Printing from an applet on a Mac

Printing from an unsigned applet is allowed by the java plug-in. When a print request is made it pops up a confirmation dialog after which the print job goes through on Windows. On a Mac, however, a security exception is thrown after the confirmation dialog:
java.security.AccessControlException: access denied (java.net.SocketPermission localhost:631 connect,resolve)
The entire stack trace is copied at the end.
It appears that the applet is trying to open a connection to port 631 on localhost (Port 631 is the standard port for the IPP protocol). Usually an applet is only allowed to open a connection to the host that it came from (not localhost in this case). Therefore, the exception seems reasonable. However, when the print request is sent a second time the print job goes through! I don�t know why!
Has anyone encountered this problem on a Mac (OS 10.4.7; Java version 1.5.0_06) ? Is there a solution? It works just fine on Windows!
Thank you!

Yes!! This is VERY HARD to find. I literally spent ONE YEAR looking for solutions to my printing problems until I found this little drop-down box in the middle of the second or third dialog box that the Mac OS offers you when you're printing. If you're still not finding it, ask us again. I'm not in front of my Mac right now, and I'll be glad to give you detailed instructions. I tried several hundred different things before I could get my photos to print well, and the secret was always right there, hidden in that tiny drop-down menu in the center of that dialog box. VERY frustrating.

Printing from trusted applet

Hey boys and girls.
I need a litle help. Does someone has expirience with printing on local raw printer from browser? I think that is possible, but since I am new with Java and some time to learn it good, I will relly on your help. It would be a super if your have a piece of code. Again, we are talking about raw dot-matrix printers and they will be used for printing data for documents like passport, personal ID's driver licence. You know, the old style... Thanks

When i try to print from Parallels Desktop to my mac printer, it cannot convert the prescript file. what should i do?

i use Quickbooks accounting for windows and when i bought my new mac i had to buy parallels desktop so that i could continue to use my accounting software. it has been working since then and i dont know what happened, but now when i print something i get a message saying that states "Unable to Convert The ProScript File".
Help Please!!!
Niko96
i need this fixed a.s.a.p!!!!

I don't have Parallels; I use Fusion. And in Fusion you have the option to use the installed printer is OS X to print. I have seen printing from Windows 7 to the Mac printer result in errors and there is a chance you are having the same issue.
If Parallels has the same facility where you can use the Mac's printer then I would suggest that you install a Windows driver for your printer in Parallels and not use the Mac printer. This should stop the conversion error you are getting.

Printing from Win PC to a Mac Printer

Hi all.
I have an Epson R300 connected to the USB port of my iMac, and shared through the System Preferences -> Printer and Fax -> Sharing options, and a Win 2000 PC in local network with the iMac through the ethernet ports.
The PC can see the iMac and exchange documents with it, but I am having problems when printing from the PC to the R300. That is, when I try to set up a network printer using Bonjour for Win, everything is OK, except that at the end of the procedure a message warns me that I have not the rights to use the printer. I am logged as administrator on both computers, which additional rights do I need. Also, I restored the disk privileges where some printer file access privileges were corrupted, but had no change.
I also tryed to use the procedure suggested in MacHelp, but I don't know what a SBM/CIFS printer is and how to set up it on the PC.
Thanks a lot for help. Regards.

Double sided printing from an Epson sx425w in mac

Hi everyone,
I've been reading posts by others regarding problems with double sided printing on mac. Since I changed to a mac, I havent been able to print double sided from my epson sx425w printer. This can be quite annoying if you a lot of pages to print. The double sided print option is just disabled so I cant even select it and I dont have the option of "Duplexer" or "Duplex Printing" as suggested in other posts. Besides, I've not been able to use my scanner since upgrading to Mavericks-I know others have had similar problems too.
Anyone come across similar problems?
Thanks

Thanks for your reply. I think epson has just released a new scanner driver which I've downloaded and is now working. As for the printer, they said it's not possible to print double sided from this particular model in mac as it does not have the duplex unit. Hence the only solution is to print from windows or buy another printer with a duplex unit. I only found out after posting the question. Here's a link to the scanner software-http://esupport.epson-europe.com/FileDetails.aspx?lng=en-GB&data=FCFfEfoyEiFBBDU 002FXyeTVD1rAPvGEp+uonLZf8Ez0bAEU003D&id=377764

Printing from Airport Extreme for both Mac and PC

I have both a mac and a PC. Both are connected to the internet using the Airport Extreme. Here's my problem. Currently I can only print from the Mac but not the PC. I was told that I would be using the airport extreme I would be able to use one printer for both computers. The printer I am using is an HP Office Jet 6310, which is compatible with both a Mac and a PC. Can anyone help me?

