pdf - Is there a way to get this "send to printer" Java method to work? - 


public static void sendpdftoprinter(string epsilon) {     fileinputstream psstream = null;     try {         psstream = new fileinputstream(epsilon);         } catch (filenotfoundexception ffne) {           ffne.printstacktrace();         }         if (psstream == null) {             return;         }     docflavor psinformat = docflavor.input_stream.autosense;     doc mydoc = new simpledoc(psstream, psinformat, null);       printrequestattributeset aset = new hashprintrequestattributeset();     printservice[] services = printservicelookup.lookupprintservices(psinformat, aset);      // step necessary because have several printers configured     printservice myprinter = null;     (int = 0; < services.length; i++)     {         string svcname = services[i].tostring();                   system.out.println("service found: "+ svcname);          if (svcname.contains("series"))         {             myprinter = services[i];             system.out.println("my printer found: "+svcname);             break;         }     }      if (myprinter != null) {                     docprintjob job = myprinter.createprintjob();         try {         job.print(mydoc, aset);          } catch (exception pe) {pe.printstacktrace();}     } else {         system.out.println("no printer services found");     } }  public static void main(string[] args) throws ioexception {     //@suppresswarnings("unused")     //testing t = new testing();     string dest = ("c:/users/brian/desktop/so046201r-17/testingalpha/6fs-2m.pdf");     sendpdftoprinter(dest); }

i'm writing program that'll write text series of pdf files , send them printer. i've got writing pdf part done, whenever try passing file "sendpdftoprinter" method encounter problems. far i've tested hp deskjet printer , canon inkjet printer no success (former gave "java document error" message , latter wouldn't add file queue). suppose question boils down this:

is problem code or printers i'm using? there workaround?

using mark's edit:

public static void sendpdftoprinter(string epsilon) throws  invalidpasswordexception, ioexception {     fileinputstream psstream = null;     try {         psstream = new fileinputstream(epsilon);         } catch (filenotfoundexception ffne) {           ffne.printstacktrace();         }         if (psstream == null) {             return;         }     docflavor psinformat = docflavor.input_stream.autosense;     pddocument mydoc = pddocument.load(new file(epsilon));       printrequestattributeset aset = new hashprintrequestattributeset();     printservice[] services =      printservicelookup.lookupprintservices(psinformat, aset);      // step necessary because have several printers configured     printservice myprinter = null;     (int = 0; < services.length; i++)     {         string svcname = services[i].tostring();                   system.out.println("service found: "+ svcname);          if (svcname.contains("series"))         {             myprinter = services[i];             system.out.println("my printer found: "+svcname);             break;         }     }      if (myprinter != null) {                     printerjob job = printerjob.getprinterjob();          try {             job.setprintservice(myprinter);             job.setpageable(new pdfpageable(mydoc));             job.print();         } catch (printerexception e) {             // handle exception.         }     } else {         system.out.println("no printer services found");     }  }

this may because printers don't natively support pdfs. managed print pdf code, printed if pdf file opened text file.

one solution use apache's pdf library java: pdfbox. file can loaded so: 

pddocument mydoc = pddocument.load(new file(epsilon));

to print file, use printerjob instead of docprintjob: 

printerjob job = printerjob.getprinterjob();  try {     job.setprintservice(myprinter);     job.setpageable(new pdfpageable(mydoc));     job.print(); } catch (printerexception e) {     // handle exception. }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
