Large Text Files & Quickreport

hi,

how can i print large text files (30.000 lines+ or 1MB+) with
Quickreport.
Now i use QRRichText, but it takes a lot of time to load, but that's not
a problem;
problem is, when i hit preview, it takes a lot of time...and whole page
blinks as
it loads for about 20 minutes, which is unacceptable for a user.

(i use: Pentium 600 MHz, 256 MB ram, Win2000, Delphi 6)

TIA,
Ales
