printing

问题 How can I print to a variable with Perl? I've been working on a program for a while which logs its iterative progress in a highly verbose fashion... print $loghandle $some_message; However, I'd like to also selectively print some of the messages to a different file. Naturally, I could sprinkle the code with... print $loghandle $some_message print $otherloghandle $some_message Or rewrite the whole business into a function. Blah. What I want to do is do some magic when I open the $loghandle so

问题 I've been trying to find where a user's last used printer is stored so that I can clear this usage data (as a few users have an issue where the remembered printer keeps defaulting to the XPS writer, despite us having KB981681 installed & the printer being available; just not defaulted on certain AX forms). I know this data's somewhere in the Usage Data, which I can browse via AX: Microsoft Dynamics AX > Tools > Development Tools > Application Objects > Usage Data AOT > System Documentation >

问题 I'm porting an C# .NET application to Mono .NET for executing in OSX. Part of the application involves printing an image. Fairly easy in .NET and boils down to primarily e.Graphics.DrawImage(img, new Rectangle(x, y, printSize.Width, printSize.Height)); in the PrintDocument's PrintPage event. Mono does not have a full implementation of System.Drawing.Printing so it seems that the best way to go about doing this is using GtkSharp. I've found some examples online as to how to print text using a

问题 I've got page breaks working for print media with a quick page-break-after: always . I use these to separate multiple reports in a single batched print job. Unfortunately, when the print job is double-sided, the page break can cause the printer to start a report on the back of the previous report. Is there any way to force a page break to an even page? Or, alternatively, to detect which page number a certain element will appear on? 回答1: There's no built-in functionality in CSS for this. An
