Digital BW, The Print

Many thanks for the many suggestions to fix my utterly-hosed 2200.
I THINK the problem came after I upgraded to Panther and installed
QTR before getting my Epson ducks in a row.  Fixing it involved
deleting all the Epson drivers, running permission repair (under
Applications->Utilities), and then re-installing the Epson drivers
(downloading the latest one from their website).

I'm now ready to re-install QTR, the latest 2.1 one.  When I added
the Epson in Printer Setup Utility, I did the trick of adding two
versions, with the MK and PK cartridges installed.  

Question: does it make sense to do the same trick when adding the
QTR printers ?  And how does this interact with the various profiles
that came with the QTR 2.1 download ?  Some of them seem to be
prefixed 'UCpk' or 'UCmk', and some just 'UC'.  Also, if I get the
UT inksets, do I need to add yet another QTR printer, or simply
load the right cartridges and use one of the appropriate profiles ?
(It seems like the printer is doing too much thinking for us; I'd
rather be responsible for making sure the ink-load and profile
make sense together !).

Thanks, John
