Answer 1

Finally STAR MICRONICS support answer me

the code to print € symbol is

[commands appendBytes:"\x1b\x1d\x74\x04"
               length:sizeof("\x1b\x1d\x74\x04")-1]; //meto Euro

[commands appendBytes:"\xD5"
               length:sizeof("\xD5")-1]; //meto euro

€ in hex byte values:
UTF16: 20AC
UTF8: E2 82 AC

char utf8[]  = "\xE2\x82\xac";
char utf16[] = "\x20\xAC";
NSLog(@"utf8:  %@", [[NSString alloc] initWithBytes:utf8 length:3 encoding:NSUTF8StringEncoding]);
NSLog(@"utf16: %@", [[NSString alloc] initWithBytes:utf16 length:2 encoding:NSUTF16BigEndianStringEncoding]);

NSString *cost = @"156.95 \xE2\x82\xac\r\n"; // dataUsingEncoding:NSUTF8StringEncoding]];
NSLog(@"Cost: %@", cost);

NSMutableData *commands = [NSMutableData new];
[commands appendData:[@"156.95 \xE2\x82\xac\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
NSLog(@"commands: %@", commands);

NSLog output:

utf8:  €  
utf16: €  
cost: 156.95 €   
commands: <3135362e 393520e2 82ac0d0a>
