I'd be curious to know whether your color laser comes equipped for PostScript printing; and if so, whether it's true PostScript or "emulated !PS."
Color laser printers have been dropping in price at a rather spectacular rate during the last couple of years. At present the best I've heard of are 4-color, and although the color is pretty good it's not quite up to that of good 4-color inkjets. Even "microground" toner still has a visible grain on the paper, which isn't a problem for most stuff but could be a little less than you'd want for something critical.
I'd expect print fading to be less for a laser than for many popular inkjets, but haven't seen any confirmation of that; and fade resistant inks are becoming more available.
I've seen a few color lasers advertised that are almost as cheap as typical ink jets were a couple of years ago. I haven't seen reliable reports on print quality or per page costs for the cheaper ones. The ones I looked at some time ago were a bit $$cary when you looked at replacing 4 toner cartridges at $60 or more each, but probably the actual printing cost would be comparable - maybe less - than for inkjet.
Some of the newer low cost color inkjets also appear to use somewhat smaller toner cartridges, so I'd expect a bit lower per cartridge prices, but with correspondingly fewer pages per cartridge.
A likely reason for the sparse availability of PostScript in inkjets is that nearly all inkjet printers are color printers, and would be expected to see heavy use of graphics. PostScript can be incredibly slow when rendering pages with significant amounts of graphic content. Useful !PS handling also requires large amounts of memory in the printer - at least compared to other "printer languages," and the average home/small office user probably doesn't have a real need for the !PS anyway and wouldn't know what to use it for.
You can get a "software RIP" for almost any printer, that will let you print directly from PostScript scripts, but the last one I got, several years ago, (from the big name, Birmy) was $650 - for a $300 printer. The RIP software may be a bit cheaper now. The printers certainly are. But I haven't looked at software RIP programs recently.
It works better if the RIP is built into the printer, but many "printers with built in !PS" actually only "emulate" true PostScript printing by doing the RIP in the driver, and sending some other language to the printer. That works for some things, but it prevents you from doing a few things that only real PostScript can do.
And so far as I know, you still can't get a color inkjet printer that's PostScript capable at anything approaching a "consumer price" - in the home or small office user range.
