HP UDP 6.4.1 - MathType 6.9 objects in Word

[slantin_cegepbc]

Since we have updated the driver 6.0 to 6.4.1, a user noticed that the MathType Objects in Words, the printing output isn't the same on the screen.

In the equation | x | ,   the symbol " | " is larger than usual.

If we switch back to UDP PCL6 6.0, it  prints fine.

Even the version 6.3.0 have the same problem printing output.

The solution we found is to disable the printing optimization, but I would like to know if there's a known issue or official solution from HP ?

I don't know the answer, just a bit of background:

What this almost certainly does is to render the whole page as (a series of) raster images on the workstation, whereas using print optimisation, the data is probably rendered on the printer by usikhng characters within a font.

Depending on which font is being used, this could be a printer-resident font, or a soft font which is dynamically generated (from a donor TrueType/OpenType font on the workstation) and downloaded to the printer within the print job  stream.

Why there should be differences between versions of the UPD, I don't know (perhaps different fonts assumed, or different library routines to generate those soft fonts, etc.?).

'Capture' (i.e. 'print to file') of sample print jobs, then analysis of those jobs, may (but, of course, may not!) yield some clues as to the differences.
