I need help with changing the default "style" for printing on a imagewriter.
My application does alot of circle drawing which I would naturally like to remain
circles when printed...the laserwriter does this just fine, however I ALWAYS need
to set TALL ADJUSTED in the sytle dialog in order for circles to come out correct
on an Imagewriter! Since my application depends on circles being circles I want
TALL ADJUSTED to be the default style when using an imagewriter. I know how to
sense if an imagewriter is the printer of choice, but cannot find the right location
to poke to set TALL ADJUSTED. Inside Mac is extreamly vague on how to print and says
squat on TALL ADJUSTED. Anyone been here before???
Thanks in advance,

PS: below is the (trimmed) code I am running:
procedure Print;
begin
PrOpen;
hPrint := THPrint(NewHandle(SizeOf(TPrint)));
PrintDefault(hPrint);
{****************************************************************}
{**** CHANGE IMAGEWRITER DEFAULT STYLE TO TALL ADJUSTED HERE ****}
{****************************************************************}
PRBool := PrStlDialog(hPrint);
PRBool := PrJobDialog(hPrint);
myPrPort := PrOpenDoc(hPrint,NIL,NIL); {open printing grafPort}
if PrError = noErr then
begin
PrOpenPage(myPrPort,NIL); {start new page}
{**** QUICKDRAW STUFF HERE ****}
PrClosePage(myPrPort);
end;
PrCloseDoc(myPrPort);
PrPicFile(hPrint,NIL,NIL,NIL,prStatus);
end;

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. Earle R. Horton

You should be able to fetch the available resolutions, then set whichever one corresponds to having tall-adjusted on (144x144?, 72x72??) if it is available. With a little care, it might even be possible to do this in such a way that you don't have to special-case the Imagewriter. --Pete Poorman pwp@shamash.cdc.com

You don't have to know it's an ImageWriter at all, just examine the available combinations of horizontal and vertical resolution and pick one where they're equal. Your code will then work on all printer drivers that support PrGeneral, which includes all current Apple printer drivers. David Casseres Exclaimer: Hey!
