Subject: [PATCH 05/11] Fix margins problem when printing statistics page on
 MacOS     Despite havine a 3.3 mm margin on Windows, Linux and MacOS use a 12
 mm bottom margin for an HP printer     Set margins to 10,10,10,12 unless
 printer reports a larger margin; then use larger margin     Reduce debug
 messages     Fix regression that trimmed last character from user information
 lines     Continue use of Helvetica font for printing Statistics     Adjust
 column sizes for Standard vs Monthly reports
