c# - Printing with XPSDocumentWritter on an Epson printer PrintQueue -

-

we have application have print function works on printers except products epson on windows 8. i've manage make minimal sample reproduce problem. call following method, providing full path correct xps file.

private void print(string xpsfilename) {   if (string.isnullorempty(xpsfilename))   {     return;   }    printdialog printdialog = new printdialog();   printdialog.showdialog();   printqueue defaultprintqueue = printdialog.printqueue;    try   {     // seems fail epson printers: no job in spooler, no print ...     printsystemjobinfo xpsprintjob = defaultprintqueue.addjob("print through 'addjob' on printqueue", xpsfilename, false);   }   catch (printjobexception printjobexception)   {     console.writeline("{0} not added print queue.", xpsfilename);     console.writeline(printjobexception.message);   }   catch (exception exception)   {     console.writeline("{0} unknown error:", xpsfilename);     console.writeline(exception.message);   } }

you see if choose epson printer no job appear in spooler whereas work other printer.

does has idea why it's not printing (the job not appears in spool) ? in real application not use xps file rather use paginator, sample purpose it's simpler , fail ...

thanks help.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
