pdf_findfont: error?

[angel duran]

I'm new to php and i'm trying to print a table from my database with
pdflib, but i always get this error:
Fatal error: PDFlib error: [2516] PDF_findfont: Metrics data for font
'times-roman' not found in C:\apachefriend s\xampp\htdocs\ pdftest.php
on line 10

this is the code
<?php
$pdf = pdf_new();
pdf_open_file($ pdf, "test.pdf") ;
pdf_set_info($p df, "Author", "Javier Tacon");
pdf_set_info($p df, "Title", "Test for PHP wrapper of PDFlib 2.0");
pdf_set_info($p df, "Creator", "See Author");
pdf_set_info($p df, "Subject", "Testing");
pdf_begin_page( $pdf, 595, 842);
pdf_add_outline ($pdf, "Page 1");
$font = pdf_findfont($p df, "times-roman", "host", 1);
pdf_setfont($pd f, $font, 10);
pdf_set_value($ pdf, "textrendering" , 1);
pdf_show_xy($pd f, "Times Roman outlined", 50, 750);
pdf_moveto($pdf , 50, 740);
pdf_lineto($pdf , 330, 740);
pdf_stroke($pdf );
pdf_end_page($p df);
pdf_close($pdf) ;
pdf_delete($pdf );
echo "<A HREF=getpdf.php >finished</A>";
?>

any suggestions?
