Gremlin in QR304Std D403

Hi All;

I am looking for help with a printer related error when I open one of
my programs in Delphi 4 IDE.

I am getting this error message sequence when I try to open the
program's
dpr file.

'Error reading form'
'Printer selected is not valid'
'Error creating form'

The program is written in D4.03 with QR3.04 std. using W95B.
The default printer is HP670C. If I change the default printer to
HP500 the problem disappears.

I have deleted the projects dsk and dof files and reloaded the HP
driver.

This is not a new hardware system setup, just the error is new.

TIA
Bill
