Printing second time fails

[Rick Lederman]

I am using a PrintDocument and PrintDialog to print. The first time that I
print it works, but when I try to print a second time without exiting the
entire program I get an "InvalidPrinterException was unhandled" error. The
error happens in the third line below. The details of the error are below
my signature. Help?

PrintDialog1.PrinterSettings.PrinterName = sLabelPrinterDeviceName

PrintDialog1.Document = PrintDocument1

PrintDialog1.Document.Print() ' the error happens in this line



Any ideas?

[Guest]

Rick,

I suspect the problem is in the printdocument's print event.
Could you please post the code in that event.

Ken,

Thanks for the help as I am at a loss. Here is the code:
The code looses its format here ... should I post the code some other way?

Ken,

I just took ALL of the code out of the PrintDocument2_PrintPage event and it
feeds a page the first time that it is run and has the error the second
time! So, it must not be the ocde in the PrintPage event?

Private Sub PrintDocument2_PrintPage(ByVal sender As Object, ByVal e As
System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument2.PrintPage



Here is the code that I use in the Button_Click event (the end of the code
anyway)

If chkLandscape.CheckState = System.Windows.Forms.CheckState.Unchecked Then

PrintDocument2.DefaultPageSettings.Landscape = False

Else

PrintDocument2.DefaultPageSettings.Landscape = True

End If

PrintDialog2.PrinterSettings.PrinterName = sLabelPrinterDeviceName ' I set
this to the printer name very early in the program

PrintDialog2.Document = PrintDocument2

PrintDialog2.Document.Print() ' this line works the first time, and errors
the second time. Then I must restart the program.

Rick,

I see you are using a variable iCurrent to keep track of the
record number. I do not see where you reset iCurrent to the begining of the
list when you print the second time.

Ken,

I reset it at the beginning of the CmdPrint_Click event. THat is the button
that I click to do the print job. And, as I said, I deleted all of the code
in the PrintDocument2_PrintPage event and it still fails. Here is all of
the code in the CmdPrint_Click event.

System.EventArgs) Handles cmdPrint.Click

Rick,

Instead of PrintDialog2.Document.Print() try printdocument2.print

Ken

 

[Rick Lederman]

Again, does not work. That is strange, the first thime that I print it
everything works. Click the print button again and I get the same
"InvalidPrinterException was unhandled" error. Underneigh that it also says
(same as before) " Settings to access printer 'Samsung ML-2250 'are not
valid." ...

To test things I put the following into the program

If PrintDialog2.PrinterSettings.IsValid = True Then

PrintDialog2.Document.Print() ' this was already there

End If

And, imagine that the IsValid returns False on the second print job. So the
question remains what makes the PrinterSettings become false after using it
once?

And, during a program run, I set the printer to a different printer, and the
first time that it ran it printed OK, the second time that I tried to print,
IT RETURNED TRUE and ran OK! And it continues to work for the new printer.

So, I change the printer selector back to the original printer. And it
WORKS ... these kinds of problems I really don't need, but for now it is all
WORKING ...

Ken, thanks for your help. I have no idea what was going on within this PC
but simply printing to a different printer then switching back to this
printer seems to have fixed it. The magic of Windows!
