Default printer settings are ignored

阅读更多关于 Default printer settings are ignored

问题 Using Windows Print Spooler API's, we can print out XPS files. The problem is that the print spooler ignores the default printer settings . (We've given up on trying to apply printer settings. Default printer settings will just have to suffice.) For example... the printouts always come out in colour and on one paper per page, regardless of what the settings are set to in the control panel: black & white/colour, duplex/not duplex, multiple pages per sheet/single page per sheet.

ResetDC() does nothing (print spooler API's for Windows)

阅读更多关于 ResetDC() does nothing (print spooler API's for Windows)

问题 I've written wrapper classes for Windows' print spooler APIs, which work... mostly. The only thing that does not work is applying printer settings . First I call DocumentProperties() to successfully acquire and play with printer settings. Then I try to apply those settings using ResetDC() but nothing happens. The function takes a valid handle, and returns the same valid handle, meaning it should have applied the settings. But, nothing seems to have happened: the printouts are unaffected by

Programmatically set printer to bypass the windows spooler

阅读更多关于 Programmatically set printer to bypass the windows spooler

问题 Is there a way to programmatically configure a printer that prints to a file (local file port) to bypass the spooler service and send the data directly to the file ? I have looked @ prnadmin.dll (nothing relevant there) and WMI (nothing relevant). Any ideas ? And no, I don't want to stop the print spooler service in Windows (XP SP3), just make the printer bypass it. 回答1: The PRINTER_INFO_2 structure has a parameter called PRINTER_ATTRIBUTE_DIRECT. You can get the handle to the printer using

阅读更多关于 How to get the original full file path been printed by Spooler API

问题 I want to monitor the system scope's printing jobs through a standalone program using the Windows Spooler API, but only the print job's name can be fetched. How do I get the original file with full path. 回答1: If you are looking for the original document path (e.g. location of Word Document that you just printed), the spooler will not be able to tell you this. The spooler generally receives files through the GDI or XPS paths. The application that does the printing effectively sends the spooler

问题 Background: I'm writing an application in C# using .NET 4.0. It prints a bunch of documents in a certain order. The documents are of all different types and are actually printed using ShellExecute with the "print" verb. To make sure the order doesn't get jumbled, I'd like to examine the print queue for the printer involved. My main loop would look like: Invoke "print" action on the document Wait for document to show up in print queue Repeat until done How Can I Monitor The Print Queue Using
