[GNC] How to adjust Column Widths in Reports? Also is Print Preview Supported?

[Adrien Monteleone]

Your best bet for editing reports beyond the Options or whatever the 
Stylesheets function can adjust is to export or select-all/copy/paste 
into a spreadsheet app and manipulate from there.

Otherwise, you could also export and script the editing of the resulting 
HTML table. (You could maybe create a new CSS-based stylesheet within 
GnuCash for just the Transaction Report where you could probably target 
certain columns, but that depends on them having a hook to target. 
Adding such hooks would require a truly customized report which requires 
editing the Scheme code.)

I rarely send to paper, but I do seem to recall some platforms 
(particular Flatpak) having some issue with physical printing, (due to 
the sandbox) though not sure if that is resolved. (I think there was 
always a workaround for that though)

You may want to try first 'printing' to PDF, which would at least give 
you the desired preview, then print from whatever app you used to view 
the PDF.

Adrien
