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,
