I have a question about thermal printers. Normally if using w/ with an Arduino, you can set a DTR pin, which allows you to bypass the buffer on the printer. https://learn.adafruit.com/mini-thermal-receipt-printer/hacking
I noticed the libraries in current use for particle don’t have a code block for dealing with DTR. Has anyone tried doing the DTR buffer bypass with spark? Any thoughts on approaches to trying it?
