Sub Articulo 43.2

I did try your suggestion.  First, I looked at the font info in my
AcroRead and here's the list:
  CMSSBX10 Type1 Custom   Embeddes Subset Type 1
  CMSS10   Type1 Custom   Embeddes Subset Type 1
  CMTT10   Type1 Custom   Embeddes Subset Type 1
  CMR10    Type1 Custom   Embeddes Subset Type 1
  CMMI10   Type1 Custom   Embeddes Subset Type 1
  CMSY10   Type1 Custom   Embeddes Subset Type 1
  CMTI10   Type1 Custom   Embeddes Subset Type 1
  CMSSI10  Type1 Custom   Embeddes Subset Type 1
  CMCSC10  Type1 Custom   Embeddes Subset Type 1
  CMU10    Type1 Custom   Embeddes Subset Type 1
  CMMI7    Type1 Custom   Embeddes Subset Type 1
  CMR7     Type1 Custom   Embeddes Subset Type 1
  CMSY7    Type1 Custom   Embeddes Subset Type 1
  LASY10   Type1 Built-in Embeddes Subset Type 1
  CMEX10   Type1 Custom   Embeddes Subset Type 1
Then I printed on PS printer (level 2) and everything came out perfectly.  
>From what you're telling me, perhaps you don't have all the CM/LA
Type1 fonts installed.  Make sure your psfonts.map and related map
files are configured correctly. It's not looking like a FoilTeX
problem but dvips or pdflatex configuration problem.  Like I said, I
don't what FoilTeX could be doing different from plain LaTeX because
the font names are identical, the only difference is the font sizes
and that shouldn't matter to Type1 font.
