由 吃可爱长大的小学妹 提交于 2020-01-03 11:47:10
问题 What is a scalable algorithm to print an N-binary-digit integer manually whose value does not fit in long long . I know printf and friends, along with <iostream> (which most likely piggy-backs on <cstdio> have this builtin for standard types, but I'd like to do it for an integer composed of N bytes. I have thought about this and googled a bit, but it always comes down to using a pre-existing bigint libirary like GMP (a codebase I am not at all familiar with) or "use printf" or the most

Printed output not displayed when using joblib in jupyter notebook

由 落花浮王杯 提交于 2020-01-03 10:56:26
问题 So I am using joblib to parallelize some code and I noticed that I couldn't print things when using it inside a jupyter notebook. I tried using doing the same example in ipython and it worked perfectly. Here is a minimal (not) working example to write in a jupyter notebook cell from joblib import Parallel, delayed Parallel(n_jobs=8)(delayed(print)(i) for i in range(10)) So I am getting the output as [None, None, None, None, None, None, None, None, None, None] but nothing is printed. Actually,

Capture print dialog's cancel in silverlight printing

由 爷，独闯天下 提交于 2020-01-03 10:44:54
问题 Does anyone know if you can find out if the print dialog's cancel was clicked? I've seen post and doc that say "EndPrint – Event fired when the printing is either completed or canceled. " But I don't think that is the print dialog's canceled... I think the is if the print job is canceled. thanks 回答1: Based on the documentation, I don't believe there's an easy way: http://msdn.microsoft.com/en-us/library/system.windows.printing.printdocument.endprint(v=VS.95).aspx In particular: The EndPrint

Firefox prints extra blank page

由 一笑奈何 提交于 2020-01-03 08:53:18
问题 I have a web page that prints correctly on Chrome, Safari and IE, but has the followign problem on Firefox: It prints just the header on the first page. The rest of it is blank. The actual content is shown only on page 2. Googling a bit about it i found that the "float: left" style is causing it. If i remove the "float: left" it prints ok, but it does not look as it is supposed to as it needs to display 2 columns beside each other in print as well as on screen. Is there a solution to this

How to create a pre-scaled font for a CPCL printer

由 一个人想着一个人 提交于 2020-01-03 05:07:14
问题 I've got a .NET Compact Framework application that uses a Zebra QL220+ printer. I drive the printer via CPCL printer language, and I now need to print some output that cannot be achieved with just the resident fonts. I'd like to create some pre-scaled fonts (which are then downloaded as .cpf files to the printer) but for the life of me I cannot find how to do this. I have the Label Vista tool from Zebra, and despite the fact that the Help file states this can be done, my "Fonts" menu is

由 谁说胖子不能爱 提交于 2020-01-03 04:02:44
问题 I have (in Python 3): print('event {} happened on these dates: {}'.format(event_name, date_list)) My date_list is a list of datetime.date objects. I would like to change the format from: event A happened on [datetime.date(2011, 5, 31), datetime.date(2011, 6, 15)] to event A happened on [2011-05-31, 2011-06-15] What's the best way to achieve that? I was hoping I could keep using the format() function, but I don't see how. 回答1: Printing a list gives the repr of the items inside the list. To get

How do I print a pdf from within an iframe?

由 心已入冬 提交于 2020-01-03 02:47:08
问题 At cbjsonline.com, I'm trying to have a pdf in an iframe print automatically with javascript. Currently, my code is - (connected to the onclick of the link that opens the iframe) - document.getElementById('fancy_frame').onload = setTimeout('window.print()',2500); Any suggestions? This method only works in safari. 回答1: Try passing a function pointer to setTimeout, instead of an expression that gets eval'd. document.getElementById('fancy_frame').onload = setTimeout( printWindow, 2500 ); //

How do I send a PDF in a MemoryStream to the printer in .Net?

由 不打扰是莪最后的温柔 提交于 2020-01-03 02:27:46
问题 I have a PDF created in memory using iTextSharp and contained in a MemoryStream. I now need to translate that MemoryStream PDF into something the printer understands. I've used Report Server in the past to render the pages to the printer format but I cant use it for this project. Is there a native .Net way of doing this? For example, GhostScript would be OK if it was a .Net assembly but I don't want to bundle any non .Net stuff along with my installer. The PrintDocument class in .Net is great
