Dot Matrix BOLD Printing in Java -


i have written program send raw (text only) data printer dot matrix printer have print provided texts instead of interpreting input image(which makes huge time finish). dot matrix printer installed generic text printer in control panel.

printer - wep 800 dx http://www.wepindia.com/support/support.aspx?itemcode=mfd-0380

printservice service = //my dot matrix print service string input = "esc e bold esc f printing\n"; inputstream stream = new bytearrayinputstream((input.getbytes(charset.defaultcharset())); doc doc = new simpledoc(stream, docflavor.input_stream.autosense, null); docprintjob job = service.createprintjob(); try {     job.print(doc, null); } catch (printexception e) {     e.printstacktrace(); }  // codes // esc e - turn bold printing on // esc f - turn bold printing off

i list of codes from

http://www.lprng.com/distrib/resources/ppd/epson.htm

http://webpages.charter.net/dperr/links/esc_p83.htm

the reason why codes epson because somewhere read these implemented of other manufacturers , cant seem find printer manual printer in manufacturer's website.

but when run program, command codes esc e , esc f printed in paper instead of interpreting command codes.

maybe i'm sending command codes in wrong format. appreciated.

update - got working, @user2357112

char[] bold    = {0x001b, 0x0045};    // esc, e char[] unbold  = {0x001b, 0x0046};    // esc, f string input = new string(bold) + " bold " + new string(unbold) + " printing\n";

output - bold printing

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
