Epson ESC/POS Printer commands

[Dom_Peall]

HELP....

I am trying to get an Epsom POS printer to work.

I have managed the basics, like printing text to it, no problem. i have even managed to get line feed n lines and cut to work.

But, i can not seem to get anything else. i want to print a barcode and also print in red (Colour 2). the manual has examples, but i am not sure how to convert them and send them to the printer.

The barcode code looks like this - 

PRINT #1, CHR$(&H1D);"h";CHR$(80); ← Set height
PRINT #1, CHR$(&H1D);"f";CHR$(0); ← Select font

PRINT #1, CHR$(&H1D);"H";CHR$(2); ← Select print position
PRINT #1, CHR$(&H1D);"k";CHR$(2); ← Print bar code
PRINT #1, "496595707379";CHR$(0);
PRINT #1, CHR$(&HA);

then there is the colour change example - 

PRINT #1, CHR$(&H1D);"(N";CHR$(2);CHR$(0); Color 1 Color 2
PRINT #1, CHR$(48); CHR$(49);← Set character color 1
PRINT #1, "Color 1";
PRINT #1, CHR$(&H1D);"(N";CHR$(2);CHR$(0);
PRINT #1, CHR$(48); CHR$(50);← Set character color 2
PRINT #1, "Color 2";

Programming guide is called "Programming manual APG_1005_receipt.pdf"

Has anyone had any success with this? please share....

Attached code will print, then feed 10 lines, then cut. not tidy, its a work in progress.

Any and all help gratefully received.

Hi Dom_Peall,

There are two potential ways to interact with a printer:

• By using LabVIEW Report Generation Toolkit. There have been successful cases of using this toolkit to interact with POS and dot matrix printers https://forums.ni.com/t5/LabVIEW/Can-t-print-to-Epson-TM-U590-Slip-Printer-from-Report-Generation/td.... For more information please refer to this tutorial on how to use the toolkit http://www.ni.com/tutorial/3201/en/ or have a look at the examples in LabVIEW https://www.ni.com/getting-started/labview-basics/examples. However, due to the number of different printers available on the market, the toolkit's compatibility with each printer cannot be guaranteed.
• By sending commands using NI VISA driver similarly to you what have been doing. By using this approach, you would need to manually write the commands that have to be sent to the printer based on the manufacturer's manual.

Regards,

Vilius
