Send data to printer

shercua

I'm trying to send data to the printer using API gdi32.dll. For example I want to send H1B + H40 (hexadecimal values of ESC @). What specific API (gdi32) command should I use? I've been using gdi32.dll API Reference to control my printer, so it's better if I use API gdi32 too. I know how to send data using WritePrinter winspool.drv, but I can't interface that command to the gdi32 API. Thanks for any help I can get

Also, is anyone here familiar with the gdi32 call to "escape" (api-printing). What if I want to send data (eg. ESC @, or hexadecimal values like 1B, 40) to the printer, can I use extEscape functions? What is the format and please let me know how to use the extEscape function. I don't understand the PASSTHROUGH, cbInput, lpszInData parameters. Can you send me a sample code? I really appreciate it if you can. Thanks.
