"How do Pictopia prints compare to large format inkjet prints?
Pictopia produces true photographic prints. Since we print on photographic paper exposed by light (LightJet laser enlarger), rather than ink sprayed on paper (Inkjet printer), our prints will look sharper and more realistic. Our LightJet prints at 300 ppi continuous tone, which is comparable to a resolution of 4000 dpi or more with an inkjet. In addition, photographic paper is more archival and durable (less likely to crease or wrinkle) than most inkjet papers."
I think Pictopia is a great lab for conventional laser imaged, silver prints that practices (unlike so many such labs), color management. That said, the statement above is
nonsense unless it was written 7-8 years ago and needs serious updating.
Modern ink jets, certainly those I've had experience with (Epson's with K3 or HDR inks) blow the doors of such chromogenic prints in terms of longevity, color gamut, options for surfaces and I suspect, resolution (that being kind of a nonsense smoke and mirrors, undefined spec).
