Well, I usually write to the Z-buffer at twice the resolution that
I want to see on the display. For example, here is your modified
code. It looks OK on my display, but perhaps I'm not that picky
for display purposes. Now, hardcopy, that's something else. :-)

PRO TEST
thisDevice = !D.Name
set_plot, 'Z' ; open gif
!p.font = 1 ; set font
Device, Set_Font='Times', /TT_Font, Set_Resolution=[800, 800]
plot, indgen(5), title = 'Main Plot Title', $
xtitle = 'X-Axis Title', ytitle = 'Y-Axis Title', $
color = 0, background = 255, charsize=2.0 ; Twice normal size characters
xyouts, 0.5, 3, 'Annotation', color=0, size=4

image = tvrd() ; capture plot from Z-buffer
set_plot, thisDevice
window, 0, xsize=400, ysize=400
tv, Rebin(image, 400, 400) ; display image
END
