Sandboxie Support

I looked for a solution to print outside the sandbox with sandboxed Firefox, but the solution that I saw in the forum which involves adding an entry in the sandboxie.ini file and in Firefox settings did not help.

Every time I try to print something in Firefox I see a message box

SBIE1319 Blocked spooler print to file, [11836] firefox.exe, \Device\HarddiskVolume2\Windows\Temp\HPVB3DE.tmp.vdf
SBIE1320 To allow print spooler to write outside the sandbox for this process, please double-click on this message line

Unfortunately, double-clicking on the line does not solve the problem.

I take this opportunity to wish all Sandboxie users, developers and supporters a Happy New Year!

Please add the following line to the sandboxie.ini: Happy New Year!

Thank you for the suggestion. I tried it but it still doesn't work. I have to delete print files from the spool as none are printed.

See if adding this to the configuration for your sandbox will allow printing:

AllowSpoolerPrintToFile=y

Strange! Did you stop all sandboxes and reload the configuration before printing? Or did you get another message box?

No luck with printing. I added the AllowSpoolerPrintToFile=y to my sandbox, but without any success.
I stopped all sandboxes and reloaded the configuration before printing. I got the message box again.
The files to be printed end up in the print spooler, and I have to clear them by running a batch file as Administrator (net stop spooler
del %systemroot%\System32\spool\printers\* /Q /F /S
net start spooler), otherwise I cannot print any other files.

EDIT: I found the following.
By disabling the preview of jobs to be printed, I can print from Firefox even though the message box comes up.
I suspect that the preview feature must be a separate program running for my printer (HP model). I'll try and find out what it is and add it to the Sandboxie as an allowed program.

By the way, what is the effect on security by changing the setting in Firefox (security.sandbox.content.level) from 3 to 2?

Was it exactly the same text in the message box? Or another path in the SBIE1319 line? Sometimes you have to open more than one path.

The message is

SBIE1319 Blocked spooler print to file, [4604] firefox.exe, \Device\HarddiskVolume2\Windows\Temp\HPVC68D.tmp.vdf
SBIE1320 To allow print spooler to write outside the sandbox for this process, please double-click on this message line

Based on this which path should I open?

It's the same path as in my first reply: viewtopic.php?p=131638#p131625.

Did you add the line under the correct section of sandboxie.ini (= below the name of the Sandbox using for Firefox)?

I checked the location in sandboxie.ini and the entry is in the sandbox that I use to run Firefox.
What may be odd is that the printing proceeds without me doing anything even though the dialog asks me to double click on the specific line in order to allow printing.

Strange! Sorry, I don't know why your Sandboxie installation neither accepts the OpenFilePath nor the AllowSpoolerPrintToFile.

Thank you for your assistance anyway. I'll try it again when I have time with a new sandbox or even a new Firefox profile.
