RE: What about php 5.3 and printers or PHP_PRINTER.DLL ?

I will take a look at FPDF, but having the users have to first open a
PDF document and then print that creates it's own set of problems. We
have a extremely complex and integrated Intranet site that does all
kinds of reporting, and the area that it completely sucks is when it
comes to printing. Not having simple control over things like Landscape
versus Portrait or better page breaking drives us crazy.

I already mentioned the reason of failure. It is strange that
OpenPrinter function is passing but DocumentProperties is failing.
Ideally once OpenPrinter passes, everything should go through. And the
worst thing is that this is an abandoned package. I don't see any
maintainer for it. Why don't use something else like FPDF or something
else which is generally supported?

Thanks,
Don.

Nope. I have an account called Test. It is not an Administrator account
(local or domain) and it can print to \\server05\Auth, but it fails here
too.

Hi,

I did some test on Windows7 as well as Windows Server 2008. I used
fastcgi.impersonate=1 in both the cases. On Windows 7 everything is
fine. From Windows Server 2008 I am getting below error:

Fatal error: Out of memory (allocated 524288) (tried to allocate
4294967295 bytes) in C:\inetpub\wwwroot\phptest\print.php on line 2

The test file 'print.php' is a simple PHP file where I am making one
call to printer_open.

So went and debugged the code. In the function printer_open
implementation, we make call to OpenPrinter and later to
DocumentProperties. For some reason (I haven't figured it yet),
OpenPrinter call is success whereas DocumentProperties fails and returns
a negative number. Now look at the code below:

if (OpenPrinter(resource->name, &resource->handle, NULL) != 0) {
 
 		resource->pi2 = (PRINTER_INFO_2
*)emalloc(sizeof(PRINTER_INFO_2));
 
 		resource->pi2->pDevMode = (DEVMODE
*)emalloc(DocumentProperties(NULL, NULL, resource->name, NULL, NULL,
0));
 
 		if (DocumentProperties(NULL, resource->handle,
resource->name, resource->pi2->pDevMode, NULL, DM_OUT_BUFFER) == IDOK) {

Above the code tries to use Zend allocator to allocate memory assuming
DocumentProperties returned a valid value (here the actual size).
However DocumentProperties returned a negative value meaning failure and
I believe this value is treated as unsigned integer leading to a huge
value and thus the above message.

Regarding why DocumentProperties fails, I am not very sure. And this
happens on Win2k3 too. Look at the bug reported at
http://pecl.php.net/bugs/bug.php?id=12293 long time back.

Keith, you can try accessing the printer under a normal account and
which is not part of administrator group and see if this helps. Ensure
that the normal user has permission to access the printer.

Thanks,
Don.

Well, I'm on Server 2003, and I still cannot print. It only works with
impersonate turned off, and that is not a solution, as I need to connect
to remote files.

hi,

It works just fine here, did you install the print server?

Cheers,
