printing going on in a separate thread since I don't think it's acceptable UI practices to force the user to wait until a print job finishes before they can proceed with using their application. I've tried controlling the double buffering at the JPanel level as well, but it always affects the entire application until the print spooling is complete.
Does anyone have any suggestions to solve this annoying SWING printing problem?
Thanks,
- TonyWhen you post code, make sure and put it between code
tags, so it looks good:
public static void main(String[] args) {
System.out.println("Doesn't this look great?");
public int print(Graphics g, PageFormat pf, int pageIndex) {
System.out.println( "Calling print(g,pf,pageIndex) method" );
int response = NO_SUCH_PAGE;
Graphics2D g2 = (Graphics2D) g;
// for faster printing, turn off double buffering
disableDoubleBuffering(componentToBePrinted);
Dimension d = componentToBePrinted.getSize(); //get size of document
double panelWidth = d.width; //width in pixels
double panelHeight = d.height; //height in pixels
double pageHeight = pf.getImageableHeight(); //height of printer page
double pageWidth = pf.getImageableWidth(); //width of printer page
double scale = pageWidth / panelWidth;
int totalNumPages = (int) Math.ceil(scale * panelHeight / pageHeight);
// make sure not print empty pages
if (pageIndex >= totalNumPages) {
response = NO_SUCH_PAGE;
} else {
// shift Graphic to line up with beginning of print-imageable region
g2.translate(pf.getImageableX(), pf.getImageableY());
// shift Graphic to line up with beginning of next page to print
g2.translate(0f, -pageIndex * pageHeight);
// scale the page so the width fits...
g2.scale(scale, scale);
componentToBePrinted.paint(g2); //repaint the page for printing
enableDoubleBuffering(componentToBePrinted);
response = Printable.PAGE_EXISTS;
return response;

Printing double-buffered component
I have a component that is double-buffered (must be) and when I print it, the quality of that component is pour. Quality of other components is good. So I'm guessing that image that I'm using for buffering is in the different resolution than the graphics that is used for printing, so g.drawImage() has to scale image which causses bad quality. I have seen posts about this problem but I haven't found a solution. Is there a way to fix this?
* The speed and quality of printing suffers dramatically if
* any of the containers have double buffering turned on.
* So this turns if off globally.
* @see enableDoubleBuffering
* @param c processed component
public static void disableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(false);
* Re-enables double buffering globally.
* @param c processed component
public static void enableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(true);

Need double buffering enabled if I print a JTable
Hi @ all
I have printed a very large JTable. The Problem is if I disable double
buffering the horizontal lines move after some pages.
If I enable double buffering the printout looks very bad(as all know).
But the horizontal lines are OK!
You can produce this failure with the print tutorial(and a large table).
Has someone an idea how I can fix my bug ?
many thanks for helpingmay be you have to disable double buffering generaly to all the element envolved in the printing component, try this:
private void setDoubleBuffering(Component c, boolean isEnabled) {
RepaintManager manager = RepaintManager.currentManager(c);
manager.setDoubleBufferingEnabled(isEnabled);

Hi All,
<br/>
<br/>We are now facing some problems on our smartform printing programs, sometimes some of the smartform programs look getting stuck, from SM50, the processing time is endless, and from the detailed tracing log, there are repeated messages like below for every ONE MINUTE:
<br/>I WARNING: MtxLock 0x70000000636197c rrol0046 owner=33 deadlock ?
<br/>
<br/>I've searched the forum and also did google and SAP notes but can not get useful information match with my error, so could anyone please help to analyse what exact cause of this problem? Any suggestions is highly appreciated.
<br/>
<br/>The smartform program itself is simple and correct, just has one header and several items and uses normal SSF_FUNCTION_MODULE_NAME and CALL FNAME to do the print work, in most of time it works correct, but sometimes it just has problem and then the deadlock error occurred. I guess maybe it's because user tried to print too fast than the capability of the printer and then user canceled the job, then in some situations, the upcoming printing jobs get blocked and then get stuck, but it's just a guess, i've no proof to identify it.
<br/>
<br/>Here I attached the full trace log, hope someone could give me a idea, thank you very much!

