问题 http://fiddle.jshell.net/bTtKT/show/ If I print the above page in Chrome as A4 Landscape I get two pages as expected given the size of the canvas on the page, if I do the same in Firefox however (with print preview for example), it gives me only one page and therefor cuts the image/canvas in half. If I change the scale in Firefox however I do start to see the whole image (but then it's too small), so the image is there as a whole but Firefox seams to ignore that its bigger then one page for

问题 This is 335th time this question being asked, by I've found no answer. I'm trying to send raw data directly to printer via WinSpool api from ASP.net C# application. My code is just a copy from here. Error goes here if( OpenPrinter( szPrinterName.Normalize(), out hPrinter, IntPtr.Zero ) ) It works fine for local printer but for shared network printer the result of OpenPrinter (result of GetLastError actually) is always 5 - Access Denied . I've tried different values for PRINTER_DEFAULTS with

MS Edge - window.print() is not frame contextual in MS edge

由 风格不统一 提交于 2019-12-21 09:33:41
问题 Microsoft Edge is not handling window.print() consistently when compared with other browsers. In most browsers calling window.print() from within an iframe on a page will only print the contents of that iframe. However in edge it will always print the whole document. Was this intentional? Is there workaround? Example on JSFiddle. iframe.html ... <body> <a href="#" onclick="window.print()">print iframe document</a> </body> ... index.html ... <body> <a href="#" onclick="window.print()">print

Detect if user has printing capabilities?

由 爷，独闯天下 提交于 2019-12-21 09:21:46
问题 A client has asked for a print button be added to their site and would like it to be hidden for users who don't have the capability to print, e.g. most mobile devices. Is there any way through JavaScript to detect if a client has printing capabilities? 回答1: The requirement is flawed since most user agents can "print" and the knowledge of whether or not a UA can print is not the websites busines. Many mobile browsers can print and most web browsers can print even if there is no printer

问题 I am currently using IE9 and media queries and I have no need to have this working from other browsers.

Linux/CUPS printing example/tutorial? [closed]

由 风流意气都作罢 提交于 2019-12-21 08:16:32
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I need to print some vector data (or to be more exact: some dots and polylines) using Linux. When I ask Google for that it shows me many tutorials and documentations - but all for end users, no programming examples. So does anybody know a good programmers HOWTO/tutorial that shows printing under Linux? Thanks!
