Problems printing using Adobe PDF Converter in Microsoft Powerpoint

I am trying to print a Microsoft Powerpoint (365) presentation to PDF using Adobe PDF Converter.  I'm using the exact settings I've always used and the presentation is not larger than any others I've printed to PDF in the past.  Here's the exact issue:

 

When I print to Adobe PDF, I go into settings and set it for press quality, I use a custom paper size (one I've used for years), and set the dpi to 3600.  When I do this, I get a printer error message saying I need to check the printer installation, etc.  It converts only 11 pages of the 23 every time I try.

 

When I adjust the setting to 2400 dpi, the printing works.  Only problem with that is the quality is markedly lower and I can't use it for what I need (I have several graphics).

 

I've had much larger presentation with even more graphics that I've printed using these settings without issue in the past.  Anyone have any ideas?

 

What I've done:

Restarted computer

Updated Office 365

Repaired Adobe installation

Removed Adobe PDF Printer from Microsoft and re-added

 

I appreciate any help.

Are you sure about those DPI settings? 3600 is obserdly high, 2400 DPI is also.

 

Generally, from a laser write, settings at 300 DPI are just fine and if printing from an inkjet, 180 DPI is fine.

This isn't for physical printing, it's for printing to PDF for presentations which are usually shown on a large screen.  If I convert at anything lower than 3600, the images are clearly degraded.

Hi Jim,

 

I think I'm getting a better handle on what you're trying to do. There is a big big difference between 3600ppi and a projector's potential. For screen presentations, the usual limit is the potential range of the number of pixels (earlier it was the "wide," than later the "high," now the multiplication, aka 4K) that the digital projector can project.

 

In the early days of digital projectors, it was 640 pixels wide. You could have an image that was 10,000 pixels wide but all that could be projected was 640 pixels. (the downside is that the image that is 10,000 pixels wide has a ginormous storage issue.) Then later it was 1040 potential.

 

I just looked and the average high end projector is shown as 1080 which is the height value and a width value of 1920 pixels wide. That means that you could have an image that is 1920 x 1080 pixels wide and it would show in wonderful clarity.

 

But the thing I can't understand is if you have the PP done, how does that look when running through the digital projector? Why convert it to PDF? And if it looks "degraded" from the PP, Acrobat cannot upsample the image to a larger resolution, it just can't.

 

I can recommend some software that does an amazing job of upsampling images (Topaz's Gigapixel), but Acrobat cannot do that. Photoshop does it to some degree (but not as well as Topaz can).

 

Is there anything else you haven't told me that you're trying to do here?
