I don't know what a UV printer is. :)

We were using fixed-head printers that we found at the bottom of a deep rabbit hole. The work moved through the machine while the printy-bits remained stationary. We were doing this with HP-style monochromatic carts that came loaded with high-solids "ink" (closer to paint, really) that used opaque white pigment.

Unlike Epson's ecosystem, HP carts most-commonly come as assemblies, with a new print head included in the same disposable cartridge as the ink is. The only connection between the carts and the rest of the printer is electrical; there's no plumbing or functional fluids that are external to the carts.

This self-contained nature means that when ink runs out or heads gets clogged, replacement of everything involved with fluids is fast and easy. Production can continue immediately.

It's not problematic at all...other than being expensive. :)
