I'm using Lightroom 2.5 to print to an HP 130 printer. I'm printing a 4" x 18" file at 300ppi, with the print resolution box unchecked. If I print the photo at 4" x 18", it looks fine. But if I increase the image size by a small amount to 5" x 22", Lightroom prints it at 245ppi, but the output has terrible resolution and visible jaggies. When I ran the same job a few minutes later, I got normal resolution. Could this be a bug?
Thanks,
Chris Morgan
