[Roger <277404@xxxxxxxxxxxxxxxxxx>]

I've found Ubuntu (via the Launchpad Ubuntu bug), as well as the Windows
HP driver seems to be forcing HP product (M1522NF here) to use PS Level
2, even though PS Level 3 is specified.

In other words, you can explicitly state within the application to print
PS Level 3, but you'll get a rendered PS Level 2 file instead without
you knowing it.  I kind of complained this is "hackish" to the Ubuntu
Launchpad filed bug.  At most, the box should be greyed or unavailable
for these products that do not support PS Level 3.

On Gentoo here, cups printer support is setup to obey the user's
configuration files -- as well as probably most others except Ubuntu.
I've made note of the PS Level 3 printing problems for HP products known
on Gentoo Wiki.

(Also note, irrelevant to this bug, using a the HP M1522NF fax plugged
into a phone outlet using DSL with a DSL filter, the fax modem on this
device seems to misinterpret the DSL signals as a fax signal sometimes,
and you'll hear noise through the HP product speaker.  Hard reset is the
only cure, aside from also unplugging the phone/fax line when you're not
using it.)

Bug description:
  Binary package hint: hplip

  Intrepid Beta (fresh install)
  HPLIP 2.8.7-0ubuntu3

  Symptoms: Printing from a text based application like text editor to
  my HP ColorLaserJet 2605Dn (using the recommended Postscript driver)
  results in certain characters being represented as empty squares. The
  number "8", the "<" and ">",  the "/" character and the eol char seem
  to be most affected.

  Changing the document's font does not correct the problem, but it may
  cause different characters to be substituted with boxes.

  My other printer, which is an HP P1215 inkjet (non-Postscript) works
  normally.

  The Laserjet works fine in Hardy. I tried copying the .ppd from hardy
  over the .ppd installed with Intrepid, but the problem remains. (note:
  subsequent testing indicates this para is incorrect.  I had forgottent
  to restart CUPS. The Hardy .ppd does in fact correct the problem as
  noted below).

  If I set the Laserjet to use the generic Postscript driver I lose some
  control features, but what does print is correct and the problem does
  not manifest.

  To repeat the issue:

  open text editor and enter the string

  ***this is a printer system test
  1234567890abcdefghijklmnopqrstuvwxyz/.,<>?***

  print the document.  The "8" character, the "/" character, the ">"
  character and the eol character will be represented by a hollow
  square. I don't see any equivalent in the Latin character set chart.
