I thought you just wanted the image.

Instead of "pdfimages" use "pdftoppm" instead (also from xpdf or 
poppler-utils).

Why not print direct from the PDF then? Converting a PDF to JPEG doesn't 
seem correct for printing since you then (usually) need to convert the 
JPEG back to a printable format.
