A comprehensive list of printers know to be usable for direct inkjet resist printing is right here:
http://techref.massmind.org/techref/pcb/etch/directinkjetresist.htm under the heading "Printer Modifications". I'll even copy the text in to this post to make Don happy:
Barry Cooper^ reports^ that Epson R2400 (replaced by the R2880) can print on flat stock so no modification of the printer is required. It uses ultra chrome k3 ink which resists etchant if fully cured. Barry says:
"I am currently using 1/16" [PCB stock]. I made a carrier from a for sale sign and a sheet of the colored plastic card that is kept right next to the for sale signs at home depot. The 2 together add up to 1/16 inch. They are plastic and are therefor durable and can be taped to, and the tape removed without damage. I printed on to paper first, then taped the 2 plastic cards together with the paper print on top. Then I cut out the card to the dimensions of the paper and cut the board hole out. Then I pulled of the paper print and taped all 8 edges together, then a piece of paper to the bottom of the card. I am able to drop the board into the hole and it indexes perfectly every time. I use a small piece of tape to hold the top and bottom edge of the board, The carrier fits through the printer with room to spare. My guess is I could go another 1/32 thicker.
Last night I printed in black at only 25% density. Dried the board at 275 degrees for 10 mins then re printed at the same density. Flipped the board and did the same for the other side then oven dried the complete board for 30 mins at 275, It is necessary to let the board cool before re printing as at 275 the ink is like a soft plastic. I then etched with acid and had a fantastic result.
Bazza says "Epson R2400 takes a board up to a4 size straight into it. Print in black and white at 50% Then oven dry at 275 for 10 mins. then re print at 50% and re oven dry, perfect results with zero mods required."
CD/DVD printing trays. (make small PCB's with NO modification!) Artisan 50, Stylus RX580, RX595, RX680, R260, R280, R285, R290, R380 don't really need to be modified, just cut out the CD/DVD spindel in the tray so the PCB can lie flat. This allows PCB's up to about 3x5".
For larger PCB's or other printers, modification allows full sized PCB's to be fed as flat stock:
