Digital BW, The Print

To all that offered help and to MIS thanks.  My problem was resolved
and I am printing using the MIS ink set.  MIS sent a replacement
cartridge and that resolved my problem.  There were propably other
solutions but wanted to try my new setup before investing more.  MIS
was very rsponsive to my problem.
