Anyone familiar with Java and processing here I could use a hand. Citizen GSX 140 Printer hack..

[Chri O.]

Long story short after pulling out of the closet my over 30 years old Citizen GSX 140 printer after bit of cleaning to my surprise it's alive. 😁

EDIT : GSX 140 🙂

Well next thing you know I built a device to spy on printer port and hook up to modern computer.

This turned out to be fun project 😷

I've been learning Processing and Java for like a week only but here is the outcome.

And here is my problem I need to somehow figure out printer settings in processing using Java.

For now I can only show you this I need to make better example.

// By default, Processing loops through draw() continuously, executing the code within it.
// However, the draw() loop may be stopped by calling noLoop().
// In that case, the draw() loop can be resumed with loop().
void draw()
{
  // To do: I need to prepare example...
  
}

// function is called once every time a key is pressed.
void keyPressed()
{
  if (key=='p' || key=='P') myPrinter.StartPrinting();
  println("Press key p or P to print new img.");
}

Sadly I have no experience with Java or Processing, but I'd like to post this message just to say that the project looks very cool!

Thanks everyone.

Well the good news is I think I did figure out the Printer page image resizing issue. 😃

Any one up for testing the Printing application on other computer.😃

You are more than welcome please let me know....

 

Here are my executable application files for ~ Raspberry Pi 32 64 Bit ~ Linux ~ MS Windows.

Only tested on MS Windows 10 so far, Mac OS app will come later.

 

Print Job Example, Key 'P' or Mouse click to open the print window.

Just a quick update..

I made this Epson ESC/P Parser APP (Work-in-Progress) with Atari ST ASCII to Unicode lookup table.

You can choose system installed fonts or fonts from app sketchPath("Fonts") folder.

😃

I partially implemented Canon Bubble Jet Printer BJ10s emulation  😷 360 by 360 dots per inch (dpi) for high resolution graphics.

int W = 2880+20;  //  20 for extra p. margin
int H = 3600+40; 

 

Now I need 8K monitor 😁

I just figured out PDF Export....😷 thanks to Processing PDF library.

The PDF library makes it possible to write PDF files directly from Processing. These vector graphics files can be scaled to any size and output at very high resolutions. 

 

Smaller files but very high resolutions.
