By reading TTF/OTF spec again, I found that
checkSumAdjustment slot of `head' table must be recalculated
on generating a Type42 font.  I was copying `head' table
verbatim in the previous code, but it seems that gs and some
printers just ignore that value, and thus processed the code
without error.

Here's the new code.  I eliminated all unnecessary part (no
setpagedevice for A4 or US-LETTER, etc), so an error if
occurred is surely because of the Type42 handling code.  It
just prints cyrillic-iso8859-5 characters in 16x6 form (at
the bottom of a paper).
