PrintToPrinter method is not printing,just creating PDF file

[suhailtholakkal]

Please see my code below

Dim dfg As DataSet = searchobj.searchmethodsampleno(sampleno)
If dfg.Tables("entertest_table").Rows.Count > 0 Then
Dim reportviewerobj As New Form1
Dim obj As New CrystalReport_invoice
reportviewerobj.getDSprint(dfg, obj)

obj.PrintToPrinter(2, False, 0, 1)

it is just saving the contents as pdf file and opening the pdf file.But not printing.please guide

The PrintToPrinter method

"Prints the specified pages of the report to the printer selected using the PrintOptions.PrinterName property. If no printer is selected, the default printer specified in the report will be used."

So is it possible you are not specifying a printer but used a pdf driver to create the report?

I did not define printer name,so it must choose default printer,But why does this happen?..Printer is connected with my system over network.So,is it the problem?...or why does this happen?

You did not answer if you created the report on a pdf printer driver, nor did you extend the concept to tell us what the default printer driver is on your computer.

...But why does this happen?..Printer is connected with my system over network.So,is it the problem?...or why does this happen?

The only answer I can give you right now is that the quote I gave you is from the MSDN documentation on the method you were using. Why it works this way is like asking "why do we stop at a red light and go on green". The answer is "because that is the way it is".

Computers are really good at doing things you tell them. But if you don't tell them, they do not assume what you want. They just do what you told them before.

So check the printer it was designed for and see if it is still on your system. If so, then it is probably the one that is being used because you didn't tell it any different.

Some people have a policy to design Crystal reports using the No Printer option. I don't really know if this is better or not but it might be worth testing. Then the report might automatically pick up the default Windows printer.

Because "Default" means: that which will be used when you haven't specified otherwise.

So it's going to use the printer you specify for the print. If you don't specify one it will use the default printer specified in the report. If no default printer was specified for the report it will use the defauilt printer specificed in Windows. It will use the first printer it can along that chain and, if that is a pdf printer, it will create a pdf document because that's what pdf printers do.

The fact that you've got a real rinter attached, whether it's over a network or locally, is irrelevant unless that printer is the first one found along the aforementioned chain.
