Issue title: slow printing in libreoffice
 Issue body: I don't know if this is the right place for reporting....

I'm using libreoffice, which supposedly uses this project for printing. I'm on xubuntu 20.04.

My hw is quite good, AMD Ryzen 7 with 8GB ram

If I send to the printer a 4-pages A5 document printed as a brochure, printing 1 copy requires some seconds for processing it, printing 100 copies requires at least 5/10 minutes of processing. Pinting 1000 copies requires hours of processing.

My questions are:

- Is it a cups issue or a libreoffice one? who is responsible of such a long processing time: cups or libreoffice?
- I'd think that printing 100 copies should be equivalent to process one copy and send 100 times the same processed work, but it doesn't seem to be such that.
- the processing job uses one core. Is there a way to use more cores?

 Comment 0: @paolobenve What printer are you using? What driver? How is it connected?

"lpstat -v" and a copy of the PPD file from /etc/cups/ppd would be good information to start with.
 Comment 1: @paolobenve 
as general background information regarding "printing copies"
you may have a look at
https://en.opensuse.org/SDB:Printing_Copies

By the way regarding LibreOffice
see a likely old and meanwhile fixed issue in
https://en.opensuse.org/SDB:Landscape_Printing
which I show here mainly as an example that
printing issues can become rather complicated.

 Comment 2: > What printer are you using?  What driver? How is it connected?

Canon imageRunner 1025N, canon driver for this printer, connected ethernet cable

```
$ lpstat -v
device for Canon-iR1020-1024-1025-UFRII-LT: lpd://stampante
```

`stampante` is defined in /etc/hosts

 Comment 3: @paolobenve So the delay in printing is the LPD connection. Try adding "?mode=stream" to the end of the device URI:

```
lpadmin =p Canon-iR1020-1024-1025-UFRII-LT 'lpd://stampante?mode=stream'
```

 Comment 4: is it ok that in the job attributes I'm seeing `ipp:` and `http:` links?

 Comment 5: @paolobenve I meant to add it to the device URI with the lpadmin command (in my previous comment).
 Comment 6: @paolobenve were you able to test the command Mike's provided?

```
$ lpadmin -p Canon-iR1020-1024-1025-UFRII-LT 'lpd://stampante?mode=stream'
```
 Comment 7: @zdohnal I'm not clear what that command is:
- a print command?
- ad admin command?

What should I expect from it?
 Comment 8: I'm sorry I've missed the '-v' parameter - see the updated command from the previous comment.

It is an admin command - your issue should get better once you run the command and then you print something.
 Comment 9: I think we've found the performance issue here as a configuration problem. Closing.
