Slice and dice,
Ihad the thing working yesterday, printed out lettering in vinyl master, it is connected by a usb port, and I will try other numbers to call them. I only use this during the summer when I am doing gym floor logos. I have used other devices in the com port 3 that the plotter is using and it recognizes the other components, so yes I have test other things in the com prot that I have tried with the plotter. I have uninstalled driver for vinyl master and plotter and reinstalled, it does have a rs-282c port, a 9pin cable port, besides the parrellal port cable. that it wil the nest tthing to try.
never heard of sign blazer, just using software that came with plotter.
