You must have the manual for the cutter.
Does the manual say that it accepts HPGL?
99.99% of all cutters accepts HPGL
Signlab has a HPGL standard absolute driver.
It is possible your cutter understands multiple languages and just needs to be switched to HPGL on its menu pad.

found this on another site when i googled “dingtech”
“MANY HPGL cutter drivers are inter-changable for MANY brands of cutters. Some Roland drivers run the DingTec flawlessly, as do Graphtec plotter drivers. In SignLab .. the HPGL STANDARD ( Absolute ) driver runs the DingTec flawlessly. Other drivers I have experimented with, work but perhaps have a problem with the STARTING position, or the ENDING routine..some had problems with data accuracy. “
