Laserjet M451 prints multiple times the copies requested (pdfs only)

[r-g-t]

When I try to print an Acrobat pdf document, the output is multiple times what I request. In fact, it is the number of requested copies squared! Asking for one copy gets one, for two gets four, for three nine, etc. This does not happen when printing from my iPad, but only from my desktops. One uses Mac OS 10.7.5, the other 10.8.5. Both have the same result. Printing word documents, etc. prints correct number of copies.

Hi r-g-t,

I just posted this answer for a very similar problem in the same machine that was reported today and found your unanswered post when I went in to answer that one.  Sorry for long delays.

This is a very interesting problem and I am not sure that this will help, but it is worth a try. 

There is a print copy setting that is in the Embedded Web Service for this machine that is not on the control panel as far as I can find it.  Also, I am working with a slightly newer machine, so all bets might be off.

1.  Open a browser like explorer that is on the same network as your printer, if possible

2.  In the address window for the browser type in the IP address of the printer (this can be found on the configuration page or if you have a touch screen via the network settings system)

3.  once you send the address of the printer, a window should open with the name of the printer across the top and 5 or 6 tabs across the area just below that.

4.  Open the Print Tab and on the left sublist select Printing

5.  There should be a "NUMBER OF COPIES" box with a 1-999 setting allowed

6.  Make sure that the setting is one (1) in that box, APPLY, and then try again.

I am not sure why PDF's would be different than word documents, but since this might be an interaction between drivers and the internal system, anything can happen. 

Even though your progression is not just a number of copies mode, I suspect that since this was supposed to be used instead of putting the number of copies for a print job in the driver, somehow the two numbers are interacting to give your exponential output.  Please follow up and let me know if your number of copies was set to something other than 1, since this is possibly a bug that HP has not seen till now.  Especially if it is new for windows 10.  The Driver setting of number of copies was supposed to override this setting and if it no longer does this others could see a similar waste of toner and paper.

Others at HP asked me what kind of 2016 welcome pdf you were trying to print on New Year's Eve  ((;-)>

Thanks, Dovid

Chiming in with a "me too", but with a LaserJet m452 on Windows 7.  We're using the HP Universal Print Driver (have tried both PCL 5 and PCL 6 versions) and get the same thing across every PC in the org:  If you print 2 copies in Excel, you get 4.  If you print 9 copies in Excel, you get 81.  It's not some random overprint of a few extra copies, it's always the exact square of the number of copies requested.  100% reproducible with either of the latest UPD installations.   We have Xerox printers installed via Group Policy from the same print server and they don't have the issue, it is definitely a problem with the HP driver.  The printers all show just 1 copy in the web interface, so the possibility mentioned above doesn't come into play.

Same issue here.  Only HP printers, multiple laserjet models, multiple OS versions (Windows 7 and 10), and same multiplication of prints - 2 = 4, 3 = 9 and so on.  Anyone get a fix on this???  Desperate to resolve.

Any additional info with this problem. I am also experiencing on 1 of 3 M451-DN Printers. All using Latest UPD.

[TravAU]

I also have this happening with:

P2055

M451

M476

All using latest UPD and firmware on printers. Seemed to only happen after a UPD update in December (unsure of which version as multiple copy printing is not common in this workplace).

I should note this is happening from any program: Adobe, word, notepad...

The multiple copy settings in the printer are all correct, so leads me to believe it is the UPD...

Hi,

Please try to check the 'Mopier Mode' under Devices and Printers -> printer properties (current printer under using) -> Device Setting, if the Mopier Mode is disabled, please enable this setting, then try to see if this issue can be resolved or not.

With this mode enabled, a printer can receive one copy of a document, and print multiple collated copies.

With this mode disabled, the printer must be sent multiple copies of the print document in order to print multiple collated copies.

Let me know if my resolution can resolve your problem.

Same problem here with a NON-HP printer (Brother MFC9340CDW).     So the problem might be in a generic Windows driver.

(Or it could be the same or similar bug re-implemented by other people...)

[TravAU]

Well, it seems the Mopier mode disablement has solved the issue. Can't explain why, but hey, I'm happy now!

I was having issues with a few different model HP printers printing off 4 copies when only 2 were requested in MS-Word. Seemed to be OK in MS-Excel for some reason.

Changing the Mopier settigngto enabled resolved the issue.

Strange but excellent fix.
