Print to receipt printer

extremeJ — Mon, 31 Jan 2011 11:16:31 +0800

I have problem when sending text to a receipt printer.
I install the printer (Epson TM U950) using slip driver. When I do a test print, the printer prints in slip, which is OK.

The place where I have problem is with my Java swing program.

When I send the text to the printer for printing, it ALWAYS prints to the receipt+journal instead of slip.
I've checked and confirmed that the paper source has been specified to Slip(Eject) in the printer setting, and the correct printer is chosen when printing.
However, the printout always go to receipt/journal.

Anything I missed out? Attached is my code for printing.

CODE

private static boolean printToPrinter(String msg) {
PrintService pserv = getDefaultPrintService();
DocFlavor[] dfArr = pserv.getSupportedDocFlavors();
if (dfArr != null) {
for (int i = 0; i < dfArr.length; ++i) {
System.out.println(dfArr[i].toString());
}
}

DocFlavor myFormat = DocFlavor.BYTE_ARRAY.AUTOSENSE;

// Create a Doc
Doc myDoc = new SimpleDoc(msg.getBytes(), myFormat, null);
// Build a set of attributes
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

if (pserv != null) {
DocPrintJob job = pserv.createPrintJob();

try {
job.print(myDoc, aset);

} catch (PrintException pe) {
pe.printStackTrace();
}
}
return true;
}

where msg is the text I want to print to the slip paper of the printer.

Please help

in dilemma now...

I got an offer from a big company here as a IT dpt personnel, will be dealing with SAP related project.

However the offered salary is lower than my current salary (yes, i have a job now, as java prog in a small comp).

This offer is contracted, and after the contract period, will go thru another one year probation if they still want me.

Shall I take it?

Do I need a better antenna?

Broadband provider
ISP/package: Streamyx
Location: Kuching, sarawak
Have you called your ISP's helpline?:

Personal equipment
Modem: aztech dsl605ew
Router: same as above
Firewall used: yes

Problem details
Currently I'm staying in a 2 storey house, with my wireless modem/router in ground floor's study room.
One desktop is connecting to that rt using lan cable.

On upper floor, I have 1 laptop (centrino) and 1 desktop (using wifi usb dongle). My laptop's position is fine in receiving the wifi signal (3 ~ 4 bars in vista), the problem is on my desktop.

My desktop is struggling in receiving the signal, no matter how I position the usb dongle and the wireless router antenna position. The max it gets is 1 bar, most of the time no connection. So my question is, if I replace the antenna with something like D-LINK ANT24-0700, can the situation improve?
If not, is there any workaround? (Moving the router/modem or the desktop using wifi is not an option )

p.s: position of the three comps:

assume the house is square, each side marked as 1 2 3 4 (clockwise), the desktop using wifi is at upper floor position 1, whereas the router is at lower floor position 3.

1 2
4 3

Comp cannot start

I have one problem here.

There is one time that my CPU shut off itself, like electricity shortage.

After that trying to switch it on, after a few seconds, shut off again.

Try to swtich it on again, no more response. Press the ON switch no light fan not spinning everything juz quiet.

Send to the shop and inspect, they replace a PSU but still the same. RAM checked on other pc, ok.

They said is either motherboard or processor (or both) is faulty.

The problem is, how do i confirm whether it is motherboard AND processor? I do not have another spare parts to test (so does the shop I sent my CPU to...)

Anyone can teach me how to test?

CPU spec:
- Intel Celeron 2.4GHz (478)
- Foxconn SiS MB
- 2x 256MB DDR RAM

Streamyx - self installation

extremeJ — Wed, 26 Dec 2007 17:24:41 +0800

Hi everyone!
I juz applied the streamyx through online application.
But can't seem to find any option to choose to do self installation (to save the RM88).

Any idea how to opt to install by myself? i'm choosing the RM77 (merdeka bash) package.

Thanks~
