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 application/octet-stream. 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.
