  • printing graphics screens

    i am new using PB3.5 and maybe this question is so easy to you,
    i made a program where i use VIEW to define an area on the screen,
    this area is used to made a graphic of dispertion using coordinates
    unitedes by a line each pair of coordinates,and i would
    like to know how could i send this information to my printer.
    Maybe something like LPRINT is to PRINT.

    Well, LPRINT is to the printer what PRINT is to the monitor.
    Just make sure you have a printer attached to your LPT port.
    DOS programs can't get to USB port(s) so if you have a USB
    printer, you'll have to look elsewhere (maybe Lance's DOSPRINT).

    In as far as dumping a graphics screen to printer, good luck.
    The only way that I can think to do it would be to read the
    screen pixels, put the data into a string$ (in accordance with
    your printer specifications) then LPRINT the string to your

      To print a graphics screen you would need to load first.
      You can use a DOS shell command, or load it when DOS starts-up.

      You can even call interupt 5 to print. should be in the DOS directory.

          Uh, that's <U>this</U> topic, Davide.

          GRAPHICS.COM is fine but only if your printer supports DOS -- that is, a USB or Windows-only printer will sink you.

          A more flexible way would be to save the screen as a BITMAP file, and then print it from a windows app (or print to *ANY* printer from your DOS app using a product like my DOSPRINT utility. Note: DOSPRINT supports about six different image file formats such as PCX, JPG, etc, so you are not limited to BMP).

          Source code to create a bitmap from a DOS graphics screen can be found at

          You might also find some useful stuff in the DOS GRAPHICS area at

          I hope this helps!

              Well, heres a cool trick that works with some of the HP printers...
              It's useless for on the fly images, but if you can create an image
              in advance and know what printer will be used, you can try this.
              It should work with all printers, but I've had problems with a few.
              First things first, you install a new printer using the driver for your
              target printer, but set the port to "file". Then print your graphic (from paint or wherever)
              using that printer. Choose an appropriate file name. Next, open the file
              in edit, or notepad... or create a program which does the next step for you.
              Finally, remove the LAST chr$(12) (form feed) from the file.

              You now have a driver created image of... your image. Without the form feed,
              it should print where you tell it to, so you can print text before and after it.
              This is great for adding a signature or logo to a form that you will
              print out on a known printer.

                Wanted to add... like I said, it DOES NOT always work, but it usually works,
                especially on older printers that are not Host based. It works on some
                host based printers as well. But be warned, if it does not work, you
                better have the printers power button or cord ready to go
