Printing Crystal report thro' ASp.Net

Hi,

I am develpoing an intranet application using ASP.Net which uses crystal reports. The IIS is installed in my machine. But the printer is connected to some other. When I try to take printout it raises an error as:

Error in File C:\DOCUME~1\banupriya\ASPNET\LOCALS~1\Temp\temp_2924ba53-898a-4038-a402-b1504cbdbe18.rpt: Request cancelled by the user.

The code I used is:

crpt.PrintOptions.PrinterName = "\\banupriya\hp LaserJet 1300 PCL 6"
crpt.PrintToPrinter(1, False, 1, 1)

Note: This code works when I connect & install the printer to my machine.

Can any one please say me how to fix this problem.

Thankyou for your reply.

Hi..

Use this
crpt.PrintOptions.PrinterName = "hp LaserJet 1300 PCL 6"
instead of crpt.PrintOptions.PrinterName = "\\banupriya\hp LaserJet 1300 PCL 6"
crpt.PrintToPrinter(1, False, 1, 1)

It will work.
Printer should be installed on your machine and printer may be anyother machine in network.

Hi

I tried with

crpt.PrintOptions.PrinterName = "hp LaserJet 1300 PCL 6"

or

crpt.PrintOptions.PrinterName = "hp LaserJet 1300 PCL 6 on Bharath"

or

crpt.PrintOptions.PrinterName = "\\Bharath\hp LaserJet 1300 PCL 6"

Since the printer is installed in machine Bharath and is connected to the network with the share name: hp LaserJet 1300 PCL 6 on Bharath.

But the print is not functioning.

It raises the error:

Error in File C:\DOCUME~1\BANUPR~1\ASPNET\LOCALS~1\Temp\temp_72da1e2d-ec31-4955-8666-378f164f2274.rpt: Invalid printer specified.

Hi , you are missing something somewhere.

Steps
1) Go to My Computer - > Control Panel - > Printers ->
Now see there is any printer connected to your machine ?
If yes then there is printer name , Copy that name to your code.

If no printer is connected to your machine the connect it with 'Add Printer' (Ask it support how to add printer in yoyr machine)

No you will get Printer Name.

Use that name in your Code.

It will Works 101%

I was facing same problem for 2 days then i got this solution.

If you have problem ask me.

Hi

I have the printer set to default named hp LaserJet 1300 PCL 6 on Bharath

hence I specified the printer in code as

crpt.PrintOptions.PrinterName = "hp LaserJet 1300 PCL 6 on Bharath"

is it correct?

but on executing, I get the error msg

Error in File C:\DOCUME~1\BANUPR~1\ASPNET\LOCALS~1\Temp\temp_bbd09d23-df2d-49fc-aef3-448285e29365.rpt: Invalid printer specified.

Pl go step by step

Steps
1) Go to My Computer - > Control Panel - > Printers ->
Now see there is any printer connected to your machine ?
If yes then Press F2 and copy that name to your code.

If no printer is connected to your machine the connect it with 'Add Printer' to your machine and do the same procedure press F2 and copy name of printer.

Use that name in your Code.
It will really work

hi

I tried the same way but the error is again & again raising.

Note: F2 key press has no effect.

Steps
1) Go to My Computer - > Control Panel - > Printers ->

Now Tell me what are there after clicking to Printer ?

Please give me all names.

hp LaserJet 1300 PCL 6 on Bharath

and

Add Printer


Note: The printer name is hp LaserJet 1300 PCL 6 connected to the system Bharath. My machine name is Banupriya

Do one thing ,
Delete that printer hp LaserJet 1300 PCL 6 on Bharath from your Printer.

Now add one again using 'Add printer' with name only "hp LaserJet 1300 PCL 6" Take help from your compan's IT Support people. The name must be "hp LaserJet 1300 PCL 6"
Then try by using Printer Name name = "hp LaserJet 1300 PCL 6"
It will work.

On my machine printer name is "hp LaserJet 1010" and "Add Printer" . Its working properly when i used name = '"hp LaserJet 1010"

Try out this.

