PrinterVectorOutput different values for Win/OS-X

[fromVB]

Why does VectorOutputWidth and VectorOutputHeight give different results for the same printer having the same paper settings for #PB_Unit_Pixel at 600dpi?

Code: Select all

On Windows:
PrinterPageWidth() = 4760
PrinterPageHeight() = 6814

VectorOutputWidth() = 4771
VectorOutputHeight() = 6803

On OS-X:
PrinterPageWidth() = 2380
PrinterPageHeight() = 3368

VectorOutputWidth() = 2479
VectorOutputHeight() = 3508

I know it looks like the DPI settings but it shows 600dpi for both.

Plus when using #PB_Unit_Millimeter I get this:

Code: Select all

On Windows:
VectorOutputWidth() = 202
VectorOutputHeight() = 288

On OS-X:
VectorOutputWidth() = 209.902
VectorOutputHeight() = 297.039

Mac shows full paper size and not just the printable area.

Is this correct?

If the first set of results you show on OSX really is with a 600 dpi setting then that must go down as a bug. I'd report that if I were you.

The second issue (strange that more accurate results are given in mm) is obviously, at best, an inconsistency. No harm in reporting that as well as, in the interests of cross-platform compatibility, we'd like all platforms to report identical results where possible.

PrinterPageWidth() = 4760
PrinterPageHeight() = 6814

VectorOutputWidth() = 4771
VectorOutputHeight() = 6803

The Windows results are not accurate if the DPI is exactly 600 (is it 600dpi for Height also?).
.... and the VectorOutputWidth() should not be greater than PrinterPageWidth()
Smells like a bug

It could have to do with a retina display where there's a difference between physical and logical pixels.

Ah... keep forgetting about the retina displays.

Would the retina display make a difference with the printer resolution though?

Yes they are both 600dpi.

If the settings are correct. There is no default settings as with Windows, but the default print settings being used show the dpi as 600. I could only check it through TextEdit.

fromVB, a new post in the Bugs section should be opened, detailing the faults found.
