Sample XLS (with hidden shape)
This is the same as bug 108691, but for XLS files.
In the attached spreadsheet a rectangle covers most of the numbers, but is set to invisible, so it's not shown. It's not shown in Print Preview and when exported to PDF, either. So far so good.
However, it is shown in Print dialog's preview, and also appears during printing, which is bad.
Observed using LO 6.2 master build (e055b4a0fc23e1d0ad5d498f9195790dd41f6b3e) & 3.3.0 / Windows 7.

Reference XLS (visible shape, not printed)

Reference XLS (visible shape, printed)
In Excel hidden drawing object is not printed (at least not shown in the preview), but there's no mention of that in the specification.
The relevant properties for binary formats can be found in MS-ODRAW, under 188.8.131.52 Group Shape Boolean Properties (fUsefHidden, fUsefPrint, fHidden, fPrint).
However, fUsefPrint/fPrint appears to be unused, see the reference spreadsheets. In a hex viewer, look for BF 03 (0x03BF), and the following 4 bytes, which is the Group Shape Boolean Properties structure.
In the sample with the hidden shape this is: BF 03 02 00 02 00
In both reference samples this is: BF 03 00 00 02 00
The aingle difference is the fUsefHidden boolean value on the 2nd bit.
Perhaps there's a similar structure that stores the to-be-printed property as for XLSX files (see bug 108691 comment 4).
Aron Budea committed a patch related to this issue.
It has been pushed to "master":
tdf#108691, tdf#119639 Don't print hidden objects in XLS(X)
It will be available in 6.2.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More

Affected users are encouraged to test the fix and report feedback.
The case in the description should now be fixed, for a related issue I've opened bug 119765.
