Hi Everyone

I was hoping someone could point me in the right direction

As you are all aware by now I am writing a EPoS application in Gambas (ive started working on the Back office application now) and I need to print some information to a Zebra Label Printer.

Below is the code I use for the Printer (this was crated by a Zebra program so I know it works as it works on my Windows PC)


I need to print this to the LAN printer that is on 192.168.1.100 Port 9100.

so my question is how do I send data to the printer so it can print? (do I have to add a CUPS driver for it?) or can I send the data direct to the IP address / Port?


Any advice help etc is most welcomed as this was a pain to get working when I was in VB.net lol

I have used cups to send printer data in my POS application. I am sure you can go direct to port but you are limiting yourself to particular printers that way. The problem with zebra (having worked with their stuff) is that they do not have any linux support.

The way my system is designed I don't print direct to the printer from my software I send data to a module and that does the work so I can have any shelf edge label printer on my system as long as I can make a module for it.

I try to use the usb or serial version of the zebra printers but when you're working in the middle of the shop requesting labels for a new install you are limited to what the customers have.

And yea I know just what you mean by Zebra not having any Linux support (oddly though the have Android support)

Also how would I print the port? I've never done that with Gambas (I assume I would need to open 192.168.1.100:9100 as output or something like that)

Maybe by using Socket Class of gb.net:
/comp/gb.net/socket - Gambas Documentation

Have a look here https://supportcommuni…/000022631?language=en_US. I use a Zebra printer at work on Linux, but it is connected via USB. It works well for me. I create PDF files in Gambas and send them to the printer.

 Does that mean I can still send the raw data to the printer driver like I can with the windows version?

Or would it be better to talk direct to the printer?

I create a pdf using gb.cairo, then save the image to the /tmp/ folder. I Shell the lp command, see here,  with the file name, see below. Job done.


This produces labels like this: -

Code (gambas)

1. Shell "lp /tmp/my.pdf" Wait

Do you have any examples of how you used the gb.cairo?

Could I use that to print multiple labels across the page?

Here is a simple possible example:

vuott's code is a good start. The code below is designed to create a PDF file with the words 'Hello world!' and saves it to the /tmp/ folder. The label size is 50 x 25mm (2" x 1")

Could I use that to print multiple labels across the page?

Simply loop through as many time as necessary.
