> So I'm trying to get as low level as I can with my Dymo label printer, and this method described the PDF http://sites.dymo.com/Documents/LW450_Series_Technical_Reference.pdf seems to be it.

Perhaps if you were feeling generous and wanted to write a bit of sample code, sending the "Get Printer Status" command and receiving the response (page 17 of the PDF) would be perfect to get me on my way.

1) what OS?
2) does the printer appear as a serial port by the OS? Or as a
printer device?
If it appears as a serial port, you may want to obtain the pyserial
(or whatever the name is this year) package. For USB, you may need one
of the variant USB packages (pywinusb, pyusb, etc.) With luck you won't
need to use admin privileges to access the port as a raw device vs
having to go through an OS driver...
