Digital BW, The Print

Good Afternoon,

I am new here so if  this needs to be addressed in a FAQ etc. or another
list please let me know. I have followed your posts for about a week now and
am very impressed with everyone's knowledge.

I am working on a Mac dual G4 in PS6.01 and printing to a Epson  1270. I
have scanned a 5x7 B & W glossy print with no texture on a Microtech
Scanmaster 4. After doing a little retouching and when printing to the
Epson, there is not a  continuous tone using black ink only. Is this normal?
I have been able to get good color prints. I am assuming that not using all
of the ink jets contributes to the problem.

TIA,

John in OKC