<br/>
<br/>Thanks very much for your fast reply. Yes, the smartforms are custom-built. Besides the deadlock error, there still has some errors in SP01 says "Could not pass request to host spool system". But it previews wonderfully in SP01. The detailed SP01 error log is like below:

What do you mean parallel processing on table level? The smartforms extract data from different SAP tables and then transfer to smartform interface, then they can added in form pages. Do you think this results parallel processing towards tables?
<br/>
Thank you and hope to hear more from you.

Happy new year,
before the holidays my attention was drawn to an issue that supposedly the Postscript produced by the JVM is too big and hence too slow. Here are my findings.
The issue
Text printing via CUPS to native Postscript printers can be slow. Printing a terms and conditions page (17000 characters/page) takes three and a half minutes to print on a Dell 2330 dn laser printer (96 MB,Max speed 33 ppm). The file is about 8 MB in size. To contrast that, rendering the text to a buffered image with 300 DPI and printing the result produces 7 MB of output which prints in 30 seconds on the same printer. More measures for different printers and documents can be found at the end of this post. The issues is registered as "JDK-4627340 : RFE: A way to improve text printing performance for postscript devices" (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4627340) and the proposed workaround is to use printer fonts.
Side remark regarding the workaround
There is a regression that prevents the workaround from working (bug 9008662 at Sun (not yet visible), bug 8023990 at OpenJDK (https://bugs.openjdk.java.net/browse/JDK-8023990). Without knowing what other bad side effects this might have, the issue can be resolved by setting the property "sun.awt.fontconfig". On my system I set it to the location of a "fontconfig.properties" of a JVM that does not have the bug (e.g. /home/alex/openjdk_7_b147_jun_11/openjdk/build/linux-i586/bin/java -Dsun.awt.fontconfig="/etc/java-6-openjdk/fontconfig.properties" Print2DtoStream). I also successfully tested the workaround on an Oracle JVM 1.7.0_03-b04.
Back to the main topic
How the JVM draws text if it can't use a standard printer font
Text is drawn with postscript path drawning commands such as "moveto", "lineto" or "curveto". As an example consider the word "ll" which looks something like this:
%N->short for "newpath"
N
%paint first "l"
%M->short for "moveto"
0.76875 11.06 M
%L->short for "lineto"
0.76875 2.468 L
1.823 2.468 L
1.823 11.06 L
0.76875 11.06 L
%p->short for "closepath"
P
%paint second "l"
3.649 11.06 M
3.649 2.468 L
4.703 2.468 L
4.703 11.06 L
3.649 11.06 L
P
The same text could be printed with a printer font using the command "(ll) show" which is much more compact but is available in Java only for the Postscript standard fonts and it isn't working at all right now as explained above.
Is it the file size?
My first thought was that the file size was the source of of slowness and so I wrote a small processor that would detect glyphs, normalize*1 them and place them in a dictionary. Recurring references to the same glyph were replaced by a dictionary reference (This is incidentally the fix proposed by the original author of RFE 4627340). This shrunk the file to about 11% of the original size but the processing time surprisingly doubled.
*1: With "normalizing" I mean applying a translation transform so that the smallest coordinates in the contours of a glyph are exactly 0. In addition I experimented with performing a normalizing scale transform so that all coordinates lie between 0 and 1 so that identical glyphs are detected at arbitrary positions and at different font sizes.
That led to the question to why there is such a big difference in performance between a Type 1 font dictionary and a self constructed dictionary since both contain basically the same drawing instructions. The difference is apparently that fonts are cached and user drawings are not unless explicitly told.
The Postscript "ucache" instruction
Postscript level 2 introduces the "ucache" instruction which seems to be defined for precisely this kind of problem. From the documentation:
"Some PostScript programs define paths that are repeated many times. To optimize the interpretation of such paths, the PostScript language provides a facility called the user path cache. This cache, analogous to the font cache, retains the results from previously interpreted user path definitions. When the PostScript interpreter encounters a user path that is already in the cache, it substitutes the cached results instead of reinterpreting the path definition. "
After adding "ucache" instructions to my filter the speed improved by factor 10.
To illustrate the said the "ll" text from above looked as follows after the transformation:
%definition of the glyph "l" named "p0"
/p0
ucache
0.000 0.000 1.054 8.592 setbbox
0.000 8.592 moveto
0.000 0.000 lineto
1.054 0.000 lineto
1.054 8.592 lineto
0.000 8.592 lineto
