PCL XL error
So here's the issue;
I'm trying to network this printer to the computers in our computer lab. The drivers both PCL5 and PCL6 have been tried and tested STILL I get this error. What I want are the god dang drivers for a Hewlett Packard Laserjet 4050N for windows 7. I don't want your universal driver packages since these don't seem to work. Also the links on this thread don't work.

Based on your comment that you get the same error message on all drivers including PCL5 and PS, I would guess that the printer driver you think is getting used isn't actually what is being used to send output to this printer.
Which printer drivers do you have installed on your system?
Which printer driver is configured as the default for Windows?
(more in a bit... -- please let me know what you have so far)

In Windows7, in the "Control Panel" -> "Hardware and Sound" -> "Devices and Printers" right click on the PCL5 or postscript printer for your 4050, choose "Printer Properties" from the context menu.
On the printer properties dialog, there will be a "Print Test Page" button. Click that and let me know if it works for you to print to your 4050.
If you get the same error message for "Print Test Page", then we'll need to dig deeper. On the same "Printer Properties" dialog box, there is the "Advanced" tab where you should be able to change the driver associated with the device.
If you are not able to resolve the PCL-XL error page with these steps, please let me know.

I had the same problem on a HP LaserJet 4050.
I changed the settings on the I/O menu to the following
Parallel Speed = High
Parallel High Speed = Yes
Parallel Adv Function = On
Serial Pacing = Xon/Xoff
Serial Robust Xon=ON
The Serial Pacing was set to DTR/DSR - and right after I chaned that my printer began working with the HP UPD v5.5 PCL6.
Before changing that setting I needed to use PCL5.
I am hoping others can validate this - as I just stumbled upon it.

PCL XL Error pages gets printed if one or the other file of the driver is corrupted.
The solution to this problem is to upgrade/replace the existing driver which is in use and install a Universal Print Driver for Windows PCL6 (UPD PCL6) or a Universal Print Driver for Windows PostScript (UPD PS).
Please find the link to download the drivers mentioned above.
For UPD PCL6 :
For UPD PS :
The above two drivers should resolve your issue.
I work for HP in Printer Department.
Please send Kudos if you are satisfied with this suggestion.

You may get the PCL XL error utill you autoconfigure the printer. I have networked laserjet 4050's with UPD 32&64bit PCL6 5.8.0 drivers and after installing the printer the test page gave me the error. Because by default under the Device Settings Tab the Autoconfiguration is set to off. So this UPD driver really has no idea what kind of printer it is trying to drive so of course its going to error out. Switch the autoconfiguration to update now and waaaalaaaaa. Rule of thumb is any time you use any Universal Driver you need to make sure the driver detects the device and its features if you want the driver to work correctly.