I recently purchased a Canon Pixma MP610 and it is connected to an AE. My Macbook prints fine to it. My PC laptop doesn't. I used to have a Canon Pixma 1600 that printed fine for both computers (I used iFelix's 1004.html steps to install for the PC)
I have tried the Add Printer on the PC using the same 1004.html steps with no luck. I have also used the 1008.html steps to install using the Bonjour Wizard with no luck.
When I say no luck, I mean it sees the printer, it has the proper drivers, but when I print a test page, it can't connect.
I Add a Printer and test and it fails, I then delete the printer and install it a different way. The weird thing is hours later, the test page will be there sitting on my printer. But I don't know why it took so long or which printer install method worked.
I have now installed 4-5 different printers and hit Test Page on all of them. I named each printer something different so in case the Test page comes out, I'll know which printer works.
I'm almost there I feel, but just can't get it.
Any suggestions iFelix or anyone else?

Failure to print from PSE 9.0 on MAC to Epson XP-800

I cannot print photographic images with my desktop MAC (OS X10.8.4) from Photoshop Elements 9.0 to my new Epson XP-800 printer. Printing is not a problem with Word text or images from iPhoto- it is only with PSE that there is a problem. The problem persists even if I try using a cabled connection rather than WiFi. I have ensured latest software from Epson has been downloaded. This problem did not occur when using the same system with the previous printer (Epson Photo Stylus 1290).
Any suggestions for solving this rather than just a workaround of moving the edited PSE image back to iPhoto & printing from there (which admittedly does work but shouldn't be necessary).
Grateful for any help.
Stuart

Hi Barbara B
Thanks very much for this suggestion.
I followed this advice, both deletions and permission repairs. This did allow me to print from PSE for the first time - very pleased with this. Unfortunately the colour reproduction has now gone haywire (having been very good) and there are vertical lines on prints - this now applies to both PSE & iPhoto (the latter worked well before)
Any further suggestions? I feel we are close to cracking it but do not really understand what to try next. Please help if you can. Many thanks.
Stuart

Provider !DOCTYPE ... error while printing from an applet

Hi,
I'm developing a (signed) applet that requires access to the local printer. The applet will parse an XML document using [Flying Saucer|http://xhtmlrenderer.dev.java.net/] . I'm developing it in Eclipse.
When I run the applet from Eclipse, everything works fine, and a print is produced by the printer. I then export the applet as a jar file, sign it, and put it on a local server. When I run the applet in any browser (whether its IE or Firefox) the thing crashes with this error:
Exception in thread "AWT-EventQueue-2" javax.xml.parsers.FactoryConfigurationError: Provider <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> not foundThis exception seems mangled to me - shouldn't it produce a classname as opposed to the DOCTYPE declaration String?
I've signed all the jars required (Flying Saucer's core-renderer.jar & jtidy.jar), accepted them in the browser. All dependencies should therefore be resolved.
To be sure: I am NOT referencing the DOCTYPE anywhere in the Java code, nor in the HTML source document, nor in the HTML document hosting the applet. In short, I cannot find any trace of the DOCTYPE given in my source code. Where does it come from?
Here's a stack trace. Hopefully someone has a great tip! :)

The problem was with the entity resolver, which points to the w3c.org web site. The access to the reference DTDs on this site has been restricted for application use. The solution was to implement my own entity resolver.

Javax.print problems on applet - bug on mac os implementation?

Dear All,
I am working on an applet and application that include a print function and I get a weird behaviour on MacOS in applet mode (both with Safari and Firefox - Mac OS X Versione 10.4.9 (Build 8P135) ). In contrast, things work fine on Windows XP (both Explorer 7 and Firefox with Java Plug-in 1.6.0_01) and even in MacOS when using the application.
The problems are:
- the print dialogue goes on and off a few times before letting the user interact with it
- the page format in the dialogue is set to A5 (instead of the printer's default)
- there is a small empty window appearing together with the dialogue and not disappearing even after the applet is closed
Is this a known problem? If so, are there work-arounds?
(I had no luck on Google about this)
To reproduce the problem I created a stripped down version of the applet, in 2 files, I report it at the bottom of this message. I am using a modified version the PrintUtilities class from http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-Printing.html
Am I doing something wrong? Or shall I consider submitting a bug report?
Any suggestion is welcome! Please let me know if I should provide more detailed information.
Thank you in advance,
Enrico

How to print from an applet to console

Hi,
I'm passing my applet a parameter then I'm trying to print it using System.out.println but I don't see any output. My web app is deployed in weblogic 7. From the html page I pass in applet param but I don't see any out put in weblogic console.How can I see the output. here is what I have in my html page.
<APPLET codebase="classes" code="taqDingHILoNew.class" width=550 height=420
archive="../../../lib/EspressAPI.jar">
<PARAM name="cabbase" value="../../../lib/EspressAPI.cab">
<PARAM NAME=FontName VALUE="Arial" >
</APPLET>
And here is code for my applet. Any help would be greatly appreciated.
public class taqDingHILoNew extends Applet implements ActionListener{
TextField tf;
public static void main(String argv[]){
taqDingHILoNew chartFrame = new taqDingHILoNew();
Frame frame = new Frame();
frame.setLayout(new BorderLayout());
frame.add("Center", chartFrame.createComponent2(null));
frame.pack();
frame.show();
public void init() {
setLayout(new BorderLayout());
String param = this.getParameter("FontName");
System.out.println("GOT APPLET PARAM " + param);
add("Center", createComponent2(this));
Component createComponent2(Applet applet) {
QbChart.setChartServerUsed(false);
setLayout(new BorderLayout());
// primary axis value column 3
// secondary axis value column 2
// ColInfo(series, category, sumby, primary_value, secondary_value)
QbChart chart;
String param = this.getParameter("FontName");
System.out.println("GOT APPLET PARAM " + param);

