  • ot:hacking a printer?

    I've seen many sites where people have hacked keyboards and other peripherals but i cant find one that shows how a printer is hacked! Has anyone come across one or does this site that I'm looking for simply not exist? By hacking I am referring mainly to the control of the ink jet nozzle.

    That would be pretty hard to do. It's controlled by a local cpu in the printer and the code is in rom, probably on the same chip. You could probably do a fair bit of fooling around by writing your own printer driver for it but that would require documentation on the printer that usually isn't available.

      This might not be the exact hacking you're looking for, but it is a neat application of hacking an ink jet to directly print a circuit board layout for etching: (may require registration to view)

        Here's some info about controlling a cartridge directly:

          perhaps i can write my own driver. I should have asked, is there a website that shows which combinations of inputs triggers which nozzles?

            I have a friend that rewrote the programing for a Canon printer and burned the new program on an EPROM chip to do a special printing job.

            Pretty heady stuff for most of us.

              what is the best language to write a driver in? c? can it be done in Java? ...or do i have to go to an even more basic language?

                Elninio,

                It would probably depend on exactly what machine you are on but device drivers are usually written in C with timing critical sections in assembly code. Depending on what you're trying to do to the printer, it might be possible to write a program to handle it that doesn't go to the trouble of being a device driver. Such a strategy usually works for devices that connect to the serial port and just need a program to send the right bits out the port.

                  Mind listing some of the sites that hack keyboards and other peripherals?

                      Here is a DOS TSR program that allows you to connect switches to the parallel or game port and use them to generate keyboard key presses. If used in conjunction with Turbo CNC it could be used with a switch style joystick or directional buttons for jogging or manual milling. It also supports a proportional joystick on the game port.

                        hacking a printer!

                        A little while back, I bought a part from MSC. The salesman said he would send me a photocopy of the page with the specs for the part I ordered. Imagine my surprise when the part came with their entire hard bound 5 1/2 thick MSC catalogue!
                        Later, I went to a Grainger's about a mile away from my job on lunchtime and bought a reamer. Asked for a catalogue. They said they didn't have one.
                        I said that was all right, I had a MSC catalogue. BOOM!--instant Grainger catalogue appears from underneath the counter. Go figure. I guess they just do not want to sell to the little guy.
