Hi Tony,
I can see what you mean about the ink. The cartridge was left in the unit and it has ruined the cartridge although that wasn't likely to be of much use I know
I have been able to clean off the residue and it looks like the Flexi might have a fighting chance. It is a HP and not centronics interface on the back.
I'll see if I can attach it if I make progress with the disk drives and hard disk.
