LaserJet Pro 400 M401dne keeps printing @PJL EOJ after each document

[TSPS]

Hello, i have a problem with my printer, LaserJet Pro 400 M401dne. After each printed document printer prints "@PJL EOJ" on the beggining of a new paper. It is a big waste of paper. It comes at the end of  job which is postscript order from the server, even though I didn't find a driver except PCL6 for the printer, it worked parfectly except for that issue,  is there some way to stop printing this message at the end of each job? Thank you for your help.

It's probably due to a driver fault, although it could be a firmware problem.

Difficult to determine which without further evidence & analysis.

Most print jobs generated by standard Windows printer drivers have the following structure:

<Esc>%-12345X@PJL JOB ...
@PJL ENTER LANGUAGE = language

... pages formatted using selected Page Description Language

<Esc>%-12345X@PJL EOJ
<Esc>%-12345X

where:

<Esc> repeserents the Escape character (the character with decimal code 27, or hexadecimal 1B)

<Esc>%-12345X is the Universal Exit Language (UEL) escape sequence

You could perhaps check what your driver is generating by using the 'print to file' option in the Print dialogue (I'm not sure if this works if the print request goes via a server), then viewing the 'captured' print job in the nominated .prn file.

You can open such a file using NotePad and (although most of the file might look unintelligible) you should at least be able to see the opening and closing UEL sequences and PJL commands.

Note that you'd need a hexadecimal editor to see the character code of the Escape character, rather than an application-specific rendering (perhaps omission) of the character.

Thanks for the replay.

but actually I’m not aware of this kind of editing, but I have a Xerox printer with the same problem, and they helped me with an option to deactivate a PJL notification through the printer menu and it worked perfectly, is there any kind of similar option for this printer even thou if available on the driver.

>> ...  deactivate a PJL notification through the printer menu and it worked perfectly ...

Not sure what this might be referring to - was the menu on the printer itself, or on one of the printer driver properties pages?

>> ... is there any kind of similar option for this printer ...

Not knowing the answer to the first question, I don't know how to answer this one.

Perhaps something to do with bi-directional communication and/or consumables (toner, etc.) usage enquiries/reports?
