i am developing a web application and uses jsp page to print a payment receipt.
everything works good, but printer scrolls complete sheet after printing first receipt. so need scroll back manually every time i print a receipt.
So, how to stop printer from scrolling entire sheet.
I have a project to create an application where you can print all the detail to be written on a receipt (no more manual writing). I already have blank receipts. All I want to know is how to do that printing the details at exact position in my blank receipt. I'm starting to read about Jasper Reports but I don't know how it will work since most of its example are creating template.
View Replies View RelatedBasically I am trying to make a POS system and need a way to print a receipt whether there are 1 items sold or 50. So I used a Arraylist. This is the format for the printer that is needed:
printer.printNormal(POSPrinterConst.PTR_S_RECEIPT, " 2 200 Tx Hashi Chop Sticks" + LF);
This is what I tried to do:
ArrayList<String> receiptLine = new ArrayList<>();
public void captureSales(){
receiptLine.add("Test");
System.out.println("Size of the receipt list is: "+receiptLine.size());
System.out.println("Element at index 1: " + receiptLine.get(0));
printer.printNormal(POSPrinterConst.PTR_S_RECEIPT, " " + receiptLine.get(0) + LF);
Error:
Size of the receipt list is: 1
Element at index 1: Test
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

View Replies View RelatedI have a JSF page (called MainPage) with a commandButton: clicking on it, I open a modal panel with a <Rich:fileUpload> component, related to a listener in corresponding bean.
When I start to upload a file, page MainPage starts to refresh, but I would like to prevent this because it's not necessary.
I tried to "play" with <Rich:fileUpload> property values, but nothing seems to work and I don't know what to do anymore.

why my code is not printing the matrix and sum?
The Java-program Matrix below first asks the user for the number of rows and columns in a matrix. After this the program asks for the values of the elements. Finally, program prints the elements of the matrix and their sum on screen. Your task is to create the missing methods. Check the example print to see how to modify the print. When printing the matrix, values on the same row are separated using tabulator.
Program to complete:
import java.util.Scanner;
public class Matrix {
public static void main(String[] args) {
int rows, columns;
Scanner reader = new Scanner(System.in);
System.out.print("Type in the number of rows: ");
[code]...
Write the missing methods here / Methods are written in the text box below.
Example output
Type in the number of rows: 3
Type in the number of columns: 4
Type in the element 1 of the row 1: 1
Type in the element 2 of the row 1: 2
Type in the element 3 of the row 1: 3
Type in the element 4 of the row 1: 4
Type in the element 1 of the row 2: 5
[code]...
Matrix:
1 2 3 4
5 6 7 8
9 10 11 12
Sum of the elements of the matrix: 78
my code
import java.util.Scanner;
public class apples {
public static void main(String[] args) {
int rows, columns;
Scanner reader = new Scanner(System.in);
System.out.print("Type in the number of rows: ");

I have a print button as below
<p:commandButton id="printit" value="Print" type="button" icon="icn-print">
<p:printer target=":topForm:data" />
</p:commandButton>
when i click print button only top half of the page is getting printed and bottom half is pushed to next page. How do i fix this issue.
java program that will determine if the matrix is a lower or upper triangular matrix. I only need to use java.util.Scanner;.

I used the PLPDF software to generate a blob in PDF format in PL/SQL. I can open it in a browser but I would rather send it directly to a printer from PL/SQL.

I was wondering of I can use JAVA in Oracle to send the blob to a printer.
I have some troubles rendering images to the printer, any resolution does not work, even 72 in PDF printer does not work, the image is crappy.
I use the following code but the result is not good. I mean the image quality is not acceptable.
img=new ImageIcon("c:\test\m.jpg").getImage();
scale=72/300d;
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
I've also tried :
img=new ImageIcon("c:\test\m.jpg").getImage();
AffineTransform aft=g.getTransform();
double scale=aft.getScaleX();
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
The result is the same even if I change the image, very poor and unacceptable!
