What's so bad about inkjet? The ink is going to be cheap since it's not proprietary cartridges and the clogging issue is very overblown IMO. I've had one crappy cheap Canon and one crappy cheap HP inkjet and neither one dried up when left alone for several months. Took the HP being unused for 5+ years on what was still the original ink cartridges for it to stop printing.
This being open source hardware means if it DOES get clogged, the parts will likely be cheap, and it not having ultra tight tolerance nozzles AFAIK means clogs are less likely to happen.
I'm likely not buying/building one because I just don't need to print things that often anymore (hence the HP sitting around for years between prints), but I don't foresee inkjet being a deciding factor in THIS case. It would be if I was getting a proprietary printer.
