printing - Setting up USB-serial Receipt Printer (epson tm-t88ii/iii compatible) on Debian Wheezy -

-

i'm trying receipt printer working on debian wheezy.

on being plugged computer, usb-serial receipt printer (epson tm-t88ii/ii compatible) tics question marks every few seconds, , not respond commands.

the output printer is:

˥ ?????????????????£???≡█

attempting print echo fails error:

/dev/ttyusb0: permission denied

even root.

attempting open cash drawer fails error:

/dev/ttyusb0: no such device

how stop tic , print?

here's how got working:

after sending:

# echo "test" > /dev/ttyusb0

returns permission denied,

# dmesg | tail

returns:

[92780.658576] ftdi_sio 2-3:1.0: ftdi usb serial device converter detected [92780.658624] usb 2-3: detected ft232bm [92780.658626] usb 2-3: number of endpoints 2 [92780.658628] usb 2-3: endpoint 1 maxpacketsize 64 [92780.658630] usb 2-3: endpoint 2 maxpacketsize 64 [92780.658632] usb 2-3: setting maxpacketsize 64 [92780.664556] usb 2-3: ftdi usb serial device converter attached ttyusb0 [92782.102904] usb 2-3: usbfs: interface 0 claimed ftdi_sio while 'brltty' sets config #1 [92782.104874] ftdi_sio ttyusb0: ftdi usb serial device converter disconnected ttyusb0 [92782.104891] ftdi_sio 2-3:1.0: device disconnected

this indicates there conflict package 'brltty', (braille device), installed default.

# apt-get remove brltty

stops tic

set baud with

# stty -f /dev/ttyusb0 9600

try echo

$ echo "test" > /dev/ttyusb0

it prints!

what cash drawer?

$ echo -e "\033\0160\0\031\372" >> /dev/ttyusb0

it opens!

problem solved. unless need braille display well.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
