[WD 23] Printer port

Hello everyone

I use this code to print text to the POS printer port

// The COM2 port is opened
PortNum = sOpen("COM2", 2000, 2000) // Open COM2
IF PortNum <> 0 THEN
sMessage is string
// Send a message to the output buffer of COM2
sWrite(PortNum, sMessage)
// Wait for the end of the write operation
LOOP
IF sInExitQueue(2) = 0 THEN BREAK
END
Info("End of write operation")
sClose(PortNum)
END

1. How can I get the port name of the printer I choose?
I use the command iInfoPrinter(Printer, iDeviceName) but it always shows me the port of the default printer

2. How can I change the font size of the text that is printed directly on the port?

Thank you

You are writing directly to the COM2 port and in that case the printer may not even be installed in the OS.
If the printer is not installed on the OS I don't think you can find the name.

To change the font size witing directly in the com port you must check the printer manual to find what is the escape sequence for that.

Hello Infos

iInfoPrinter() only shows the default printer

iListPrinter will give all the printer names
sPrinterList is string
sPrinterList = iListPrinter()

I can get a list of printers by name, but I need the port name for the selected printer
