If you spray any liquid on fresh printing, I think it would run.
The only thing I know of is Bubble Jet Set.
Wash sizing out of your fabric first, then spray on Jet Set. Allow to dry then iron flat. Cut to A4 size.
You will need to attach to sticky A4 paper to take through the printer. You can buy them, or spray a little adhesive on the paper, mainly the edge that goes into the printer first.
After printing you wait 24hrs I think and set with a hot iron.
Try googling Bubble Jet Set and you should find out more and where to buy.
Hope I have helped
