3.edit file above again, because redhat-config-printer disable again

Why do you want raw printing? How are you trying to print? Why don't
you set the queue to be raw from the redhat-config-printer tool
instead of editing the file?
Need more information..
I think that's because, I saw when using normal queue, in samba
log says that need raw printing, to get windows printing to linux
printer, beside that windows won't print
I will try this, I dunno before
Then add 'cups options = raw' to the smb.conf file. The mime.convs
file should not need editing.
Hm, I have some problems with printing directly from Windows XP to Cups (XP can
print to Cups directly, no need to install/configure/use Samba). Depending on
the printer driver used on Windows XP, the content type of the print job
changes. This worked perfectly for my old (non-PS) Brother printer. However
for my Samsung ML-1740 printer, XP uses application/octet-stream. It seems that
for this, I need to have raw printing enabled in mime.* files. However, I don't
want the queue to be forced to raw (wich I guess setting the raw option on the
queue in system-config-printer would do). I just want support for
Anyhow, after I configure the printer, Cups complains (in log files) that I need
to enable raw printing. If I uncomment the application/octet-stream lines in
mime.* files, and restart cups, Cups does not complain anymore, however nothing
is sent to the printer either!? Cups simply eats the job with no error message.
I even attempted running cups with debug logging, but nothing usable was logged.
For now, as a temporary workaround, I told Windows XP to use Apple LaserWriter
Color 12/600 device drivers (since that printer seems to have similar margins
and printable area to my Samsung printer, which I found out by trial and error).
Those generate postcript (with appropriate content-type). However, I'd really
like to be able to use Samsung driver, since it has controls for features as
per-job toner economy settings (and some other printer features) that I don't
have access to using PS drivers.
