Plotter file starts with "MK"

Hi all,

I have this plotter file (.plt) that uses non-standard HPGL commands.

I don't know its origin or what program has produced it. It is a job file for a Chinese made vinyl cutter.

I really need to know what these commands are.

So, here is the file. I removed most coordinates to make it shorter. It does not have any line breaks or white space.

Code:

---

MK4,4,0,0;IN;PA;SP1;CB1;PU4,4;PD4,5,4,7;PU120,15;PD122,18,125,12,150,33;PU3142,0;!PG;;

---

I need to know what the following commands mean, including their fields:

Code:

---

MK4,4,0,0;
CB1;
!PG;

---

And what is the significance of the double semicolon at the end?

Thank you.

Found that with Google:

Hope it helps

Yes, this helped, thank you.

So, MK4,4,0,0; specifies CMYK values. I am guessing the fields are in the 0-255 range.

The !PG; command should stand for 'Page', which basically means the end of the job. Although I don't know what the deal is with the exclamation mark.

So now, if only I could figure out what CB1; means.
