You have the Pyramid pulse printer - not the POG printer.
I'm hoping you have 4 dip switches on the side of the printer.
If so, dip#4 should be "down" to be in the "On" position to act as a POG printer.
Normally Dips#2 & Dip#4 are "ON"
Here's a link to the manual for the PHX printers...>>>

Do you have the pinout diagram for your CM version?
Below is a photo of the printer label with the dip options.
