You can find the edible ink online, I brought in a litre of each colour a few years back for my mother (Will try to find the name of company). Then just bought generic empty cartridges and fill them up. You can use almost any printer I think, provided it doesnt bend the page when feeding and hasnt been used with normal ink before.
Yeah was thinking of maybe going that route. Where did you order the ink from (if you could remember)?
If I can find a place that sells the ink in bottles, will be more than happy to but a new printer and just fill the cartridges myself - will also work out cheaper in the long run as we are paying nearly R200 per cartridge when we need to buy new ones.
