I am using this sample code,

/* Example of using GS DLL as a ps2pdf converter. */

#ifdef _Windows
/* Compile with:
* cl -D_Windows -Isrc -Febin\ps2pdf.exe ps2pdf.c bin\gsdll32.lib
*/
#include <windows.h>
#define GSDLLEXPORT __declspec(dllimport)
#endif

#include "errors.h"
#include "iapi.h"

gs_main_instance *minst;

int main(int argc, char *argv[])
{
int code;
int exit_code;
const char * gsargv[10];
int gsargc;
gsargv[0] = "ps2pdf"; /* actual value doesn't matter */
gsargv[1] = "-dNOPAUSE";
gsargv[2] = "-dBATCH";
gsargv[3] = "-dSAFER";
file://gsargv[4] = "-sDEVICE=pdfwrite";
gsargv[4] = "-sDEVICE=Xerox Phaser 8200DX";
gsargv[5] = "-sOutputFile=out.pdf";
gsargv[6] = "-c";
gsargv[7] = ".setpdfwrite";
gsargv[8] = "-f";
gsargv[9] = "input.ps";//this is the default testing PS file
gsargc=10;

code = gsapi_new_instance(&minst, NULL);
if (code < 0)
return 1;
code = gsapi_init_with_args(minst, gsargc, gsargv);
gsapi_exit(minst);

gsapi_delete_instance(minst);

// if ((code == 0) || (code == e_Quit))
// return 0;
return 1;
}

with "-sDEVICE=pdfwrite setting, it can convert ps to pdf,

I want to send that ps file to my printer, don't how to set all the argv,
my printer is Xerox Phaser 8200DX on a LAN,

when I run the code, it says "unknown device Xerox Phaser 8200DX", don't
know what name should be set here, and all the argv settings.

That is a PostScript printer. Why would you want to use GhostScript?

I think you have the role of GhostScript confused, to be honest. It is
not a print spooler.

if not use GS, are there other ways to send postscript command to a PS
printer in C ?

richard yu

there is another way to send PS to printer, didn't try it yet.

Well, that would depend on how the printer is connected to the host
running the C program. If the connection is serial (e.g., RS-232),
you can pretty much write characters to it more or less as if it
were stdout, although the details will be platform-specific. If it's
a network connection, things could be considerably more complicated
and quite certainly platform-specific.

If your platform happens to be unix, it would probably be best to take
advantage of the lp subsystem. Again, your C program won't have to do
too much more than write characters as if it were writing them to stdout.
W. Richard Stevens' "Advanced Programming in the UNIX Environment"
[ISBN 0-201-56317-7] has a chapter devoted to "Communicating with a
PostScript Printer" that you might find helpful.

As Aandi suggested, ghostscript is not a print spooler, and serves little
or no purpose when the printer has a PostScript interpreter.

But lp *is* a print spooler, and one that's quite capable of working with
PostScript printers. --
