Which printer model are you using?
I guess this was not a problem for you in older versions? Which was the version it last worked in?

Buovjaga, were you able to reproduce this.

I just reproduced it with 6.1.6.3, and choosing *printing to file*, so it’s independent of the printer driver.

I didn't try. I don't know, if printing to file is applicable in this case. What is the expected result with files?

Create a Writer document, click on print, choose *printing to file*, and increase the number of copies to, for example, 3. Then click on the button *Print*, and choose the location for the file. Open the PDF file, and notice that instead of three pages it consists of one page.

Hmm, yes, Microsoft Print to PDF does do it like that. However, the issue with printing to file is different from your original issue. I confirm the issue with printing to file, but not with printing to an actual printer. My printer is Canon LBP7018C. Please tell, which model you are using.

What does Microsoft have to do with this?

I am not sure about that. But anyway, will you create a separate issue for that, so it does not get lost?

It is an Epson WorkForce printer.

Microsoft has to do with this as a reference point on how printing to file works on other systems besides Linux or LibreOffice. A user might as well expect it to print multiple files with some incrementing ID suffix.

Maybe.

Let's focus on the issue with the actual printer here.

@Paul: Does it still happen with a current daily build of master? If so, can you please attach your printer's PPD file, which should be located at /etc/cups/ppd/<PRINTERNAME>.ppd?

Michael, does it work for you?

(In reply to Paul Menzel from comment #9)
> Michael, does it work for you?

Yes, works fine here for me on Debian testing with a Canon MX395 printer. I just printed two copies of a one-sided Writer doc without any problems.

Are you printing from Writer as well?

At a quick glance, printing multiple copies is handled by the CUPS printing system (on Linux), so it might be helpful if you can attach the CUPS log as well (/var/spool/cups/error_log), i.e.

* set 'LogLevel debug' in /etc/cups/cupsd.conf
* restart cups: 'sudo systemctl restart cups.service'
* print from LO
* attach /var/log/cups/error_log (or the relevant part for the print job)

In my case, e.g. the params passed to CUPS are shown as follows in the log (but more may be useful):

> D [21/Apr/2020:15:55:26 +0200] [Job 1462] argv[0]="Canon_MX390_series"

where 'argv[4]' is the copy count (which is 2, as it should).

And I'm using current master, should that play a role:

Yes, I do. To not waste paper, I print blank pages.

It is the same here.

```
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[0]="EPSON_WF_2660_Series"
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[1]="370"
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[2]="paul"
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[3]="Unbenannt 1"
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[4]="2"
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[5]="collate PageSize=Letter job-uuid=urn:uuid:b10e8928-dfa5-3ce4-614e-eca53c47bd2a cups-browsed job-originating-host-name=localhost date-time-at-creation= date-time-at-processing= time-at-creation=1587925432 time-at-processing=1587925432 document-name-supplied=VjPFgt"
D [26/Apr/2020:20:23:52 +0200] [Job 370] argv[6]="/var/spool/cups/d00370-001"
```

So, the copy count is passed correctly to CUPS, pointing to a CUPS error.

PPD for Epson WorkForce 2660

This actually looks like it might be a problem outside LibreOffice.

I see nothing obvious in the PPD file.
Some more questions:

1) Does printing multiple copies work from other applications?

2) What happens if you try to print 2 copies of a one-sided PDF file from command line like this (having a PDF file "test.pdf" in the current directory)?

  lp -d EPSON_WF_2660_Series -n 2 test.pdf

3) What happens if you try the same as in 2) with the PDF file generated by LibreOffice for printing? That one should be in /var/spool/cups/d<JOB_ID>-001 ? (In case you have set PostScript to be used as print format in LibreOffice, this will be a PostScript file.)

Apparently not. It does not work in Evince either.

That also prints just one copy.

Same thing. The PDF in the spool directory with only one page, and printing that with the command above also just prints one file.

I am using Debian Sid/unstable with *cups* 2.3.1-12, and *printer-driver-escpr* 1.7.7-1.

I am going to close it for now, but GTK+/CUPS issues also concern LibreOffice.

PS: The reason, I reported this to LibreOffice was, that at work, as far as I remember, LibreOffice with our Canon printer also displayed this error.

Thanks for the update.
