Hello
I usually use the [NetworkPrinter] class.
I've been able to use this without any problems.
However, I also want to use it with USB, so I'm also using [SerialPrinter] and creating a Printer interface as follows:
Printer printer = new SerialPrinter(p_connect, 9600);
I can print, but white lines appear.
At first I thought it was a printer problem, so I connected to LAN or WiFi, and when I used NetworkPrinter, the printout was clear.
When printing, if it's a network connection, the printer prints immediately.
If it's [SerialPrinter], the printer is a little slow, and it seems to print one line at a time.
