You can't control the laser with Corel, you have to control it with the program that came with it, usually RD works or Lasercut or whatever their names are

Because their programs are just plain hard to work with as you would in Corel, their main function is to act as a print driver, setting speed, power, etc...

Most programs have a plug-in where you design in Corel, then using the plug-in (which is my case ends up as an icon in the upper menu bar) you transfer what's on your Corel screen to the machine's program. Then it goes from there...
