| Summary | 0027728: Printing on Mac OS X with 72 dpi only | ||||
| Description | Printing with Lazarus on Mac OS X (Carbon widgetset) is supported with a resolution of 72 dpi only. Regardless of the printer's capabilities the following values are always identical. Printer.XDPI=72 Printer.YDPI=72 Therefore, Mac OS X cannot take advantage of the printer's support for high resolution printing. | ||||
| Steps To Reproduce | Every attempt to print delivers the same result. | ||||
| Additional Information | See the following discussions on the forum: http://forum.lazarus.freepascal.org/index.php/topic,14641.0.html and http://forum.lazarus.freepascal.org/index.php/topic,27849 | ||||

A first step for improving would be to rewrite the TCarbonPrinter.GetOutputResolution method as: function TCarbonPrinter.GetOutputResolution: PMResolution; var res: OSStatus; Major, Minor, Bugfix: SInt32; theError: SInt16; begin theError := Gestalt(gestaltSystemVersionMajor, Major); if theError <> 0 then Major := 0; theError := Gestalt(gestaltSystemVersionMinor, Minor); if theError <> 0 then Minor := 0; if (Major < 10) or (Minor < 5) then res := noErr+1; else res := PMPrinterGetOutputResolution(GetCurrentPrinter, PrintSettings, Result{%H-}); if res<>noErr then begin Result.vRes:=72; Result.hRes:=72; end; end; However, it will not solve any problem. On some machines, still a resolution of 72 dpi is returned, although the printer has 600 or 1200 dpi. |
