sorry to get back so late, but this user only returned today to the office and we've tried your suggestion and unfortunately we didn't found some options you've mentioned.
We managed to solve this thing out with a driver reinstalation and everything got back to normal.
Thanks for your support.
Thank you for using the Support Forum. Please make sure that the driver is not set on the draft mode. Here are the steps to check on the draft mode.
If the draft mode is off then please consider contacting your support centre for further assistance.
I have one laptop, windows 7 x64, and using the same driver everyone uses for a Xerox Workcentre 7132, which prints in faded whatever in B/W or Colour.
I've checked drivers versions, and they're (still) all the same as the other laptops. Neverless this one started printing in "fade mode".
The printer is on PCL mode and the driver version is PCLXL.DLL vs.6.0.5479.0
Thanks in advance.
