[comp.sys.mac.system] Weird graphics on Print Directory printouts

omalley@mace.cc.purdue.edu (John O'Malley) (04/18/91)

A colleague on campus called with a strange problem.  When she does a
Print Directory in Finder of a locked floppy disk, the printout has weird
miscellaneous graphics bits on the page, which is otherwise the directory
printout one expects to see.

These are clearly not toner smudges.  The graphics have jaggies ...  like
bitmap lines often do.  It's as if someone was in MacPaint with a 2 or 4
point paintbrush, moving the mouse around randomly, occasionally clicking
to draw.  The random graphics are different on every printout.

But this only happens when printing a directory of a locked floppy.
Unlocked floppies and hard disk directories print fine.  And no other
printing problems from applications.

She uses a Mac SE/30, System 6.0.5, 1 meg RAM, no unusual CDEVs/INITs
(except maybe Gatekeeper, which I don't use but have the impression
that it's relatively stable).  LaserWriter IINT.  Most of her work is
in Microsoft Word.

Any ideas?

We've had similar problems.  The "weird graphics" are the padlock, out
of position and ridiculously enlarged and distorted.  We noticed the
problem on a machine running Multidisk (partitions hard disk and
controls access to the partitions), and we thought the problem was
some incompatibility with that program.  It appeared only when using
Print Directory from the Finder for a locked disk, so we decided not
to worry about it.