closepath
} cvlit def
G
N
0.769 2.468 translate
%draw "l" at 0.769 2.468
p0 ufill
-0.769 -2.468 translate
3.649 2.468 translate
%draw "l" at 3.649 2.468
p0 ufill
-3.649 -2.468 translate
For ucached shapes there is a special compact representation so that the same can be written as follows:
/p0
0.000 0.000 1.054 8.592
0.000 8.592
0.000 0.000
1.054 0.000
1.054 8.592
0.000 8.592
} cvlit def
G
N
0.769 2.468 translate
p0 ufill
-0.769 -2.468 translate
3.649 2.468 translate
p0 ufill
-3.649 -2.468 translate
Interestingly the speed improvement remained the same on a Chinese report that had hardly any character reuse. Upon this observation I changed the filter to not use a dictionary but so simply instruct the interpreter to cache each glyph definition and the performance remained nearly the same.
The initial "ll" text from above looks as follows after this transformation:
N
%paint first "l" cached
0.76875 2.468 1.823 11.06
0.76875 11.06
0.76875 2.468
1.823 2.468
1.823 11.06
0.76875 11.06
} ufill
%paint second "l" cached
3.649 2.468 4.703 11.06
3.649 11.06
3.649 2.468
4.703 2.468
4.703 11.06
3.649 11.06
} ufill
Note that I didn't normalize the shapes.
Why does this improve the performance so vastly if the shape is drawn only once? For a while I thought perhaps that the interpreter would consider two paths which differ only by a translation as being the same but rereading the documentation and looking at the Chinese example in which nearly all characters are unique, disproves this. The relevant part of the documentation reads:
"Caching is based on the value of a user path object. That is, two user paths are considered the same for caching purposes if all of their corresponding elements are equal, even if the objects themselves are not.
A user path placed in the cache need not be explicitly retained in virtual memory. An equivalent user path appearing literally later in the program can take advantage of the cached information. Of course, if it is known that a given user path will be used many times, defining it explicitly in VM avoids creating it multiple times.
User path caching, like font caching, is effective across translations of the user coordinate system, but not across other transformations, such as scaling or rotation. In other words, multiple instances of a given user path painted at different places on the page will take advantage of the user path cache when the current transformation matrix has been altered only by translate. If the CTM has been altered by scale or rotate , the instances will be treated as if they were described by different user paths."
An explanation that would fit the findings
The rasterizer renders the page multiple time (perhaps in order to save memory and produce horizontal strips). On the first rendering the cache is filled and reused on the subsequent renderings thereby improving performance even if all cached items are used only once.
Based upon this theory I hoped that the strip height would grow if I added more memory to the printer but this was not the case on the two printers for which I had memory to test with. Even substantial changes to the available memory (e.g. going from 32 MB to 96 MB) had no impact whatsoever on the performance.
Summary
The issue is not related to the file size as the original requester suspected but very likely due to the uncached rendering. Caching of glyphs can be achieved by using the "ucache" instruction or perhaps by placing the glyphs in font dictionaries and using the "show" operator.
Although reported in 2003, time is apparently not healing this quick enough since printers in the 10,000$ class like the Sharp MX2310U still take a full minute to print 10 pages and a desktop printer may be blocked for over an hour for the same document.
We will now try to use the CUPS filter and leave the printers configured as Postscript printers. If there is interest I can post the single file source of a CUPS filter that performs the inline conversion described. Apart from libl it requires no additional libraries and written using flex it is reasonably lightweight and fast.
I would appreciate any opinion on whether or not the proposed workaround for bug 8023990 (https://bugs.openjdk.java.net/browse/JDK-8023990), namely having the system property "sun.awt.fontconfig" pointing to a working fontconfig.properties of a previously installed and working 1.6 version file, is safe.
Measures (Appendix)
"Terms and Conditions" report
Testing a single page "Terms and Conditions" report in "Arial" 8pt (I am aware that "Helvetica" is width compatible and nearly looks the same but in this particular case the line height was also relevant and as explained above, printer fonts are currently not working). The page contains 17000 characters of which some parts are bold and some italic. This is a real world example and to make things worse the requirement is to print the text on the backside of every page on a certain class of reports. I am aware that this is a bit extreme but I also felt that I couldn't dismiss it as being unreasonable.

