Lightroom 2 64-bit Printing

I was doing some printing in Lightroom recently and was struggling. The prints were coming out really badly, and when looking for the quality controls for the Canon S900 I couldn’t find any of the normal settings. This is what it should look like, with options for the type of printing.


But instead I was getting this, with a big crossed out option and an incompatibility over architecture”.


I was pretty confused why this wasn’t working and figured I needed to reinstall my drivers, but didn’t want to restart at that point so left it. I kept noodling this over and that word architecture” was bugging me. Then it hit me!

I’ve posted before about how great Lightroom is in 64-bit mode. It dawned on me that I was running a 64-bit architecture” and the printer driver was probably only 32-bit. I checked the box for Lightroom to run in 32-bit mode and launched it again and the printer settings worked great! It sure would be nice if the error message just said this doesn’t work in 64-bit mode”.

Lesson learned! Run Lightroom in 64-bit, unless you want to print, then restart in 32-bit. If anyone knows what printers have 64-bit driver support it would be great to have a list.
