Emulate ZPL printer

Step by step to install on windows (tested in windows-10):

1. Install the ZPL Printer app from the Chrome store
2. Run the app and make sure it's toggled On.
3. Open Printers & scanners or Devices & Printers in Control Panel.
4. Add a printer. (Optional! Only if you select from control panel)
5. Select "The printer I want wasn't listed"
6. Select Add a Local Printer. Then next
7. Create a new port - Standard TCP/IP. Use IP 127.0.0.1
8. Let Windows detect the port and it will eventually return an error.
9. Select Device Type -> Custom.
10. Press settings and make sure you have IP Address 127.0.0.1, Protocol RAW and port 9100.
11. Click OK and Next.
12. Wait for it to fail to detect driver model.
13. Select Generic and Generic/Text Only.
14. Next a few times then Name your printer.

15. Create your test script

    ^XA
    ^FO250,40^A0N,70,70^FDLPN^FS
    ^FO30,120^A0N,50,50
    ^BCN,100,N,N,N
    ^FD1000001^SFddddddd^FS
    ^FO200,300^A0N,50,50
    ^FD1000001^SFddddddd^FS
    ^PQ50
    ^XZ
    

16. Print, select your new named printer and Print.
17. Viola!

So, to emulate ZPL printer on your mac (possibly windows too):

1. Install this chrome app Zpl Printer
2. Go to printer settings, add new one.

Port can vary. Double-check it.

3. Make sure everything turned on.

To test it, try in your terminal:

lp -o "raw" -q1 -d zpl <<< "CT~~CD,~CC^~CT~^XA~TA000~JSN^LT0^MNW^MTT^PON^PMN^LH0,0^JMA^PR6,6~SD15^JUS^LRN^CI0^XZ^XA^MMT^PW508^LL0203^LS0^BY4,3,138^FT48,155^BCN,,Y,N^FD>;12^FS^PQ1,0,1,Y^XZ"

If everything tuned properly, in ZPL printer you will see:

Works on windows as well. Tested it on windows-10.

After installation of Chrome App (link provided by @ZuzEL) and Printer Install, open Notepad and type ZPL code, print it on this newly added printer and "voilá"!

As a @Bill request, I've added some screenshots of my windows printer properties, after install. It's a TCP/IP printer with Generic/Text Only driver, on IP 127.0.0.1 and port 9100, the defaults of chrome app.
