print(filename.png,'-SxReolution,yResolution') is producing unexpected and (I presume) incorrect results. 

Specifically on my system the [xResolution,yResolution] provided to print() is resulting in output files with an actual resolution of 1.5*[xResolution,yResolution].  This is not what I expect nor what Octave has done up until 9.2.0.

Here are two specific examples:

print(filename.png,'-S2560,1440") is producing filename.png with resolution 3840x2160.

print(filename.png,'-S1920,1080') is producing filename.png with resolution 2880x1620.

etc.

Here are the details of system I have verified this issue on:

Octave 9.2 on Windows 10 (ver. 22H2, build 19045.4598, "Experience" 1000.19060.1000.0) with the Octave 9.2 installer (octave-9.2.0-w64-installer.exe) downloaded from gnu.org/download

4K monitor with Windows Display Settings set to:

Change the size of text, apps, and other items = 150% (Recommended)
Display resolution = 3840x2160
Display orientation = Landscape
