PrintSpoolerAPI işlevini kullanın SetForm() C#

Question

Özel bir belge yazdırmak istediğim Windows Forms Uygulaması üzerinde çalışıyorum. Bu özel belge özel boyuttadır ve C# kodu kullanarak varsayılan sayfa boyutunu ayarlamanız gerekir.

Bazı Google aramaları yaptım ve PrintSpoolerAPI ile karşılaştım. Bulduğum kod, yazdırma için kullanılabilir sayfalar listesine AddForm() yöntemini kullanarak özel bir form/sayfa ekleyecektir. Ayrıca yeni eklenen sayfayı varsayılan yazdırma sayfası olarak ayarlamak istiyorum.

kod

bool x = SetForm(hPrinter, paperName, 1, ref formInfo); 

Bir true değer döndürür ama onun varsayılan baskı sayfasını ayarlama değil bu çizgiyi yazma çalıştı.

dmPaperSize bu konuda herhangi bir rol oynar mı?

Answer 1

Kodunuz neredeyse kusursuzdur (ihtiyaçlar 64 bit modda çalışabilir) ve bunu yapmak niyetinde yapar: iyi haber bittiği yerde ancak var

. Doğrudan yazıcı sürücüsüne görüştüğünüz API ve DEVMODE değişikliklerinin etkili olmasını sağlamak sizin sorumluluğunuzdadır. Bu XPS yazıcı sürücüsü için iyi çalışıyor, diğer birçok sürücü için iyi değil. Ben de Hewlett Packard sürücüsü gibi denedim.

Yaptığınız her şey kayıt defterinde hemen görünür bir yan etkiye sahip. Regedit.exe ile görebilirsiniz. Kodunuzu iki kez kontrol etmenin iyi bir yolu. Ve bunu görmeyi denemek için yazıcı sürücüsü işbirliği yapmayacak çünkü denemelisiniz. Control \ Print \ Forms \

• HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet: tuşları bakmak istiyorum. Bu anahtar, eklediğiniz formu listeler. Bununla ilgili bir sorunun olmamalı.

• HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Print \ Formlar \ MJM 80mm * Makbuz Uzunluğu, "FormKeyword" değeri. Bunu yazınız, formunuzun yazıcı tarafından seçildiği "anahtar kelime" dır.

• HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Print \ Printers \ printername, "Varsayılan DevMode" değeri. Bu SetPrinter() çağırdığınızda yazılır. Değerin hex dökümünde bakabilirsiniz. Önceki adımda yazılı FormKeyword ofset 0x348

• HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet Control \ Print \ Yazıcılar \ \ yazıcı \ DsDriver, printMediaSupported değer görünür olur. Bu konuda tam olarak emin değilsiniz, ancak kağıt boyutlarının bir listesini göstermeli ve özel formunuz orada görünür olmalıdır.

Kötü haberler için üzgünüm, yazıcılar emicidir.

Answer 3

Teşekkür kullanmak için, benim gereksinimi C# program tarafından belirli bir yazıcı için varsayılan pagesize kuruyor, sonra da açık web tarayıcısı belirli bir web sayfasını yazdırmak için.

Artık özel sayfa formumu eklemeye ve dmFormName değerini varsayılan olarak ayarlamaya çalıştım. Sonra yeniden almak DEVMODE yapı, dmFormName ben değiştirildi budur, ancak not defteri veya diğer uygulamayı açın ve bir şeyler yazdırmaya çalıştığınızda, varsayılan Pagesize belirlediğim ne değildir görüyoruz.

Ayrıca, kullanılmayan tüm sayfaları, varsayılan olarak yalnızca bir tane olacak şekilde silmeye çalıştım, ancak yalnızca kendim eklediğim bir tane silinebilir.

Sadece BİZİM özel pencereler yazıcı sürücüsü için özel bir kağıt boyutu eklemek için benzer bir kod kullanılır. Görünüşe göre bazen işe yaramaz ama sebebi yazıcının sürücü GPD dosyası. Bu dosyada, ÖZELLEŞTİRMEDEN özel bölüm yoksa, yazıcının HERHANGİ ÖZEL kağıt boyutunu asla kabul etmeyecektir. Herhangi bir yazıcıya özel kağıt eklemek için standart pencere prosedürünü kullanarak kolayca kontrol edebilirsiniz.
