It is unwise to try to poke fields in the print record.  A safer
technique is to print something using the style you want, and then
save the print record you used as the default.  Then, when you create
a new print record, skip the PrintDefault, fill in the whole print
record with your saved copy, then pass it to PrValidate.  If
PrValidate returns FALSE, then everything should be just fine.

I am sceptical about your claim of being able to detect when an
ImageWriter is installed.  There are a lot of third party drivers out
there, and it is just possible that one of them would look like an
ImageWriter to your application.  If you use the technique I suggest,
and PrValidate returns TRUE, then it might be an indication that the
printer is not an ImageWriter after all, and you might want to go for
a PrintDefault setup.

The Print Manager should allow users to determine what the default
printing style should be.  I sure hope they put this in the System 7.0
print architecture.
