having the same issue, it takes around 5 seconds for the print request to complete, probably if it were paired, could work better

same issue, have you solve it?

codeRuth commented 4 years ago

same issue, have you solve it?

ended up using another library, this library works with the paired devices, rather than connecting it every single time as a new device.

but am still using this library for Network mode
