I just wanted to clarify a few things i may have left out in my orginial post. I am using Zend Framework 1.0.3. Also, here is the code I'm using to try to generate the PDF.
PHP Code:
// Create new PDF
$pdf = new Zend_Pdf();
// Add new page to the document
$page = $pdf->newPage(Zend_Pdf_Page::SIZE_LETTER);
$pdf->pages[] = $page;
//set font
$font = Zend_Pdf_Font::fontWithPath('/path/to/TimesNewRoman.ttf');
$page->setFont($font, 32);
$page->drawText('Hello world!', 100, 100);
$pdfData = $pdf->render();
//store a date stamp and use it in the file name of the pdf when the report outputs to the browser
$date_stamp = date("Y-m-d_g-i_a");
header("Content-type: application/x-pdf");
header("Content-Disposition: inline; filename=PurgeReport_$date_stamp.pdf");
echo $pdfData;
