It's nothing to do with your printer driver. Here's is Microsoft's page on how to increase the export resolution by editing the Windows registry: How to export high-resolution (high-dpi) slides from PowerPoint
How to output 600 dpi files in Powerpoint
I am having trouble outputting high resolution files (e.g. 600-1000 dpi) above 300 dpi in PowerPoint.
Please let me know what I should do.

Thank you very much for your reply.
After reading these instructions, I changed the resolution to 300 dpi, but was wondering if it is possible to set a resolution higher than 300 dpi.
I will try changing it to 600dpi as in the instructions.
Sincerly,

That should be entirely dependent on your printer driver.
Have you contacted support for your printer? -
