Thanks to the quick responses.  Here is the solution.

Who gave me this:
You need to add another "symbol" in your printcap file for the printer
in question. The symbol is "mx" and needs to be set to 0 (zero) to allow
an unlimited file size.  The default is around 8 MB (or 1000 x blocksize
(8K)).  Here is a sample from my printcap file:
     lp0|0|OptraS1650|odin01:\
      :lf=/usr/adm/lp0err:\
      :lp=:\
      :mx#0:\
      :rm=139.48.40.239:\
      :rp=139.48.40.239:\
      :sd=/usr/spool/lpd0:\
      :sh:

You can to include an entries  mx#0 in queue  printcap file.
Example: man printcap
 mx     num    1000             Maximum file size (in BUFSIZ blocks). Zero
= unlimited.
