Description Ulf Zibis 2014-01-08 14:20:37 UTC
There is some confusion, what LibO should do when "1 3" is typed for the pages to print. For comparison, the behaviour of MS Word 2000:
"1-3" prints pages 1, 2, 3
"1;3" prints pages 1, 3
"1,3" prints pages 1, 3
"1 3" prints nothing
"1-2 3" prints pages 1, 2, 3

1.) I think, LibO should interpret the syntax "compatible" to MS Word.

2.) So "1 3" would be reasonable to interpret as "1,3"; otherwise in extreme cases, plenty of unwanted pages are printed.

3.) If LibO doesn't want to accept the "1 3" syntax, it should throw an error message instead wasting potentially huge amount of paper or doing nonsense as described in bug 44424.

4.) Some applications also deal with "item1 item2" as list of distinct multiple items, e.g. multiple email addresses in To field of email clients. So this seems common expected behaviour.

5.) Like in MS Word 2000, there should be a little hint in the print dialogue about correct/accepted syntax, e.g.:
"Single pages should be separated by Komma Semicola or Blank and ranges by hyphen, e.g: 1,3 5-12"

Hi, the number of printed pages is shown at the bottom of the preview on the left and if you want to have a hint about the syntax, please activate the extended tips in Tools > Options > LibreOffice > General, that will give you all the indication of the separators to use. Currently the 1 3 syntax is considered the same as 1-3 syntax. Closing as not a bug, all the information is present in the dialog - Sophie
Comment 2 Ulf Zibis 2014-01-08 23:45:19 UTC
Hi Sophie,
according 5.) I agree with you - thanks for your hint - but not according 1.) - 4.)

Imagine, someone types "1,3 5,6". From the number of printed pages "1/5" it is not clear, if pages 1,3,4,5,6 or 1,2,3,5,6 are printed.
From 4.) I would expect that 1,3,5,6 are printed.
BTW: In MS Word 2000:
     "1,3 5,6" prints pages 1, 6
     "1-2 4"   prints pages 1, 2, 3, 4
     "1 2 4"   prints nothing
     This is inconsistent either ;-)

The extended tips do not define ' ' and ',' as valid syntax, so IMHO LibO should throw an error message or mention the treatment of those separators in the extended tips.

I still think, ' ' should better treated as ';' instead '-', because of 4.). Only '-' or '..' is unambiguously to interpret as syntax for a range of pages.
Comment 3 Ulf Zibis 2014-01-09 01:19:59 UTC
All commentators of bug 44424 referred to "1,3" syntax, but according the extended tips, "1;3" is the correct syntax, so I feel this as another argument for clarification.
Comment 4 Joel Madero 2014-11-06 03:16:35 UTC
Moving back to UNCONFIRMED as there is no confirmation on the bug. If a 2nd QA member also agrees with Sophie we'll close this and not move it forward but let's wait to see what a second person says. Thanks
Comment 5 A (Andy) 2014-11-06 13:54:41 UTC
@Sophie: 
Could you please help me, how this extended tips function helps here?  To display an extended tip you need to press Shift + F1 and then you need to point to a button or command.  But nothing happens in the Print dialogue (clicking on "Pages" or the input field next to it), so that it does for me currently not help.  If you get there an extended tip, could you please inform whether you had done something different, that I can test it once more if this works also on my LO 4.3.3.2, Win 8.1.  Thank you very much in advance. 

I would propose to add this syntax information to the help page, because currently you can find there no information about this.  For me the help page would be the first place to look for more information, because I suppose most users do not know this extended tips function and would not look for it in the TOOLS menu.

Due to the situation explained above, I unfortunately can currently not fully assess the problem itself.  But nevertheless I think the extended tips is not enough.

Furthermore, the help page needs to be corrected.  The English online LO help page says "Press Shift+F1 or choose Help - What's This? and point to any control element in the Print dialog to see an extended help text."  If you have opened the Print dialogue box then you cannot open the help page at the same time.
In addition, the German translation of the "Tips and Extended Tips" does not say that the extended tips can be shown with Shift + F1.
Comment 6 sophie 2014-11-06 14:12:17 UTC
Hi Andy, I've an extended tooltip if I put the cursor in the field in front of Page. Do you have the help installed on your computer? I just checked and I agree that the help page could be more descriptive about the accepted syntax. Sophie

Comment 10 Dieter Praas 2018-01-06 15:58:09 UTC
Still reproducible in LO 5.4

Actual behavior
1,3 only page 1 is printed
1;3 page 1 and 3 are printed (as expected)
1-3 page 1,2 and three are printed (as expected)
1 3 preview in the printing dialog shows three pages but only page 1 is printed

Expected behaviour
1,3 page 1 and 3 are printed or an error message pops up
1 3 syntax is not clear => an error message pops up

1,3 page 1 and 3 are printed (as expected)
1;3 page 1 and 3 are printed (as expected)
1-3 page 1,2 and 3 are printed (as expected)
1 3 page 1,2 and 3 are printed

=> WORKSFORME

Ulf, if you don't agree, üplease feel free to reopen the bug with a short reasoning.

Case 2 and 3 are OK for me.
Case 1 and 4 are not descripted in the tooltip help.
Case 1 is intuitive, so not a big problem.
Case 4 is not intuitive as with space I would expect that only pages 1 and 3 were printed.

Tooltips are "Extended tips" and it should come from Offline help. 
But:
- help doesn't explain that: https://help.libreoffice.org/6.2/en-US/text/shared/optionen/01010600.html?
- they don't work per Bug 120538.

If I understand this bug well, all works except it's not documented. 
If so, I'll convert to Documentation. 
Current help from 6.2 is https://help.libreoffice.org/6.2/en-US/text/shared/01/01130000.html
But it doesn't explain syntax. 
In "Printing text documents:" there should be a subtitle '"Pages to print"  syntax'.

As for "1 3" I personally agree it could be "1,3" but someone will expect "1-3". I guess no solution for all here. Anyway, let's start with documenting. 

Note: to complicate somewhat, new dialog in 6.3+ doesn't open correct Help: I'll report.
