High resolution frames from an animation

Hi.
This is my first attempt at Processing, sorry for the silly questions.
I need to save frames at 300 dpi minimum for professional printing.

I tried to use a frame 4 times the size of my monitor, but I really need to see what's happening when I record so it does not work for me.

Instead I tried to use the PDF library but I only save 'blank' frame, I don't understand why.

Is there a better way of saving at high resolution, if not, can you tell me what's wrong with my code?

Thank you for your help!

import processing.pdf.*;

boolean record;

int num = 60;

int colorL=255,k = 0,j=100,i=200;

float x,y,z;

float r,th=0,step=.1,epi=200;

float m = 1,n1=-1,n2=0,n3=0;

float b=1,a=1;

int counter1=0, counter2=0;

void setup()

{

size(1800,1100);

background(0);

frameRate(50);

smooth();

}

void draw() {

if (record) {

// #### will be replaced with the frame number.

beginRecord(PDF, "frame-####.pdf");

}

{

fill(0,5);

rect(-5, -5, 1805, 1105);

counter1++;

if (counter1 == 75) {

m=int(random(3,60));

n1=random(2);

n2=random(2);

n3=random(.1);

epi=random(50,200);

step=random(.01,10);

counter1 = 0;

}

translate(mouseX, mouseY-100);

stroke(colorL,35);

noFill();

beginShape();

for(int i=1; i < num; i++) {

r = epi*pow(((pow(abs(cos(m*th/5)/a),n2))+(pow(abs(sin(m*th/5)/b),n3))),(-1/n1)) * random(10000)/random(1000);

th = th + step;

x = r*cos(th);

y = r*sin(th);

curveVertex(x,y);

}

endShape();

if (record) {

endRecord();

record = false;

}

}

}

// Use a keypress so thousands of files aren't created

void mousePressed() {

record = true;

}
