Please ignore my previous e-mail, may too much work this week .... Sorry.

the following sentence imply SHRINK_AMOUNT conversion from Points to
decipoints,
as it is in pcl.c, barcode-0.98.

 ----------snip------------------------------------------------------

fprintf(f, "%c*c%.0fH", 27, ((j*scalef ) - SHRINK_AMOUNT) * 10.0);

 ----------snip------------------------------------------------------

I will review pcl.c the next week.
