B4J Question How to send printing to Custom K3N?

[amorosik]

I need to create a procedure for sending receipts to a Custom K3N printer
Have you ever created a procedure in B4J to activate communication between a PC and a fiscal printer?

How are you connecting to it?
If it is visible in the PC's printer list, you should be able to choose it to print to with B4j Print Library.

Via ethernet
No, actually is not visible on printer list

So it seems that there are two possibilities.

1) You need to install a proprietary driver to print to it, which seems unlikely looking at the advertising or
2) You need to install it on your PC as a network printer. If I remember correctly you can get the printer installation routine to search for network printers.

The printer you mentioned is a fiscal printer; commands must be sent via TCP-IP socket using its specific protocol.

Send me email, i'll send you protocol manual.

If handles ESC/POS then there is a library dedicated to that, but it might need updating to handle the wired internet connection.

Actually, there seem to be several, but this one rings a bell the loudest:

SD EscPos Printer (Lan,USB, Bluetooth SPP, BLE)

This library allows you to print with thermal printers compatible with the ESC POS language in 4 different communication channels (USB, Bluetooth SPP, BLE, LAN) you can download the ble3 library from here The DEMO version prints one minute every 2. The full version of the library will be issued...

It is a donation-ware library, but from what I've seen, @Star-Dust provides brilliant support, and if his library helps eke the best out of your apparently top-of-the-line printer, then I'm sure it'd be a worthwhile investment.

Yes in B4J

For network printer, I use Socket class to connect to the printer and use AsyncStreams to print.
