Welcome to HP printers.

As you know, HP generally provides two drives for their larger printers - the 
PS and the PCL.  There are significant differences between the two drivers.  
The PS driver came directly from adobe while HP wrote the PCL driver.  The 
PCL driver was designed to work with drafting programs (AutoCAD) while the PS 
driver is better with drawing programs (Photoshop, illustrator, etc). The PS 
driver will generally give better colors than the PCL driver. You will find 
that the 8500 series drivers have terrible greens (to much blue).  Go into 
the CD that contains the drivers and you will find a file that contains 
tweaked Pantone colors for the PCL.  You can use these to get better color 
output, but the colors will go weird if you send the file to someone else.  
The best thing to do for colors is to create your own color profile (use and 
X-rite colorphotometer) or have a firm like "the digital dog" (at 
www.digitaldog.net) create one for you (cost of 100.00). (they sent you a 
file, you print it out and send them the print out, and they send you an ICC 
profile for your printer).

The PCL driver does not automatically turn on all of the print menu/printer 
options. You must turn them on in the printer preferences screen on the 
computer as well as turn them on in the printer menu itself!  This includes 
which trays (both input and output)  that are active. This probably why the 
11x17 works with the PS driver but not the PCL driver. You will also find 
that several of the options on the print menu screen only work with the PCL 
driver.   

With large plot files, the PCL driver can be incredibly slow.  A plot file 
that takes 5 minutes with the PS driver can take 40 minutes with the PCL 
driver.  However, the PS driver can occasionally plot phantom lines on the 
plots.  This never happens with the PCL driver

You can have both drivers set up on your machine.  Keep the same printer 
node, but slightly change the printer name.  I use simple names such as 
8550PS and 8550PCL.  this allows you to quickly switch from one to the other. 
 Also, unless you are in a large corporate setting, do not use the HP Jet 
Administration software - go to the newer HP printer wizard.  The printer 
wizard is much more stable, but it does not allow you to actively ping the 
printers to see if they are on the network.

There are other differences between the drivers, but you will eventually find 
them out.
