Antoine,

Thank you for the report. Unfortunately, this behavior is the expected 
one on the HP OfficeJet Pro 9022.

I went to HP's site and pulled the specifications on that particular model.

The only printer language supported in that model is that which they 
term 'HP PCL3 GUI'. It neither supports HP PCL 5/PCL 6, nor PostScript.

PCL3 GUI is common in many of the inkjet printer models these days, and 
relies on the host computer to do all the graphics and text image 
processing before sending all the data as an image to the printer. 
Generally, a PCL3 GUI printer contains no built-in fonts nor high-level 
text or graphics routines.

Since I've been asked off-list about the various printer languages in 
today's printers, here is a small chart:

1. HP PCL3 GUI   - graphics only from host printer driver; contains no
                     built-in fonts nor high-level text or graphics
                     routines / common in modern ink-jet printers
                  - these type printers will NOT support 8-bit text
                     output from programs such as AppleWorks or BASIC
                  - these do NOT understand PostScript

2. HP PCL 5 / HP PCL 6  - intelligent languages with built-in fonts and
                            that support numerous high-level text and
                            graphics commands
                         - these WILL support 8-bit text output from
                            programs such as AppleWorks and BASIC,
                            and also from GS/OS desktop programs that
                            use the Harmonie or Independence printer
                            drivers
                          - these do NOT understand PostScript

3. PostScript emulation - intelligent language that supports output from
                            a PostScript Printer driver
                         - these support GS/OS Desktop output from the
                            Direct Connect PostScript Printer Driver and
                            also from 8-bit programs such as PublishIt! 4

Many of the printers that support #2 will also support #3 and will be 
able to auto-switch between the two. Virtually all modern printers that 
support #3 will also contain #2.

The surprising thing (to me) is that since HP owns the rights to PCL 5 / 
PCL 6, it would cost them nothing to include it with any of their 
printers OTHER than the additional memory and processing power required, 
which wouldn't amount to much. Strangely, HP never asked for my opinion. ;-)
