Re: Incompatibility with UNIX printing system style - interface file

Hi,

Thank you for your replies.

Still, I can't figure out how to do what I want. The main reason I post the
message was that I want the entire job (even if more files are specified
from the lp command) to be transferred to the printer within a single
connection to the printer.
I have my own backend that is called from the interface script, but since
the interface script called for each file specified in the lp command,
transfer to the printer within a single connection is impossible (my
backend is opening a connection to the printer each time it is executed).
So I tried to use the lpd backend by using "-v lpd://myprinter/PASS" in the
lpadmin command when creating the queue. But still, for each file sent, a
connection is opened (probably the lpd backend is called for each file
specified).

So, is there a way, in the CUPS printing system, to have a single printer
connection opened for a lp command (even if more files are specified) ?

Thank you again.

Regards,
Cosmin Bonea

It is not impossible, but it requires a lot more logic/code in the
interface script - that's what we did back in the ESP Print days on
IRIX, Solaris, and HP-UX, and it was very difficult to manage...
