I haven’t been able to print barcodes on the 5890 model thermal receipt printer, and it looks like other developers can’t either.
The same printer is sold under a few names. As far as I can tell (mainly from bug reports to escpos-php), these are all the same printer, and could have this issue:
- AGPtEK SC35-5890F
- EC Line 5890
- Gainscha GP-5890
- HSPOS HS-589C
- WinBond 5890
- Zjiang ZJ-5890 or POS-5890
In my case, I have a Zjiang POS-5890C, which list the barcode command GS k in its documentation, but does not actually respond to the command.
Separately, a developer has contacted their vendor and confirmed that this is an error in the documentation.
A few bookmarks for reference:
How to test for barcode support in USB printers
Get yourself a Linux computer or VM, set up the printer with usblp, and run this command:
echo -e '\x1d\x6b\x04000\x00' > /dev/usb/lp0
This command prints a CODE39 barcode containing ‘000’ on printers which support barcodes, and prints garbage on printers which do not.
