Originally posted by Another dyemention I actually didn't even convert it to JPEG first. Is that something I should do?
Not needed in LR, which treats a jpeg and a print as essentially the same thing, a final output from the RAW file and develop process. There is no benefit to exporting a jpeg first, and I would think it could potentially reduce the quality since the compression will throw away data that it does not need.
Different paper reacts quite differently which is why the printer profiles are so important. You might try a different brand. But as noted above without a gray cart your printer is using color ink to simulate the B&W.
Also, do you have LR set to manage color or the printer set to manage color? Or both? If both, that is another potential issue. Color should be managed by one or the other, not both.
And it is sometimes very hard to find the setting in the printer driver to turn that off.
