I would like to change the POS commands in the app to open the cash drawer. The command for my MUNBYN bluetooth printer is 27,112,0,50,250 , but LOYVERSE app will not allow the entry of more than 2 digits before a comma, 3 digits can not be entered before a comma. Any assistance is greatly appreciated.
I am currently using Zjiang ZJ-8250 (http://www.zjiang.com/en/init.php/product/index?id=36) with Loyverse in bluetooth mode.
The printer generally works fine, but it prints out gibberish every other receipt. Here is the sequence of the problems.
1. First receipt, the printer prints out and do the auto cut just fine.
2. Second receipt, the printer prints out until the last line of the receipt, but does not feed the receipt out and do the auto cut. (I have to manually pull and tear the receipt.)
3. Third receipt, the printer prints gibberish and do not cut.
The problem seems to be similar to this post:
(Similar in both problem and the printer itself.)
However, I cannot set it to print in text mode as the thread suggested, because I need to print Thai characters. So, I am stuck with image mode.
I have tried with a few esc/pos commands, like resetting the printer, line feed and such with no success.
I tried to find a way to change the printer code page to Thai so that I can try with text mode, but no luck. (Zjiang contact does not response, either.)
Any suggestion would be greatly appreciated.
Need help about printing for my next on a smartphone to terminal printer Bluetooth
I have connected my printer to my android via Bluetooth in Loyverse settings and done a test print and it works fine! When I go to sales top right I normally am able to open cash drawer but option isn't there just synchronise, also in receipts where you can print a older receipt it just shows email receipt. It has been working fine but I deleted printer and tried to link it with another printer which had the same result and now when I try and reinstate the 1st printer I've had problems!
