Is an infrared printer still worth getting?

[Dave Britten]

I think it's definitely worth having a printer if you've got any of the supported models. It's especially handy with the 17BII or 19BII running in trace mode so you can have an audit trail of financial calculations, or print out the whole set of TVM variables, for example. It's great with the 42S since you can make use of the printer within programs. And of course it's useful for making hard copies of solver equations or programs (though you'll want to digitize them since thermal paper isn't exactly archival quality).

Personally, I feel like the wired printer for the HP 41 (82143A) is a bit nicer - and quieter - but the IR model gets the job done. It also runs on AA batteries, which are easier to deal with.

Off the top of my head, it works with these models, so if you've got a few of them, it's worth picking one up.

Not sure about the status of the 49G/50G family, but it might work with some of them.

I think it will also work with the 95LX and maybe 100LX/200LX if you install some kind of drivers to support it, but I've never experimented with this.
