Installing DLGraph

    Before installing this software, make sure you meet the program requirements. You must have:

      1. Any IBM compatible PC run version of MSDOS, version 3.3 or higher.
      2. 512 K of conventional memory.
      3. VGA display for viewing PCX image on screen.
      4. Parallel or serial port connection.
      5. Mouse supported but not required.

    DLGraph is really quite simple to install, there’s not even a real setup program. Just:

    That’s it, your done! Now let’s create an image to load on the printer. This part’s kind of tricky, so pay close attention.

Scanning/Preparing an Image

    I recommend using Microsoft Photo Editor to scan your images, I’ve had real reliable success with it. The image can come from anything – a business card, a menu or even a TO-GO bag. I’m going to tell you how we do this in-house, it’s not necessarily the ONLY way to do it, but it works for us.

    First, place the image on the scanner bed

      1. Launch Microsoft Photo Editor.
      2. Select Acquire from the File menu. If you’re asked which TWAIN module to use, select the 32-bit one.
      3. Now perform a preview scan of the whole area so that you can select just the image area you want to scan at high quality.
      4. Once you’ve got your preview, use the selection tool to select the portion of the image you wish to scan at high quality.
      5. Okay, you’re about to scan, but WAIT! Here’s the tricky part: You have to create a file that fits within the parameters Seiko has specified for the printer. Oh…. I see, and what are those huh? Well I’ll run them down for you:

                1. File size – 14k (for Star emulation)
                2. Width – 510 pixels (the size of the paper roll)
                3. Height – 215 pixels (at 69 dpi, the max size of the image is 510×215 because that’s also equal to the 14k file size)
                4. Color Depth – black and white (that’s the same as 2-bit)

          Jeez, that’s kind of technical huh? Don’t worry, it’s easy to do. You’ve got your image selected right?

                1. Set your DPI to 69.
                2. Now you have to play with the value in the Output Scaling field to adjust the height, width and file size values. Keep in mind that you don’t have to max out these values. Also note that if you want the image to be centered on the paper, you will need to make the image 510 pixels wide or leave enough room to play in the file size to create a new file that you paste your scanned image into.

      6. Okay, okay, NOW scan it.

    So you’ve scanned an image, you should be good to go. If your image wasn’t 510 pixels wide and you want to center the image on the paper when it prints you have just a few more steps to do:

    These steps require Paint Shop PRO. The reason is weird – Sometimes you will see garbage on your image in DLGraph that you can not see in ANY graphics program. This shareware program that is the ONLY program I have used to date that doesn’t not create that stuff. (Unless you convert a file format, like from TGA to a PCX. In which case it will make junk too)

      1. Launch Paint Shop PRO
      2. Create a new file with these dimensions:
          Width – 510 pixels
          Height – whatever, as long as the file size remains at 14k or less.
      3. Paste your scanned image in to the newly created file.
      4. Center it and save it.

    Alrighty then! Now you’re ready to load the image on to your printer.

Loading the image

    Before you try to load your neato image, make sure your printer’s DIP switches have been properly configured to remember the image once turned off. For more on this, you should read the document dedicated to the Seiko DPU-3372 thermal printer. (I recommend you only use STAR emulation!) Once you’ve verified your printer’s setup, your ready to begin.

      1. Launch DLGraph by typing DLGraph2 from the directory where you unzipped the DLGraph zip file.
      2. Now choose Printer from the menu bar.
      3. Select Setup from the Printer menu.
      4. Now, choose the printer mode you’re using and the port it’s connected to. Mode A is for EPSON emulation and Mode B is for STAR. If you have a serial connection, do this next:
            1. Select Serial Setup from the Printer menu.
            2. Configure the port.

    Here’s an excerpt from the documentation for DLGRAPH:

    Open PCX image:

      1. Select File from the menu bar, and choose Open from the menu.
      2. From the File List Box, select the PCX file, then select Okay.
      3. PCX image will display on the screen, then press any key to return  to the program.

    Download PCX image into the printer:

      1. After printer had been setup and PCX file had been selected, select Printer from the menu bar.
      2. Choose Load from the menu, then select the printer area for the PCX image and select Okay.

    Printing Download Graphics image:

      1. From the menu bar, select Printer, then choose Print or Print All.
      2. If Print is selected from the menu, then select the area of the printer to be printed.Select printing resolution, then select Okay button.

    To Clear Printer Image Area:

      1. Select Printer from the menu bar, then choose Clear Area.
      2. Select the area to clear, then select Okay button.

    Using Demo Printing:

    Configuring the software using Printer Setup, according to your printer hardware setup.

      1. From the menu bar, select Printer, then choose Demo.Select demo file to be printed from the File List Box, then select Okay button. The sample demo files are for MODE A (Epson TM-T80 emulation setting), except the file named MODE_B.372 which is the sample print out of
          MODE B (STAR emulation setting)

    Additional Printer Control:

    Configuring the software using Printer Setup from the Printer Menu.

      1. From the Menu Bar, select Printer then choose Cut Paper-Full or
          Cut Paper-Partial, or Form Feed Paper (available in mode A setting).

    To Rotate the PCX image:

    Select Image from the Menu Bar.Choose Rotate. The PCX image will rotate 90 degree clockwise.

    Printer Command for Printing Download Graphics:

    Printer set to mode A only:

    In the case where an image occupies more than 1 area, the HOST must define each individual area and output them consecutively to create the “total” image.

    Use the following command to print the stored image:
    Command:  GS + “/” + m + n
    Code:          1DH + 2FH + m + n                    0< m<3: Print mode.
                    29    47    m  n                    0< n : Area Number.

    m = Print ModeVertical dot densityHorizontal direction dot density
    0 Normal        180 DPI x 180 DPI
    1 Double-width  180 DPI x 90 DPI
    2 Double-height 90 DPI x 180 DPI
    3 Quadruple    90 DPI x 90 DPI
