Laser Jet Pro M402n won't print on my profile

[dsimcox]

I purchased the Laser jet Pro M402n about 2 months ago. It's a fantastic printer - but I'm unable to print while logged into my Mac user account. My wife can print just fine. And if I print from my MacBook Pro in the basement (on my user account) it works great. It also prints from my iPhone with no problems. But when I try to print from my Mac on my user account - it prints two pages - one with this text:

@PJL SET COPIES = 1

@PJL SET JOBID = 61

and another page with this text:

Untitled"

     @PJL SET USERNAME = "del

             "

                      @PJL SET RESOLUTION = 600

                                  @PJL SET BITSPERPIXEL=

And that's it!

I just removed the HP printer folder, reset the printing system in Preferences, and downloaded and installed the new HP Easy Start driver - and this is the result.

Any suggestions would be very much appreciated.

Here's the configuration page, it that's any help:

The fact that those PJL commands are being printed as text (rather than being 'executed' by the PJL interpreter in the printer) implies that the printer has not entered PJL mode.

PJL mode is entered when the device receives a Universal  Exit Language escape sequence:

<Esc>%-12345X

where <Esc> represents the non-graphic Escape control-code character (the character with decimal code 27, or hexadecimal 1B).

The UEL is normally the first few characters of the print job generated by a driver, and should be immediately followed by the required PJL job-level commands.

The implication is that the sequence is not there (or is perhaps corrupt: e.g. missing the opening Escape character).

I'm not familair with Mac systems, so I'm not qualified to advise on whether this is a driver deficiency, or due to something corrupting the job between driver and device.
