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.
How (where) do you change from 64 bit back to 32 bit for printing? I can’t find anything to “check” or uncheck as you mentioned.
Bob,
If you are on a Mac, just find the Lightroom application (should be in /Applications) and select it, then do Get Info in File and there is a checkbox there to select 32-bit mode.
wow – you saved me! I just finished Reading Seth Resnik’s book and changed it to 64 bit and went to print and got all those lines! Thanks big time – I had an important project to print!

Thank you very very very much. I went to print in LR2 and had the options crossed off. I googled the solution and your blog was my first hit…and voila, easy fix. Nice to find some easy solutions once in a while. Thanks again.
