Problem printing with GDI+

Question

I'm having trouble printing from my app in c#.

First of all, I am connected to an HP Laser Jet 6 on a network.

I am trying to print out a doc generated from one of my programs. The print preview dialog takes a while (long while) to come up and show the doc.

However, when the doc appears, it is there as it is drawn in the program using GDI+.

However, when the doc finally gets sent to the printer, the page is blank.

SO, I typed a few letters on a blank notepad doc, sent it to the printer and it worked just fine, and didn't take forever either.

I don't know why it takes so long to show the preview. Before I was connected, the preview came up instantly.

So I don't know what my program is doing wrong.

I did another test. I had the words "Header" and "Footer", with several rows sandwiched in between.

The words "header" and "footer" were printed. They were in Arial font size 12. The rows were printed in Arial size 7. So I'm changing everything to 12 to see what happens.

Then I tried to put everything in Arial Font size 12, and nothing happened. The words Header and Footer still printed, and the space between them remained the same, even though there should be 12 lines of text in between.

The network printer is the only printer installed.

I also connected the printer directly to my machine but I got the same result so I know it's not a network issue. Someone suggested that perhaps the printer (HP LaserJet 6L) may not be compatible with GDI+. So a little bit later I am going to borrow a newer printer and see what happens. I know that I have never had any trouble printing with .NET before and now is not the time because I have about a week week in a half to finish up.

Here is the calling code. string [] names = new string [40]; for ( int i = 0; i names[i] = Michael Jordan ; DummyReport report = new DummyReport ( string .Empty string .Empty names); report.PageBreak = 12;//this will create a new page after 12 lines are printed report.Print( true );//true means that the PrintPreviewDialog will appear.

Thanks for the reply! Here is the function that brings up the PrintPreviewDialog: /// /// Prints an object. /// /// bool public override void Print( bool showPreviewDialog) { ROW_COUNTER = 1; PrintDocument document = new PrintDocument (); if (showPreviewDialog) { PrintPreviewDialog dialog = new PrintPreviewDialog (); document.DocumentName = name; document.PrintPage += new PrintPageEventHandler (printObject); dialog.Document = document; DialogResult result = dialog.ShowDialog(); } else { document.Print(); } } //Here is the code that is called when the printpage event fires. It appears just fine when the printpreviewdialog appears but when it prints only the words header and footer appear on the page. protected override void printObject( object sender System.Drawing.Printing. PrintPageEventArgs e) { float x = 0.0f; float y = 0.0f; e.Graphics.DrawString( Header  new Font ( Times New Roman  12.0f) Brushes .Black new PointF (x y)); y+=20.0f; while ((ROW_COUNTER % PAGE_BREAK != 0) && ROW_COUNTER { e.Graphics.DrawString(names[ROW_COUNTER - 1] new Font ( Times New Roman  12.0f) Brushes .Black new PointF (x y)); y += 10.0f; ROW_COUNTER++; } if (ROW_COUNTER { ROW_COUNTER++; e.HasMorePages = true ; } else e.HasMorePages = false ; y += 20.0f; e.Graphics.DrawString( Footer  new Font ( Times New Roman  12.0f) Brushes .Black new PointF (x y)); } }

Could you please post the code used in sending the doc to your networked printer?
