I did. But they probably just replaced the setup cartridges in the backpacks with normal ones. Sadly there are only so many manufacturers who make good quality backpack-sized printers.
It depends on what you need, I've been a fan of Brother for years and their thermal printers actually have a full sized printer that fits in a backpack (it's basically a rollthrough printer).
The issue is putting a pack of thermal paper and not forgetting it.
I hope you diffused the information and that this printer brand is now known and banned in every emergency service as unsuitable.
