I did the 8000+ photo cookies for Showtime using my Canon IP4000 printer, and I kept wondering all the way through the job whether or not the Canon would survive. It wasn't new when I started the job, and I printed at least 1000 icing sheets. It did survive the job and a little beyond, but then the heads became clogged, and I wasn't able to clean it out using the normal clean function, and at the last minute I had abandon it in favor of a new printer.
I purchased the Epson Workforce 30 printer in February 2009, and I immediately contacted Kopykake and got the cartridges for it (note: I had already confirmed by their website that they supported the Workforce 30). Well... things have gone downhill with the printer since then.
1. It didn't want to pull the "ink" through the printheads - so it wasted almost the full five cartridges (at $90!!) before it finally printed! So after that I got about 3 or 4 icing sheets printed and then it was out! And I had to spend another $90! I changed them out today and then it didn't want to recognize them because they weren't Epson cartridges (it took a while to get over this issue).
2. It makes a terrible racket just feeding through each sheet of paper or icing. I'm glad I didn't have to listen to that when doing the Showtime job.
So... now I am taking my two Canon IP400 printers to be repaired - which probably just entails a profession deep cleaning of the print heads.
Canons are work horses and last longer, are quieter, and they are not ink hogs. The Epson is a terrible ink hog.
Just my 2 cents worth.
