Mac Forum / Programming / Mac Programming / November 2004How to determine hardware printer margins in Mac OSX?
Hi, I am porting an application to the Mac that prints. I need to know what margins the printer has, so that I can print right up to that line. In windows I have used GetDeviceCaps to find out the margins of the user's printer. How can I do this on the Mac? I am using realbasic, but posted to the comp.sys.mac.programmer group as well, in case realbasic does not have this capability and I will need to use something from the carbon library.

On Macintosh, you ask the print system for the page rectangle and the paper rectangle. The paper rectangle is the physical size of the paper, and the page is the printable area. The user specifies which printer, or generic, on the Page Setup dialog box. The user is allowed to queue a print job on one printer, then drag it to another printer, and if he does he deserves to get what he gets. Read: <http://developer.apple.com/documentation/Carbon/Reference/Carbon_Spec_Porting/Ca rbon_Printing_Manager.html> and <http://developer.apple.com/documentation/Carbon/Reference/CarbonPrintingManager_ Ref/cpmref_reference/function_group_3.html> Thanks, that was exactly what I needed. Well actually...would you happen to have a code snippet in realbasic that returns the margins in inches (after the user selects the printer in the dialog). > Thanks, that was exactly what I needed. The PrinterSetup class in the Language Reference has an example that shows how to do this (stupid me). I will test it out and see if it returns the hardware margins, or just the page size. > Well actually...would you happen to have a code snippet in realbasic that > returns the margins in inches (after the user selects the printer in the > dialog). > > > Thanks, that was exactly what I needed. |