Will putting the boilerplate in the trailer section allow me to still have it appearing on the back page of the main report? This is where it needs to be as far as the printed report goes - it is duplexed.

Hello,
I have rendered my HTML on a JEditorPane with Editable set to false. The pages are displayed fine on the screen. However, when I try to print I have a problem. If I print in Portrait, everything prints just fine (only everything doesn't fit on the page). However, if I switch to Landscape (which should be an easy switch--pf.setOrientation(PageFormat.LANDSCAPE)), only the background of my tables prints on the page. Any ideas on this?
public void printReport() {
JFrame frame = new JFrame("Test");
JPanel allPages = new JPanel();
allPages.setLayout(new GridLayout(0,1));
for (int i=0; i<pages.size(); i++) {
((ReportPageHTML)pages.elementAt(i)).setPreferredSize(new Dimension(725,554));
((ReportPageHTML)pages.elementAt(i)).setMinimumSize(new Dimension(725,554));
allPages.add((ReportPageHTML)pages.elementAt(i));
((ReportPageHTML)pages.elementAt(i)).addPageNumber(i+1,pages.size());
((ReportPageHTML)pages.elementAt(i)).setText();
} //for
JScrollPane scrollPane = new JScrollPane(allPages);
frame.getContentPane().add(scrollPane);
scrollPane.setPreferredSize(new Dimension(300,100));
frame.setSize(600,400);
frame.setVisible(true);
frame.setState(JFrame.ICONIFIED);
PrinterJob printJob = PrinterJob.getPrinterJob();
PageFormat pf = printJob.defaultPage();
pf.setOrientation(PageFormat.LANDSCAPE);
double smallMargin = .4 * 72;
Paper paper = pf.getPaper();
paper.setImageableArea(smallMargin,smallMargin,(paper.getWidth() - (2*smallMargin)),(paper.getHeight()-(2*smallMargin)));
pf.setPaper(paper);
Book book = new Book();
for (int i = 0; i < pages.size(); i++) {
book.append((Printable)pages.elementAt(i),pf);
printJob.setPageable(book);
if(printJob.printDialog()) {
try {
printJob.print();
} catch (Exception e) {System.out.println("Print Exception " + e); }
frame.dispose();
}//printReport()
Hi!
Your code looks a bit to difficult i think...
I think it would be much easier, if your writing a class, wich Prints out the whole JEditorPane.
- create a new class thats implements Printable
- int the constructor you give the class your JEditorPane and save it in the class
MyEdPanePrint(JEditorPane ep) {
this.ep = ep;
- write the
public int print(Graphics g, PageFormat pf, int page)with:
-set the Pane undouble-buffered
-set the size (fixed size, or depending on pageformat pf);
-set it visible
-scale it, if you wanna change the resolution of the paper
-transform your GraphicsContextDevice
-print your JEditorPane
this is the standard way of printing as i would say.
It's easier and better to understand than your to print..
kind regards -
Print HTML File Without Showing on Screen
Hi Everyone
Is there a way to print a file (in particular, an html file) from a java app without actually displaying the file on the screen.
ie. print from command line.
I am creating an html file from within java app and would like to print it in one step.
Any help would be greatly appreciated.
Thanks
KellyHi,
Heres some code from an app I wrote that prints out text. I've stripped out little sensitive bits.
// Procedure to perform when print button is pressed
void printButton_actionPerformed(ActionEvent e){
int x, y, pageNo = 1, maxPageHeight, textHeight = 0;
Date today = new Date();
String tempLine = new String("");
String tempString = new String();
Graphics pg;
// Create date and time formats
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd/MM/yy");
SimpleDateFormat timeFormatter = new SimpleDateFormat("HH:mm:ss");
// Create date and time strings
currentDate = dateFormatter.format(today);
currentTime = timeFormatter.format(today);
// Turn off double buffering
RepaintManager.currentManager(this).setDoubleBufferingEnabled(false);
// Get a print job
PrintJob printjob = getToolkit().getPrintJob(this, "<printjob name>", null);
if (printjob != null) {
maxPageHeight = printjob.getPageDimension().height-(rowHeight*2);
pg = printjob.getGraphics();
if (pg != null) {
pg.setColor(Color.black);
pg.setFont(new Font("Courier", 0, 10));
// Print header
textHeight = topOfPage;
pg.drawString("Report Date " + currentDate +
" Time " + currentTime + " Page " + pageNo,
30, textHeight);
textHeight += rowHeight;
pg.drawString("File: " + dataFile , 30, textHeight);
// Print errors
textHeight += rowHeight*2;
pg.drawString("Errors", 30, textHeight);
textHeight += rowHeight;
pg.drawString("------", 30, textHeight);
textHeight += rowHeight;
pg.drawString("col1 col2 col3 Value Reason",
30, textHeight);
textHeight += rowHeight;
pg.drawString("------------ ---- -------------------- ------------ --------------------",
30, textHeight);
if(errorData != null){
for(x = 0; x < errorData.length; x++){
textHeight += rowHeight;
if(textHeight > maxPageHeight){
pg = nextPage(pg, printjob, ++pageNo);
textHeight = topOfPage + rowHeight*2;
tempLine = "";
for(y=0; y<columnLengths.length; y++){
tempString = errorData[x][y] != null ?
roundLength(errorData[x][y].toString(), columnLengths[y])
: roundLength(" ", columnLengths[y]);
tempLine += tempString + " ";
pg.drawString(tempLine, 30, textHeight);
pg.dispose(); // flush page
printjob.end();
}Hope that helps.

