PrOpen

Initialize the Printing Manager

#include <PrintTraps.h> Printing Manager

void PrOpen( );

PrOpen opens the printer driver and the printing resource file and

otherwise initializes the Printing Manager.

Returns: none; call PrError for result code.

Notes: Call PrOpen before issuing any other Printing Manager calls and call

PrClose when you are all finished printing. At one time, Apple

recommended that PrOpen be called at the beginning of the application, and

PrClose be called at the end, before returning to the Finder. As more

printer drivers become available, it is important for applications to

consider the presence of other applications and how opening and closing the

printer driver affected them. Apple currently recommends that applications

open and close the printer driver each time the application uses the Print

Manager.

Other managers should be initialized (via InitGraf, InitFonts,

before calling PrOpen.

Before starting to print a document, initialize a TPrint record via

Setup..." request and call PrJobDialog to process a "Print..." request.

To print the document, call PrOpenDoc once and call PrOpenPage at the

start of each page. Use Quickdraw commands such as DrawText and

DrawPicture to send output to the printer. Afterward, you may need to

print a spooled file via PrPicFile.
