Sorry about that, I should have realised (must be slow on the uptake today) but….


I still get the grey area when I print the card.
Do you have any insight into why this should happen?
(see thread “Capturing screen into image”)?


Thanks

Terry

Ink based printers are designed to do this because they can just catch the ink that gets oversprayed, and you can clean/empty the waste ink container periodically. Toner is different because the paper with the toner has to travel through the fuser, and then what doesn't get fused gets picked up in the waste toner bin AFTER the fusing process. The toner that gets left behind on a toner based printer has to have some means of being collected.
