#1665 — Addressing the printer -- Newbie

Hi all

I am a keen programmer in Visual Basic 6. I also tried Visual Basic dot.net 
but was appalled at the lack of printer support in dot.net.

I am thinking of learning Java, but would like to know if the language 
allows easy access to whatever printer is installed at a user site. 
Therefore I cannot specify the printer when writing the code and must rely 
on the operating system to route data to the printer.

Is writing reports to the printer (formatted and with columns and so on as 
in VB6) practical? With vb6 it is as simple as printer.print!

Thanks heaps

This tutorial maybe a good starting point:

Thanks John

I have looked through that and it does seem so much more complicated than 
Vb6!  I do not want to print a screen but I want to output the results of 
accounting calculations. I also want the program to automatically see 
whatever printer is connected to the user's computer and not bother with the 
dialogue box at all, if possible.

Cheers

This is not surprising, as Java printing support is cross-platform.

Several related components have extra support in this area:

Interesting; I almost always choose print to PDF. The dialogs are 
optional, but I never code it that way for myself.

Java's idea of printing is essentialy building a virtual screen
display and taking a snapshot of it.  You build it page by page the
same way you build a screen. You don't emit characters in a stream
with embedded control chars the way you did in DOS days.

Java has changed the rules on how printing works a number of times.

For some sample code, look at the VFRFlightLog program here;

Thanks for that Knute...

Takes me back to my own flying days in the UK in a Cherokee!

But what an incredible amount of code when I can address the installed 
printer with 2 lines of code in VB6!

Most of that was above my head...

I think it might be handy to show an actual example of how I currently print 
hard copy reports using VB6. This is an accounting program. The report in 
question lists particular transactions and shows them in columns. I have cut 
out all the code that does not relate to the printer

Printer.Orientation = vbPRORPortrait
aPageCount = 0
aLineCount = 0
'Report title and column headers here
For Looper = 1 to end of file
'get data from file here
    Aligned = Format(Looper, "###"): Printer.CurrentX = 20 - 
Printer.TextWidth(Aligned): Printer.Print Aligned;
    Printer.CurrentX = 33: Printer.Print TransactionCode;
    Printer.CurrentX = 48: Printer.Print TransactionDescription
    'various other columns
    'testing for page feed here
    aLineCount = aLineCount + 1
    If aLineCount > 56 Then
        Printer.NewPage
        '[Title and column header routine]
    End If
Next Looper

I am really looking for a simple example, such as how to align coulmns in 
Java and address the connected printer without having to specify it.

Java doesn't have the ability to print in a "text" mode.  The graphic 
mode is more complicated but it follows GUI creation and drawing very 
closely.

If you have a printer attached directly to your computer you could try 
this code;

import java.io.*;

public class test {
     public static void main(String[] args) throws Exception {
         FileOutputStream fos = new FileOutputStream("LPT1:");
         PrintWriter pw = new PrintWriter(fos);
         for (int i=0; i<50; i++)
             pw.println(i);
         pw.close();
     }
}

It's not going to work for network attached printers unless you can get 
a OS character device for them.
