Safe Printing

P: n/a
I am trying to find the definition of "Safe Printing" and cannot find out
exactly what this entitles. The reason is that I am trying to print
contents from a single textbox to no avail using the PrintDialog control
under a security setting with only SafePrinting allowed.

I have attached a sample project that I am using to try to accomplish this.
The print dialog appears, but when I press the Print button, I get an
exception (at the end of this message). Any ideas how I can make this work?

Thanks,
Jody

The code in question is as follows:

With dlgPrintSettings

If Not (.ShowDialog() = DialogResult.Cancel) Then

Try

TextBox1.AppendText("Printing ..." & ControlChars.CrLf)

..Document.Print()

TextBox1.AppendText("Print Successful")

Catch ex As Exception

Debug.WriteLine(ex.ToString)

'MsgBox(ex.ToString)

End Try

End If

End With

The security exception is thrown within the following line:

If Not (.ShowDialog() = DialogResult.Cancel) Then

after you click the PRINT button. The line below it never gets called:

TextBox1.AppendText("Printing ..." & ControlChars.CrLf)

Thanks,
Jody

this.
The print dialog appears, but when I press the Print button, I get an
exception (at the end of this message). Any ideas how I can make this
work?

Thanks,
Jody

Let me admend this, you'll also need safe printing. Just to display the
dialog box you're going to need unrestricted UIPermission, then to perform
the printing you'll need the safe printing permission. Was able to run your
app to completion with safe printing permission. You may not need all the
other permissions I came up with, you might try experimenting.

The code in question is as follows:

With dlgPrintSettings

If Not (.ShowDialog() = DialogResult.Cancel) Then

Try

TextBox1.AppendText("Printing ..." & ControlChars.CrLf)

.Document.Print()

TextBox1.AppendText("Print Successful")

Catch ex As Exception

Debug.WriteLine(ex.ToString)

'MsgBox(ex.ToString)

End Try

End If

End With

The security exception is thrown within the following line:

If Not (.ShowDialog() = DialogResult.Cancel) Then

after you click the PRINT button. The line below it never gets called:

TextBox1.AppendText("Printing ..." & ControlChars.CrLf)

The only way I can get an Internet permission set equivalent to work is to
up the printing permissions to all. Doesn't work with safe.

I am still having difficulty in getting this to work. I have attached an
updated sample project with what I am trying to accomplish.

The project will be run over the Internet Zone with the default security
settings which have limited UIPermissions and SafePrinting. The permissions that I have enforced on the project are listed below this message. One
change that I had to do was to move the UIPermission from Minimal to
Optional in order for the application to run over the Internet Zone.

If somebody is able to get printing working with the permissions I have
described, could you please provide some sample code as to how it was done? I am not sure if I am just missing something small or if I am completely
off-base with this. Having the print dialog is not a requirement for this
if it violates the default security settings for the Internet Zone.

Permissions on the Assembly:
------------------------------
minimal permission set:
<PermissionSet class="System.Security.PermissionSet"
version="1">
<IPermission class="System.Security.Permissions.SecurityPermiss ion,
mscorlib, Version=1.0.5000.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089"

<IPermission class="System.Drawing.Printing.PrintingPermission,
System.Drawing, Version=1.0.5000.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a"
version="1"
Level="SafePrinting"/>
</PermissionSet>

optional permission set:
<PermissionSet class="System.Security.PermissionSet"
version="1">
<IPermission class="System.Security.Permissions.UIPermission, mscorlib,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

P: n/a
According to the documentation, the Internet Zone allows for Safe Printing.
Exactly what is "Safe Printing"? Is the documentation incorrect? Or am I
interpreting this incorrectly in assuming that I should be able to send
information to the printer with SafePrinting set?

With my sample application, I set the PrintingPermission to AllPrinting from
SafePrinting which worked if run locally, but still does not work when run
through the Internet Zone (launched from a web server). Adjusting the
permissions on the Internet Zone itself to allow for AllPrinting vs
SafePrinting is not an option for us.

Is printing even possible from a "No Touch Deployment" appliction run over
the web with the default settings for the Internet Zone (which has
SafePrinting and not AllPrinting)? If so, is there documentation or sample
code that I can run to see how this is done?

Thanks,
Jody

The only way I can get an Internet permission set equivalent to work is to
up the printing permissions to all. Doesn't work with safe.

I am still having difficulty in getting this to work. I have attached an
updated sample project with what I am trying to accomplish.

The project will be run over the Internet Zone with the default security
settings which have limited UIPermissions and SafePrinting. The permissions
that I have enforced on the project are listed below this message. One
change that I had to do was to move the UIPermission from Minimal to
Optional in order for the application to run over the Internet Zone.

If somebody is able to get printing working with the permissions I have
described, could you please provide some sample code as to how it was

done?
I am not sure if I am just missing something small or if I am completely
off-base with this. Having the print dialog is not a requirement for this if it violates the default security settings for the Internet Zone.

Let me admend this, you'll also need safe printing. Just to display the dialog box you're going to need unrestricted UIPermission, then to perform the printing you'll need the safe printing permission. Was able to run your
app to completion with safe printing permission. You may not need all the other permissions I came up with, you might try experimenting.

P: n/a
You'll notice a "send comments on this topic" at the bottom of the page for
PrintDocument.Print (the one that states safe printing is the required
permission). I clicked on that and sent in a comment about safe printing
not working. Should get to the writer and should result in a bug being
filed unless you and I are missing something. You could do the same if you
would like to hear back directly. I've checked for bugs and don't see any
filed for this.
