Android barcode printing with Bixolon SPP-R200II -

-

i need print barcode in mobile bluetooth printer brand “bixolon” model “spp-r200ii” android application. using bixolon sdk android work samsung sii not motorola moto g g2. decided not using sdk, instead sending commands printer based on “unified command manual” bixolon. using these lines:

string codigo=”1234567894”; int gs=29; int k=107; int m=5; byte[] codigobytes=codigo.getbytes(); outputstream.write((byte)gs); outputstream.write((byte)k); outputstream.write((byte)m); outputstream.write(codigobytes);

based on manual command should print “itf” barcode not. connection printer stablished; can print text not barcodes command. has had better luck in printing barcodes method , printer? appreciate , comments.

you have missed 1 important part while printing bar codes. should end nul sign. add this:

string nul = new string(new byte [] {0x00}); outputstream.write(nul.getbytes());

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
