Digital BW, The Print

In modern printers (2200 and subsequent), this Forum's complaints
about heads, banding, and system failures almost always involve
non-OEM inks instead of Epson's encapsulated pigments. You can prove
that for yourself by browsing posts. 

The real arguments for non-OEM seem to be short-term savings (until
system failures)and, for those who insist, non-bronzing glossies. 

It doesn't seem to be a tone issue...QTRgui and other excellent
approaches and applications provide fine B&W tone control, maximum
Dmax and true grays with OEM.   

Many of us simply have more fun swimming upstream: A minority are
Macintosh or Linux users. I still shoot film. 

What justifies the grief with non-OEM inks in modern printers, rather
than the probably-more-archival (per Wilhelm)OEM pigments?