}Hi all,
Alright I managed to scale it to print the whole JFrame. But another problem surfaces. When I select draft quality printing, it doesn't print the whole JFrame. Other printing qualities (standard, high) do print the whole JFrame. I am really puzzled. Anyone has any clue?
And I have an unrelated question to this topic. How do I set a JTextField so that when I click on it the first time, it highlights its content? Have to work around with the mouselistener?
Thank you. -
Hi all,
I have a problem with printing JTable.
My application has a submit button,JTable and Print Button.
As I click on the Submit button, the data is retrieved from the Database(MS Access) and displayed on the JTable.
Now when I click on the Print button, the printer properties dialog box is displayed. But when I click on the print button in the dialog box, nothing is printed on the paper.
I checked the printers and faxes in the control panel, It showed Java printing under the Document name and Printing under the Status. It is displayed for sometime and then disappeared after some time. But nothing is printed on the paper(not even the blank paper).
I tried a lot but couldn't understand the problem.

i am getting different output on different printers as well. I have classes defined as Printeable that draw forms, each form has 75 questions and they are all done using graphics2D some printer prints all the pages perfectly some other with different margin and on a laser printer i get only one box.
If it helps someone, for testing, i printed to file (.prn) and read the ouput through Red Titan it's free
it showed me one box out of 76
just the first one ????
possible solution that would help for margin
http://java.sun.com/developer/JDCTechTips/2004/tt0611.html
i used book and send printeable class and appended them into the book class
i am dying to solve this problem and wondering if there is better way for testing and how to make all pages
compatible for all printers. I want my program to send all forms to printer same format same size
is there any suggestion?? what am i doing wrong?
by the way
bk.append((Printable)componentsToBePrinted[i],pf);
componentsToBePrinted[] is an array of classes that implements Printeable and they all draw the forms correctly and sends to the printer. It is working mostly but i needed to work on alll printers no exceptions
I appreciate any help and i will issue all my duke starts im new to posting in the forum but i will give all my points for this tip
PLEASE HELPI want my program to send all forms to printer same format same size is there any suggestion??Produce a PDF... effectively delegating printing there-of to someone else. Problem solvered.
Your PDF options are (AFAIK) FOP or itext.

