So...
This is really weird. I had the topo BeNeLux pro installed as an img file with imdisk. Basecamp informed me each time it booted that this map did not allow printing. Then I downloaded the BeLux pro PC version, which came as an unlocked .gmap file. Installed it into basecamp and noticed I could now print from BOTH maps. I then again removed the PC version .gmap and now Basecamp allows me to print from the old imdisk mounted BeNeLux pro .img map!

Don't know what happened here, but I sure like it!
