I would like to add regarding ink based printing especially when people are expecting photos to last 20, 30 or more years is to do your home work first. I always find that ink based prints fade after a few years and I suspect that is due to us not keeping them in "archival" conditions, I.e. low humidity and temperature. I have a few 30" prints that are holding up but each of those prints probably cost me like rm100+ printed by professional printers. My take is don't expect RM1.50 prints even for 4R to last without fading

Before i say anything else and other ppl here kecil hati later, I have and continue to be a film photographer and do my make my own hand printed photos. So if anything my views can be a bit biased.
Almost no photos will remain pristine given time but at the end of the day it's a matter of how badly deteriorated it will become. Regarding photo storage look for white papers from Kodak. They have some of the best scientific papers on anything photography. Basically the general rule of thumb is low humidity, no light, low temperature. For printing nothing beats silver halide prints, followed by pigment inks followed by dye inks.
Silver halide (coloured) I am sure no one in Msia does it, the only option is B&W hand prints. They are rated for 1000 years. Pigment ink the only one I know of is Epson's K2 and K3 ink based printers and rated at 100/200 years. Dye based inks (which pretty much means everything else) could be a couple of years to maybe 100. Of course weather those test conditions matches our actual storage conditions or how much deterioration was the measurements made against is up for debate.

there are a lot of reviews and research on this online. End of the day you get for what you pay for. If given a choice I would go for Epson K series printers based on the reviews i have read.