Help with code to print HTML in Java 5
Hi,
The following code works and runs successfully..
However, the printing in Java 1.4.2_03 is better than Java 5 (latest version).
i.e in particular the characters are not monospaced compared with compiling with Java 1.4.2_03. e.g si so ss squashed together.
This issue does not seem to occur when running the same code in Java 1.4.2_03. (I haven't tried other 1.4.2 java versions).
Any help would be appreciated. We really need this working under Java 5 or bust.

/* DocumentRenderer prints objects of type Document. Text attributes, including
fonts, color, and small icons, will be rendered to a printed page.
DocumentRenderer computes line breaks, paginates, and performs other
formatting.
An HTMLDocument is printed by sending it as an argument to the
print(HTMLDocument) method. A PlainDocument is printed the same way. Other
types of documents must be sent in a JEditorPane as an argument to the
print(JEditorPane) method. Printing Documents in this way will automatically
display a print dialog.
As objects which implement the Printable Interface, instances of the
DocumentRenderer class can also be used as the argument in the setPrintable
method of the PrinterJob class. Instead of using the print() methods
detailed above, a programmer may gain access to the formatting capabilities
of this class without using its print dialog by creating an instance of
DocumentRenderer and setting the document to be printed with the
setDocument() or setJEditorPane(). The Document may then be printed by
setting the instance of DocumentRenderer in any PrinterJob.
protected int currentPage = -1; //Used to keep track of when
//the page to print changes.
protected JEditorPane jeditorPane; //Container to hold the
//Document. This object will
//be used to lay out the
//Document for printing.

//end.
protected double pageStartY = 0; //Location of the current page
//start.

//on a page will be scaled.
/* The DocumentRenderer class uses pFormat and pJob in its methods. Note
that pFormat is not the variable name used by the print method of the
DocumentRenderer. Although it would always be expected to reference the
pFormat object, the print method gets its PageFormat as an argument.

public void pageDialog() {

/* The print method implements the Printable interface. Although Printables
may be called to render a page more than once, each page is painted in
order. We may, therefore, keep track of changes in the page being rendered
by setting the currentPage variable to equal the pageIndex, and then
comparing these variables on subsequent calls to this method. When the two
variables match, it means that the page is being rendered for the second or
third time. When the currentPage differs from the pageIndex, a new page is
being requested.
The highlights of the process used print a page are as follows:
I. The Graphics object is cast to a Graphics2D object to allow for
scaling.
II. The JEditorPane is laid out using the width of a printable page.
This will handle line breaks. If the JEditorPane cannot be sized at
the width of the graphics clip, scaling will be allowed.
III. The root view of the JEditorPane is obtained. By examining this root
view and all of its children, printView will be able to determine
the location of each printable element of the document.
IV. If the scaleWidthToFit option is chosen, a scaling ratio is
determined, and the graphics2D object is scaled.
V. The Graphics2D object is clipped to the size of the printable page.
VI. currentPage is checked to see if this is a new page to render. If so,
pageStartY and pageEndY are reset.
VII. To match the coordinates of the printable clip of graphics2D and the
allocation rectangle which will be used to lay out the views,
graphics2D is translated to begin at the printable X and Y
coordinates of the graphics clip.
VIII. An allocation Rectangle is created to represent the layout of the
Views.
The Printable Interface always prints the area indexed by reference
to the Graphics object. For instance, with a standard 8.5 x 11 inch
page with 1 inch margins the rectangle X = 72, Y = 72, Width = 468,
and Height = 648, the area 72, 72, 468, 648 will be painted regardless
of which page is actually being printed.
To align the allocation Rectangle with the graphics2D object two
things are done. The first step is to translate the X and Y
coordinates of the graphics2D object to begin at the X and Y
coordinates of the printable clip, see step VII. Next, when printing
other than the first page, the allocation rectangle must start laying
out in coordinates represented by negative numbers. After page one,
the beginning of the allocation is started at minus the page end of
the prior page. This moves the part which has already been rendered to
before the printable clip of the graphics2D object.
X. The printView method is called to paint the page. Its return value
will indicate if a page has been rendered.
Although public, print should not ordinarily be called by programs other
than PrinterJob.