Hello Did you get solution
Do one thing

In Control Panel -> printer

Right click on this 'hp LaserJet 1300 PCL 6 on Bharath'
Go to Peoperties -> General tab - >
Change this name 'hp LaserJet 1300 PCL 6 on Bharath' to
'hp LaserJet 1300 PCL 6' , Dont keep any blank spaces to left and right.

And try to use this name to printer name.

Thanks

I think you didn't understand the problem. I have exactly the same.
It work fine with a local printer but if you want to use a printer on the network it doesn't work !
If he change the name of the network printer in the parameters his computer won't recognize the printer after this.
I think it's a bug (one more !!) of crystal !!
But if someone has the solution it could be great !!

Thanks

Nicolas

The problem is a security problem.

I copied for you the relevant section from this document by crystal solutions:

Printing the report on the server side
(PrintToPrinter method)
Server side printing results in the report being generated on the Web Server and
being printed to a printer that is installed to the Web server.
Printing to a printer installed to the Web server requires that the process under
which ASP.NET is running have sufficient permissions to access Network
printers. In order to provide these permissions, changes to the account that the
ASPNET worker process runs under are necessary as well as changes to the
registry on the Web server.
By default, ASP.NET runs with the permissions of the local “machine”
(ASPNET account for the ASPNET worker process) account. In order to
achieve network printing through IIS (Internet Information Services), the
Framework should be run under the local SYSTEM account. To make this
change, it is necessary to edit the default configuration settings in the
Machine.config file. This file is located by default at:
C:\WINNT\Microsoft.NET\Framework\<VersionNumber>\CONFIG\
Where <VersionNumber> is the version of the .NET Framework installed to the
computer. The account setting is contained within the <ProcessModel> tag of
this file. The default setting for the account is:
userName="machine" password="AutoGenerate"
This can be changed to:
userName="SYSTEM" password="AutoGenerate"
Then save the file.
It is now possible to give the local SYSTEM account on the server permissions
to print. If the printer is a network printer, we must expose the network printer
to the local SYSTEM account. The reason behind this is that when a printer is
installed to a computer, the settings for this printer are stored in the registry
under the HKEY_CURRENT_USER registry hive (Registry file). The IIS
process will never use this registry hive since it always runs under the context of
the local SYSTEM account and cannot be logged onto a server as a “Current
User”. By default, the SYSTEM account does not have any printers set up in
the registry. There are two Microsoft knowledge base articles, Q152451 and
Q184291 that explain how to expose the printer settings to the System account.
Both of these articles require editing the registry on the Web server and copying
the printer settings from the HKEY_CURRENT_USER hive to the
HKEY_USERS/.DEFAULT hive

Dear Friends,

Iam sorry for the delay reply.

1. robinash, what you says is correct, the network printer won't recognize without network path.

2. if you want to view the installed printer list, refer the following code.

(But It's not a bug).

Code:

---

Imports System.Drawing.Printing

Dim fwPrintSetting As new System.Drawing.Printing.PrinterSettings
Dim nCnt As Integer

        With cboPrinter.Items
            For nCnt = 0 To (PrinterSettings.InstalledPrinters.Count - 1)
                .Add(PrinterSettings.InstalledPrinters.Item(nCnt))
                fwPrintSetting.PrinterName = fwPrintSetting.InstalledPrinters.Item(nCnt)
            Next
        End With

---

3. The reported error is

"Error in File C:\DOCUME~1\banupriya\ASPNET\LOCALS~1\Temp\temp_2924ba53-898a-4038-a402-b1504cbdbe18.rpt: Request cancelled by the user . "

a. Make sure the security permissions are correctly.

b. Do Testing printout from other reports.

Thanks.

I have tried all the possible solutions to this problem that were listed in the posts previews to this one and It simply doesnt work.

I have changed the Machine.cfg and made all the changes to the registry and It still doesnt work.

The code is very simple:

crystalReport.PrintOptions.PrinterName = @"\\Server\Server Printer";
crystalReport.PrintToPrinter(1,false,0,0);

But I still get the following Error:
CrystalDecisions.CrystalReports.Engine.InternalException: Error in File C:\WINDOWS\TEMP\temp_b29aeb15-c5f3-4426-a063-4edf6c5cb3b8.rpt: Request cancelled by the user.

