Možda će nekima izgledati malo ne interesantno, ali svejedno meni se čini da bi moglo većini uštedjeti vremena kada su POS printeri u pitanju…
Primjer u Javi.. radi na svim Epson Esc kompatibilnim printerma novije generacije, kao i bloutooth printerima..

Moj prijedlog je da podijelimo iskustva koji POS printeri po modelima (godina proizvodnje) mogu a koji ne mogu generirati QR kodove iz QR Byte pripremljenih podataka..
