Hi
Does anybody know which driver and fonts comes preinstalled on the Serial Inkjet Printer Driver Board? I need to reinstall the factory driver + fonts. Parallax support could not answer me, so I hope someone here has any experience with installing drivers on this board!

    I have used the Serial Inkjet board, but I didn't supplant any of the firmware in the board, I simply fed it serial data from the stamp:

    Injet Demo

    How exactly did you manage to remove the default font?

    This can be referenced in the "Inkjet Applications" text.· Page 180 of the text will give you information regarding the programming of the drivers.

    Hi
    I don't have the book right here, but I guess you refer to reinstalling the HP5160x.SXB driver. I have tried two different drivers: the original driver and the updated driver which deals with a problem which arises when cycling power on/off - causing all the diagnostics leds on the board to light up and fry the printer cartridge.

    Both drivers produce the same result - the board prints out nothing, and whenever I push the Boe Boards reset button some of the diagnostics led light up again and stays lit depending on which character I try to print out.

    I really have no idea how or if I have managed to remove the fonts though. I have never used the SX chip before and I'm not an expert when it comes to programming or electronics. What I thought would happen when updating the driver was that only the driver would be updated and the fonts in the EEPROMs would be intact. But since nothing works now, I would like to get the exact fonts + drivers that were preinstalled. Perhaps I have managed to fry my printer board? Installing the original setup would help me find this out...

    OK, so if I have understood everything correct; the Inkjet Driver Board is preprogrammed with the HP5160x.sxb driver from the book, or HP5160x2.sxb from the Parallax website. On page 180 of Matts book on Inkjet Applications it says that the 24LC64 EEPROM contains two separate fonts, the utility and enhanced font on page 214.

    The HP_Load_Font program sends the font in maps like this to the Basic Stamp:

    C47···········DATA··· Word %000000000000
    ··············· DATA··· Word %000000000100
    ··············· DATA··· Word %000000001000
    ··············· DATA··· Word %000000010000
    ··············· DATA··· Word %000000100000
    ··············· DATA··· Word %000001000000
    ··············· DATA··· Word %000010000000
    ··············· DATA··· Word %000100000000
    ··············· DATA··· Word %001000000000
    ··············· DATA··· Word %010000000000
    ··············· DATA··· Word %000000000000
    ··············· DATA··· Word %000000000000


    _A············ DATA··· Word %000000000000
    ··············· DATA··· Word %000001000000
    ··············· DATA··· Word %000100010000
    ··············· DATA··· Word %010000000100
    ··············· DATA··· Word %010000000100
    ··············· DATA··· Word %010101010100
    ··············· DATA··· Word %010000000100
    ··············· DATA··· Word %010000000100
    ··············· DATA··· Word %010000000100
    ··············· DATA··· Word %010000000100
    ··············· DATA··· Word %000000000000
    ··············· DATA··· Word %000000000000

    "C47" refers to the ASCII code of the "/" charachter. "_A" refers to "A". So far so good.·Now here is my question: The character maps of the utility/enhanced fonts looks like this:


    ;N=0047 002FH
    x=12 Y=12
    01·········· ............
    02·········· .........0..
    03·········· ........0...
    04·········· .......0....
    05·········· ......0.....
    06·········· .....0......
    07·········· ....0.......
    08·········· ...0........
    09·········· ..0.........
    10·········· .0..........
    11·········· 0...........
    12·········· ............

    Should I change the:

    ;N=0047 002FH
    x=12 Y=12

    to C47, like in the basic stamp program?

    And another thing that puzzles me: After Installing the HP5160x.sxb driver the dieagnistics LEDs on the Printer Driver board lights up whenever I try the example programs, Simple_Print.bs2 or Printer_Bot.bs2. Can this be caused by missing fonts in the EEPROM?
