Need help with bold face and HP PCL

[Zoong PHAM]

I have a text file that I need to convert to PDF.
I use a2ps to convert the file to PostScript then use ps2pdf to
convert to PDF.
So far the conversion is working.

A small problem is the text file has some lines start with (s3B^M 
and end with (s0B. These 2 are the HP PCL sequences for turn on and 
turn off bolding, respectively.
I need to have the lines in bold face in PDF.

The result PostScript and PDF files don't have the lines in bold face.

I played with style sheet (followed the section 7.7 A Tutorial 
on Style sheets of the Manual) without success.
And the PostScript and PDF files still don't have the lines in bold 
face. The HP PCL sequences are printed literally.

Here is my style sheet:
   alphadev> cat /usr/local/share/a2ps/sheets/iba.ssh 
   # This is a style sheets for  report
   # that handle bold strings.
   #
   style iba is
   written by "Zoong PHAM (MHAC) <address@hidden>"
   version is 1.0
   requires a2ps 4.9.5
   
   documentation is
      "Second level of high lighting covers emails."
      "high lighting (bold)  report strings between ^[(s3B^M and ^[(s0B 
markers."
   end documentation
   
   sequences are
     "(s3B" Plain Label_strong "(s0B" Plain
   end sequences
   
   sequences are
     "ZOONGSTART" Plain Label_strong "ZOONGEND" Plain
   end sequences
   

   end style

I carefully edited the above file to make sure ^[ is escape character.

And here is the entry in my sheets.map file
   alphadev> grep -i iba /usr/local/share/a2ps/sheets/sheets.map
   #  reports
   *iba*                iba


And here is a sample of my input text file:
