Paul,
You might try using the LJIII drivers, just to see if it helps.
>I have a client that has a Compaq 2000 Desktop computer. Whenever I start spooling VFP 5.0 jobs to a HP LaserJet 4si, a Windows 95 error message pops ups "Error writing to LPT1". This only happens when I spool **more than** 10 print jobs at once. Also, this is a local printer--no network is involved.
