I also added a, although i don't know what that does that EndPagePrinter, EndDocPrinter and CloserPrinter don't do. i don't have device units, logical units, world coordinates, margins, padding, text size, points, pixels, etc - which i believe GDI likes to use.Ĭhanging the KB article code to use "TEXT" as opposed to "RAW" does solve the problem - the " Save As" dialog appears properly. The same code is also used to print to a dot-matrix receipt printer, which needs to print using it's own printer fonts, and i also need to be able to send a FormFeed code. My question would be: how do i send raw text (and some control codes) to a printer using GDi? i don't want it to render in Times New Roman, Ariel, Helv, Courier New or anything true type. Plaintext for you by rendering the job via GDI to the driver.ītw, you should also call AbortPrinter in case of any exception, so that the The print processor attached to the driver will then "convert" the You mightīe able to send plain text to the driver if you specify "TEXT" as theĭatatype. Click on Printer and follow the onscreen instruction. Click on view all, this will list all of the in built troubleshooter. If you want to render text on the XPS driver, you should use GDI. Type troubleshooting in the search box and then press enter. XPS driver will probably, if any, only accept XPS data when you write XPS, and it will probably just ignore your "unknown: adfasfasdf" PDL. But the XPS driver will probably only understands Well this probably is because you send "RAW" data directly to the printer,Īnd RAW can be any PDL. Length(TextToPrint), dwBytesWritten) then If not WritePrinter(hPrinter, PChar(TextToPrint), Inform the spooler the document is beginningĭwJobID := StartDocPrinter(hPrinter, 1, dwJobID = 0 then As you step through the wizard, youll come to the Install the printer. Fill in the structure with info about this SizeOf(DocInfo)) Go to Control Panel > Hardware and Sound > Add a printer. Next, choose 'Add a printer', and select the following options: 'Add a local printer'. Raise Exception.Create(' Cannot find the printer "'+PrinterName+'".') To reinstall the Microsoft XPS Document Writer on Windows 7, first delete the 'XPS Document Writer' icon from the 'Printers and Faxes' section of the 'Devices and Printers' folder if it exists. If not WinSpool.OpenPrinter(PChar(PrinterName), hPrinter, nil) then Raise Exception.Create(' To text specified') HOWTO: Send Raw Data to a Printer by Using the Win32 API The filters in the rendering module of an XPSDrv printer driver must also support the Print Ticket technology to correctly process the print job for the printer.įor more information about installing XPSDrv drivers, see XPSDrv Installation.Procedure PrintStrToPrinter(const TextToPrint: string const PrinterName: Instead, the render module of an XPSDrv printer driver consists of zero or more filters and a configuration file that describes the actions of each filter. The render module of an XPSDrv printer driver does not, necessarily, use the GDI-based rendering functions of a GDI-based printer driver. The v4 print driver model continues to support many familiar technologies like XPSDrv, GPD, PPD, Autoconfiguration, and Bidi. The configuration module of an XPSDrv printer driver provides the same functions as the configuration module of the Printer Interface DLL of a GDI-based driver, but the XPSDrv configuration module also supports the Print Ticket and Print Capabilities technologies. The v4 printer driver model is a refinement of the existing v3 printer driver model, and it was designed to improve driver development, reduce IT management costs, and support new scenarios. These are the three main components of XPSDrv printer drivers: XPSDrv printer drivers (like the GDI-based ones) consist of three main components. The XPS printer driver (XPSDrv) is an enhanced, GDI-based Version 3 printer driver that was used prior to Windows Vista.
