Dmitry, can you print your filled-form PDF when opening it in a PDF viewer (evince, some KDE viewer, ...) set fit-to-page in the printing options in the print dialog and print? The viewers usually re-generate the PDF in a simpler way with the interactive forms replaced by static PDF content and send that to the printing subsystem.

ps2pdf PDFForm3.pdf - | lpr -o fit-to-page
ps2pdf runs your PDF through Ghostscript, which also re-generates it in a static form.
