[Epsonepl-users] Re: RAW printing to EPL-5900L?

[O. G. <OG...@we...>]

Samba is compiled against CUPS (ldd smbd shows it depends on libcups).
Anyway, it is just an ordinary install of Mandrake 9. I installed the
printer using Mandrake's printerdrake using the ppd files created by
your driver. Below I post you the important lines of my smb.conf:
[global]
printing = cups
printcap name = lpstat
*snip*

[printers]
   comment = All Printers
   path = /var/spool/samba
   browseable = no
# to allow user 'guest account' to print.
   guest ok = yes
   writable = no
   printable = yes
   create mode = 0700
# =====================================
# print command: see above for details.
# =====================================
   print command = lpr-cups -P %p -o raw %s -r   # using client side
printer drivers.


I think the most important entry is the "print command" direction which
tells Samba to first spool the input to a temporary file and then
execute the command given. This way, there is actually no need for the
right drivers as the raw data, spooled by windows, is sent "as-is" to
the printer, isn't it?

To conclude, printing works using the ominous -o raw command. I'm really 
confused about this one since mime.convs tells me to enable 
"application/octet-stream ..." to "allow printing of arbitrary files 
*without* the -o raw option". This, however, does not seem to work as 
you can see at the failure trying to print using IPP.

A smbclient -L ... actually gives me exactly one printer - the one I
configured. But nothing like "CUPS [translated]".
Unfortunately, I cannot give you any more input as I myself can't figure
out how this thing exactly works (especially concerning CUPS).