If anyone has a solution for this that works Please post it thanks!

Hi,

I have the same problems. I have modify my machine.config with userName="SYSTEM" and modifiy also my registry HKEY_USERS\.DEFAULT ... but I see still my local printer. I have reboot my machine, reregister aspnet.
Any other idea ?
Thank You

i have the same problems.
I setup my Web application to print from a WebServer. I have setup the
account so that it can print correctly. However, it can only print if
the printer is connected to Win98 but if the

printer is connected to Win2000/XP, it throws an error:

Error in File xxx Request cancelled by the user.


Here is my code to print over the web:

Dim x As ReportDocument = New ReportDocument()
x.PrintOptions.PrinterName = "xxx"
x.PrintToPrinter(1, True, 1, 1) '(eror on this line)


Please give me a solution
thank u all

Hi achonk81 and all!!

Not sure this may help you, but this is how I solved the problem:

Instead of trying to print the crystal report by using PrintToPrinter method, I export immediately the report in PDF. After the export, the report will be viewed in Acrobat Reader, and the user will be able to save the report wherever he wants or to print it, and he can choose on which printer he wants to print the report, comparing with the PrintToPrinter method for which you must specify a printer. And PDF display the report as you designed it, with page break. It is much more user friendly than the crystal report web viewer and really less trouble. Here the web site where I found how to export the report in PDF. If you put directly the code in the Page_Load function, the report will open by default in PDF.

Hope this help and that I'm not too late

Mara

thanx mara jade for your suggestion.
But in this case i want to print invoice so i need to print directly to the printer insteadly view the report first. if you have other suggestion i will be gratefull

A solution we have implemented for this problem is if the printer itself has a network address.

Add the printer as a local printer to your web server box connected by a Standard TCP/IP port.

With the Add Printer Wizard
1) Select Local Printer
2) Choose to "Create a new port"
3) Select Port Type: "Standard TCP/IP Port"
4) Provide the IP address for the printer
5) Select the appropriate printer driver
6) Give the Printer the desired name, ie. "TESTPRINTER"

This will allow you to send your reports directly to a networked printer without a need to provide the server name from which the printer is accessible by using the standard
Report.PrintOptions.PrinterName = "TESTPRINTER"

It doesn't necessarily allow you to access a printer on another server but it does allow you to send print jobs directly to a networked printer with is typically the desired end result.

Hi, I did a search in Google for this solution and found your posts. You saved me alot of time by trying all those things they suggested. I'm not sure if you figured it out since it was last year but I found the solution. I just started working with Crystal in .NET. Anyway all you have to do is:

You were right in trying to assign it this way.
crpt.PrintOptions.PrinterName = "\\banupriya\hp LaserJet 1300 PCL 6"

It kept giving a problem because it was intrepreted this way:
crpt.PrintOptions.PrinterName = "\banupriyahp LaserJet 1300 PCL 6"

What you have to do is assign it this way:
crpt.PrintOptions.PrinterName = "\\\\banupriya\\hp LaserJet 1300 PCL 6"

Each set of "\\" represents one "\" so since you need 2 "\\" in the beginning you have to initialize it with 4 "\\\\" so it can be intrepreted like this:
crpt.PrintOptions.PrinterName = "\\banupriya\hp LaserJet 1300 PCL 6"

same i am trying from nearly 3 months but i didnt get any solution.
I am printing a file to a network printer from webservice which is running from IIS. When i execute the code directly from Visual Studio it prints but when i execute by putting URL in addressbar ie running through IIS it does not prints. But it prints on local printer.

The second thing is i have given all rights to aspnet user also iwam user.
Printer is shared also have given full control to everyone. Also i hav tried all things mentioned above. As my company is Microsoft gold partner we hav put this case on their helpdesk but i am strange that they are also not able to find a solution on this.
I m fed up now tried everything given all rights to all things where security is define..windows authentication is also enabled for VD and anonymous user is enabled.

Any one knows the correct solution???
