This hack still hasn't failed me. First, I do a PDF
that is A5 (i.e., smaller than A4). Then I print it on
a regular A4.

#! /bin/zsh

# This file: http://user.it.uu.se/~embe8573/conf/.zsh/jpeg2pdf

# more: ./gfx
#       ./dump
#       ./x

jpeg2pdf-paper () {
    local paper=$1
    shift
    local pic
    local pdf
    for f in $@; do
        pic=$f
        pdf=${pic:r}-$paper.pdf
        gs -sDEVICE=pdfwrite \
           -sPAPERSIZE=$paper \
           -o $pdf viewjpeg.ps \
           -c "($pic) viewJPEG showpage"
    done
}
jpeg2pdf-a5 () { jpeg2pdf-paper a5 $@ }
jpeg2pdf-a4 () { jpeg2pdf-paper a4 $@ }
jpeg2pdf-a3 () { jpeg2pdf-paper a3 $@ }
alias jpeg2pdf=jpeg2pdf-a4
