Our Mobile models ER-58A and ER-80WF are already approved and listed by Loyverse officially.
If you are looking for cost-effective model that supports driving cash drawer, choose our ER-80IVW WiFi Desktop Printer,it could work perfectly with both Android and iOS Loyverse POS. ER-80IVW is also a perfect Kitchen printer with buzzer and light prompt.
here is the link:
You could also watch the youtube video how it works with iOS Loyverse POS to print receipt , print bill, print kitchen order, open cash drawer, activate the buzzer and light prompt.
Below is a general view of the command for the printer buzzer, if it is supported by the printer:
1B, 42, n, t
1 <= n <= 9, the number of beeps
1 <= t <= 9, the length of the sound (it's not in seconds, it's just the preset value) 1 - short beep, 9 - long beep
You can type it in the initialization command line, and then the printer will beep before printing the receipt
1B, 42, 09, 02
In this example, the printer will quickly beep 9 times
** only for ESC/POS printers. It does not fit for STAR family printers.
Look like that's it)
