Printing Error

dweiser

Running OST v1.14.1 on a Windows server 2012R2
php 7.3
mysql 8.0

When I try to print, I get the following:
Fatal error: Uncaught Mpdf\MpdfException: Temporary files directory "C:\Windows\TEMP" is not writable in C:\DATA\WEBSITES\labnet\support\include\mpdf\vendor\mpdf\mpdf\src\Cache.php:17 Stack trace: #0 C:\DATA\WEBSITES\labnet\support\include\mpdf\vendor\mpdf\mpdf\src\Mpdf.php(983): Mpdf\Cache->construct('C:\Windows\TEMP') #1 C:\DATA\WEBSITES\labnet\support\include\class.pdf.php(76): Mpdf\Mpdf->construct(Array) #2 C:\DATA\WEBSITES\labnet\support\include\class.ticket.php(3504): Ticket2PDF->__construct(Object(Ticket), 'Letter', NULL, NULL) #3 C:\DATA\WEBSITES\labnet\support\scp\tickets.php(503): Ticket->pdfExport('Letter', NULL, NULL) #4 {main} thrown in C:\DATA\WEBSITES\labnet\support\include\mpdf\vendor\mpdf\mpdf\src\Cache.php on line 17

We have given write permission to Everyone, and it still crashes. Any Suggestions?

dweiser Temporary files directory "C:\Windows\TEMP" is not writable

The webserver user reports that it cannot write to: C:\Windows\TEMP.
What user is your webserver running as?

I'm not sure. Is there a way to see that information? (I'm new to this stuff)

It appears to be me, but I'm the administrator.

ntozier

You would have to google the [unknown] and Os that you are running to find out. Then check the permissions on the folder.

dweiser

IIS is running and administrator and has all permissions to the folder. It makes no sense to me.

I tried to export the ticket, and got this:

Does MPDF not run on Windows?

ntozier

Your webserver software (IIS) is not run as the user Administrator. The administrator account having access to something does not mean that your webserver does. IIS runs as IIS_IUSRS.

MPDF runs fine on my Windows IIS setup.

TheDeadGuy

Check the folders have the security entry "ALL APPLICATION PACKAGES" or "ALL RESTRICTED APPLICATION PACKAGES" or "NETWORK SERVICE" or "DOMAIN\IIS_IUSRS".

I'm not as experienced in IIS, but I feel like a there's a high chance "IIS_IUSRS" User does not have full access to places it requires access to.
I may be wrong, i'm mainly looking at a pre-existing setup so.... but hopefully this points you in the right direction.

The IIS_IUSRS should be IIS_IUSRS (WebServerName\IIS_IUSRS) not DOMAIN\IIS_IUSRS
Try adding
users (WebServerName\Users) with Modify access

Hi, I haven't got an issue. I run my webservers on Linux based machines 😁
I'm just curious on whether OP has correct users/permissions set.

Thanks for the additional comment/assistance though.
