Use an unformatted write:
for i=0L, 307199 do begin
s = string(image[i], format='(I1)')
writeu, wlun, s, 13B
endfor
This may not be very fast! In principle, the following should be faster, but
you will find that the explicitly formatted string conversion is limited to
1024 lines.
writeu, wlun, string(image, format='(I1)')+string(13B)
AFAIK, you can't change the line terminator used by PRINTF
