Hello.
I have to update a printer driver (backend) on Mac OS X 10.11 (should be
compatible down to Mac OS X 10.8) which uploads pdf printing files to our
server where these files will get processed further.
Everything works fine but when I enable cover page I get a server error.
I tried to debug my backend and from the cups error_log I see hat cgbannertopdf
filter is called but I don’t understand how the data of the cover sheet arrive
in my backend.
Basically my backend:
int main(int argc, const char *argv[], char **envp)
{
…
if (argc == 6) {
print_fd = 0;
copies = 1;
} else {
if ((print_fd = open(argv[6], O_RDONLY)) < 0) {
printf("ERROR: Unable to open print file");
return (CUPS_BACKEND_FAILED);
}
copies = atoi(argv[4]);
}
NSString *tmpFilename = [NSString
stringWithFormat:@"/private/var/spool/cups/tmp/ECPF%s.pdf", argv[1]];
int fd = -1;
fd = open([tmpFilename UTF8String], O_WRONLY | O_CREAT);
fchmod(fd, 0777);
while ((bytes = read(fileno(stdin), buf, 256)) > 0) {
if (write(fd, buf, bytes) != bytes) {
close(fd);
}
}
There is data coming from stdin but there is always only the job data in the
tmpFilename not the cover page.
Is there something wrong withy my ppd?
Where do I look for the cover page data?
Thank you very much,
regards,
Robert
