CellQuest data in Photoshop?

We resurrected our Mac running CellQuest 3.3 and want to print data we 
are acquiring  in color.  Unfortunately, the printer that came with our 
Vantage at that time (1998, I believe) was not a  color printer.  I 
found a way to make pictures of the color data appearing on the monitor 
(apple key, shift, 4) but can't remember how we transfered these 
'pictures' to a PC to print in Photoshop which I believe we used to do 
(and we've been told we can do).

Can anyone help us with this?  We don't have Photoshop, Canvas, 
Powerpoint, Word, etc. on the Mac,

Thanks.
