I'm having the same issue i get the following error message on my printer "data violation pdl request 016-720".

My printer is a Dell 3110CN. My setup is a Dell Precision T 3400 running Vista Ultimate 64 bit. I also have a Dell T605 server running Windows 2008 Server 64 bit in this network as well as one Windows Vista Ultimate 32 bit machine and  2 Windows XP Professional machines. The Dell T605 and 32 bit machines are still able to print with the PCL driver (the server serves as print server as well). All available MS updates have been installed. Turning off Symantec AV has no effect on the issue.

The only machine affected is the Dell Precision T3400. Whether installing the driver using the print server or installing the driver locally on the Precision the results are the same (I'm using the latest Dell Provided Driver). It is not a network issue as I have installed the PS driver and the printer functions as expected

No solution, but this sounds like we may want to get the forum moderator to escalate this.

It appears that both machines (3010cn & 3110cn listed in the thread) have problems printing from Vista 64-bit platforms. Gotta love Vista..... NOT !!

PDL means Page Descriptor Language. If you get PDL errors, it generally means the PDL code provided to the printer has a problem.

As a possible workaround, can you "share" the printer from a working platform?

I have been experiencing the same issue.  I receive the same pcl error code(016-720) but I'm using Vista-32 bit and the 3115cn.  Has any one found a solution to this?

I've had the same problem for some months with my 3110cn, hooked up to a HP desktop running Vista 32.

Around December I found that any print run over about 10 pages (MS Word, pdf and Publisher files) would give this PDL error - sometimes immediately, sometimes after a dozen pages.  Rarely would the print run succeed beyond 15 pages at a time.  The symptoms became worse as time went on so I called tech support.  The tech guy did something with my drivers via Dell's remote takeover, so I couldn't follow what he was trying to accomplish.  It seemed to clear up the problem for the next week, but since then it has been returning in the same progressive way that it did before in December:  long print runs more and more frequently produce an error, and often even printing a one-page document will return the error two or three times before finally printing.

Given the inconvenience of this error in printing multiple copies of a document, unless Dell figures this one out and produces a solution I will have to scrap this printer and buy a different brand ASAP.  It is virtually non-functioning as a multi-page printer.

Since you're running Vista, another thought has occurred to me. You may want to try using the XPS Document Writer function included with Vista (it has to be specially setup on an XP system)

Check to see if you have the XPS Document Writer listed as a printer object. If so, "SAVE-AS" your document, choose "PDF or XPS", name your file and choose the .XPS extension, then click "Publish".

To print; locate the saved file and dbl-click. The file opens in an IE window; click File, Print, choose your printer, then click Print. (or use the printer icon located on the IE tool-bar)

If you haven't tried it, give this a shot. I've been able to print some VERY large files to printers using this method that would normal make the printer "throw-up".

Well..... it "might'a could'a" worked.....

Do you get the exact same error using the XPS method?

I just tried this XPS idea for a 45 page document, converted to XPS from Word with a fair amount of greyscale graphics and text.  It delivered the error on all three of my print attempts, although in one case I got through about 15 pages before the machine rebelled.  Thanks for a good suggestion, though!

Yes, the same error:  "DATA VIOLATION PDL REQUEST 016-720".