If you're using the java plug-in, you can right click on the java icon in that system tray to the bottom right of the screen if you've got a normal set-up. Also I think you can invoke it via the start menu.
If you're not using the plug-in, MSIE and Netscape both have "show java console" options. However on MSIE I think you have to turn on an Advanced Option first that lets you see the "show java console" option. It's a pain.
Of course, if it's an applet, normally you're not the one viewing the console at all. It's the user who sees it. You only get to see the client java console if you happen to be the user.

Has anyone had a problem with printing from Elements 9 on a MAC?

When I first installed Elements 9 and tried to print, all I got were blank pages. I contacted adobe support and after an hour on the phone, she referred me to the next level. I then received an email from them asking me to call them and in the meantime, they suggested things I shoud do. I did what they suggested and it worked. I was able to print. However, I was unable to indicate the type of paper or resolution that I wanted to print in. So, I called them again. It seems that on a windows PC, they give you five options for printing: 1. Select printer, 2. Select Settings, 3. Select paper size, 4. Type of print, and 5. Select Print size. On a MAC, You get only three options: Select printer, Select paper size and Select print size. Does anyone know another way to select the settings and type of print. I have been using Elements 4 for years with no problems. Elements 4 gives all the options. I don't understand why it is not the same in Elements 9.

Thank you so much. You have solved my problem. I never thought to click the down arrow. In all the time I have been printing, on any program, the entire window opened up when I clicked on the print button. This one never did. I don't understand why Adobe support never told me about that when I called them.

Printing from photoshop elements 6 for mac

I have an i-mac and use photoshop elements 6. I have created hundreds of images but when i have contacted printers to print cards i created from these images using indesign i have been told by many printers that there is an issue regarding RGB vs CMYK . Where and how can i get my RGB images printed for a reasonable price. billrene

The main question I have is whether or not there is an efficient way to get a rgb images printed. I have an Imac whose screen is a rgb pattern so even if i convert the images to cmyk (which i can do in a couple different ways -- through indesign or putting the images in photoshop). however since my sreen is a rgb format i can not acurately see the changes I have made through converting to cmyk. also i have several hundred images i have created and would rather not have to convert them all before printing. I have had problems finding a printer that will even attempt to print rgb images. I have checked at kinkos as well as several print shops in montana where i live. each time i am told they can not print rgb. the images I sent to those printers were unusable because of the color distortions. When I talked with some one in the Apple store they suggested I get a different computer. It has also been suggested i get a printer that could be calibrated to the rgb format and i could print the images myself. another suggestion i received was that there may be a calibration program/software that i could use to make the converesion. Help. billrene

Printing from a applet toolbar the image displayed in the applet

Hi ,
I have a JApplet which displays a tiff image. The applet uses JAI API and Java 2D for printing. I can zoom in . zoom out , invert the image and I am printing the displayed image also .
In the action handler class for the print button , I have made an inner class implementing printable and executing the print function.
I am doing printing via a separate thread as i don't want my action handler class to keep waiting till the image gets printed . The user should be able to manipulate the image after it has clicked on the "ok" of the print dialog, while the image is being printed. This is the reason for printing the image in a separate thread
and the actual printing process is a synchronized method called by the run method of the thread .
If I click on print button twice , one after another , the second image gets printed only after I get a response from the printer that image has been printed as expected (as the print method is synchronized ).
In the action handler class of print , I do not call join on the thread as I do not want it to wait for printing to get over ( printing of a tiff image actually takes a long time ?? )
Is there anyway to make the threads independent of the main applet . Like after firing the print command , if I close the applet and I haven't got a confirmation from the printer, I get a blank page or nothing but i get a response message from printer that printing is done .
Is it essential for a thread to wait till the printer sends a response that printing is over ?
Similarly , If after firing the printing command and without waiting for the confirmation from the printer , I refresh the applet , proper printing does not occur but I get a message from the printer that printing is done .
If i use synchronized method for printing and wait till the printer response from the printer comes without closing or refreshing the applet , printing occurs fine .
Can anyone please tell me what is actually happening and is there a better way to print and that printing occurs after the print command has been fired irrespective of the applet ?
Regards , Navneet

Hey can you send me the code for the same. I know its been a long while, but I am new to JAI and need the same stuff u coded. u can mail it to me on [email protected]
Thanks in advance.
