Unable to print large files

Hi,
I have a difficulty printing some large files.

Error message is :
Printer File
Error writing on LPT1 : for printer (HP Deskjet 815C Series Printer) : This function only valid in Win32 mode.

I can’t figure this message out.

This happens often but not systematically.

PIII 750 MHz Win98SE 512 Mo

Thanks for your help !
