Tim,

I ran a couple of tests with different windows drivers and with and
without cups options = raw.  First a disclaimer, the printer I used for
the test is not directly connected to my linux box.  It is a remote lpd
server, sending the print jobs via jetdirect to an HP Laserjet 8150.  I
do not have any locally connected printers.  If you think it will make a
difference, I can rerun the tests at home.

In all tests printing = cups was specified in smb.conf.

Test 1
Windows:  	HP8100 PS Driver
Cups:  		mime.* commented out
Samba:  	no cups options
Result:  	raw PS printed (i.e. PS commands)

Test 2
Windows:  	HP8100 PCL Driver
Cups:  		mime.* commented out
Samba:  	no cups options
Result:  	Windows test page printed correctly

Test 3
Windows:  	HP8100 PS Driver
Cups:  		mime.* commented out
Samba:  	cups options = raw
Result:  	Windows test page printed correctly

Test 4
Windows:  	HP8100 PCL Driver
Cups:  		mime.* commented out
Samba:  	cups options = raw
Result:  	Windows test page printed correctly

Testing with the uncommented mime.* octet-stream options seems
unnecessary at this point.  The "cups options = raw" samba options seems
to take care of.  From the docs I read earlier this morning, I would
have expected that to be the default when specifying "printing = cups".

>From my perspective:  Using "cups options = raw" seems to abate
modifying the mime.* files, and is a better solution since I don't
believe the smb.conf file gets overwritten each time samba is updated.

BTW:  The above testing on RH9 produces no output for test 1 and works
correctly for test 2.  The "cups options" parm is not available in RH9's
samba.  I must uncomment the mime.* octet-stream lines for RH9 to print
PS from windows, but not PCL.  I would have expected the opposite.

Bob...