</html>I have finally cracked it!!!!!!!!!!!!!!!!
The issue is definitely with Java Sun. "Uneven character spacing when printing JTextComponent"
It is raised on the http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6488219
And currently in OPEN state, and raised on 31 Oct 2006 and mentions it was caused by fix 4352983.
So where do we go from here. It's not good because I have tried all later version of the JVM and the issue is still there.
Why? Because it hasn't been fixed yet. Read the bug report above, as it gives more insight -- and mentions the workaround is NOT good for existing code.
So the way forward is to use an earlier version of the JVM 5.
I download the JVM version 1.5.0 (starting version) and works Ok... I would probably think version prior to 4352983 would be Ok too.
Please vote for this.... We have a workaround (use older version of the JVM).
So I am very happy. -
After upgrading to mountain lion my calendar does not print in weekly mode anymore
after upgrading to mountain lion my calendar does not print in weekly mode anymore
I'm having the same problem with both my Vivotek wired network camera and Panasonic wireless network cameras. At first I thought this was an issue with the video framework in Mountain Lion, but if Firefox is working (I haven't tried it yet), it sounds like it may be an objective-c video library that has been changed. It's possible Firefox is using an objective-c interface that calls an objective-c function that isn't called by Safari or IP Camera Viewer, etc., (possibly a function that is on its way to be deprecated) or Firefox could use it's own library that directly calls the video framework.
Could be the Mountain Lion objective-c framework has a buffering issue.
Since this is occuring in both 3rd party software and Apple software, it sounds like it's an Apple issue. 3rd party applications typically utilize the Apple Developer objective-c frameworks to access video frameworks/libraries (for example, MJPEG). Thus, contacting 3rd party developers may not solve the situation (unless they can figure out a temporary bandaid--possibly figuring out the video framework call that Firefox uses and patching their software to do the same (not a simple task), but could still provide more feedback to Apple via their developer status.
Has anyone attempted to record from their cameras via iMovie or Final Cut Pro X HD? I will try mine later tonight to see if it records the hanging. If it does, then it's looking more and more like Apple's the culprit.
My suggestion is for everyone to file a bug report via http://www.apple.com/feedback/macosx.html -
HP Officejet J4680 All-in-One printer is ghosted and renamed "HP Officejet J4680 Series (Copy 1)?
Printer Model, Notebook or Desktop Model Number: HP Officejet J4680 All-in-One Printer
Operating System (including service pack revision): Windows 7 64-bit Home Premium Service Pack 1
Error messages: None
Recent hardware or software changes made to the system: None
Problem Description: HP Officejet J4680 All-in-One printer is ghosted and renamed "HP Officejet J4680 Series (Copy 1) and a new printer appeared: HPD8D625 (Officejet J4680 series). I don’t know how this all came about or why?
I used the HP HPD8D625 for a while but it took a long time to began to print and only buffered a small amount. I went back to my stand by printer, but know my wife want to use the wireless network to do her printing, so I have to fix it.
Connection Method: Wireless
Diagnostic Summary
Troubleshooting performed: Yes
First Wireless Network Report:
Everything: Passed
Signal Strength: Excellent
Other networks detected matching your network name (SSID): No
Configuration Summary
Network Name: Correct
IP Address: Correct
Config Source: DHCP
Communication Mode: Infrastructure
Authentication Type: WPA-PSK
Encryption: Automatic (AES or TKIP)
Second Wireless Network Report:
Network Name: Was different
Of course that disrupted the whole report.BH
Thanks for responding. What I did today was hard wire the printer to computer. then was able to get my original printer icon back and it was set as the default printer. I deleted the other icons, they were ghosted and I didn't what to use them. the one was a online printer going back to HP. Now I have to got my son to fix the remaining problem I have, with my messing around I somehow change the Network Name on the printer. He is a computer eng working on high tech cameras and also is the administrator of my machine. He has me locked out of administrative rights and for good reason, I wrecked a couple computers and when he built this one for me that was the rule. There is a little info that I don't have to finalize the last step in changing the Network Name back. I have run the printer from the printer control panel and it did find the correct Network and Network Name but is seemed like that is far as I could go. So I'm not that far from completing this project.
