I've used a Shooting Chrony F1 and a Pro Chrony that both worked well enough but both were shot and killed at the outdoor range, several years apart.
99% of their use for me is outdoors with centerfire rifles and if I could get them out of direct sunlight they were fine.
These days I've been using an Oehler which is also fine.
Indoors they all have worked well if I set up a "trouble-light" with an incandescent bulb. They will not work at all with fluorescent light.
Pyramid link A lighted chrony for indoor use sounds nice.
I've never had a printer set up with mine, yet.
