Description:

Hallo,
I have developed a Intranet php application for the document press on a local printer, these documents are in a particular format  W=297 x L=1000 milimeter. The problem happens at the moment of the press, the press maximum is  width of 210 milimeter that is of one A4 standard (210x297 milimeter). I have tried this code with various local printer(plotter, laser, inkjet...) and various drivers settings but the result is always the same one, it prints to the maximum 210mm and the rest does not come printed.
It seems that parameters CUSTOM do not come accepted.
Other documents in A4/A5 format are printed correctly. 
Thanks! 
NIK

Reproduce code:
---------------
...
$handle = printer_open("HPDesignJet500"); //Plotter A0
        printer_set_option($handle, PRINTER_PAPER_FORMAT, PRINTER_FORMAT_CUSTOM);
        printer_set_option($handle, PRINTER_PAPER_LENGTH, 1000);
        printer_set_option($handle, PRINTER_PAPER_WIDTH,  297);
        printer_start_doc($handle, $this->array_quadro["cod_disegno"] );
        printer_start_page($handle);

ecc ...

Expected result:
----------------
prints document 297x1000 milimeter

Actual result:
--------------
prints document 297x210 milimeter
