T930 not printing to scale

[Teester]

I have a construction business and use this machine to print drawings, from which I use a scaler to roll off distances which are then put in the computer which prices the work.  For example a plan sent to me shows a 1/4' scale, ie  4 feet = 1 inch on the plan I print, or should be.  

Currently what should be one inch is printing it in roughly 15/16's of an inch.  An 80' distance is actually measuring 75.70' or about 95% of the actual distance.  That 5% error COSTS ME 5% more in labor and materials expense.  I just learned my plans were not printing right on an Autozone job I did, which we went over budget on!  

When I click print, the dialog box that pops up shows print options of Fit, Actual Size, Shrink Oversize pages or Custom Scale with round Select buttons, then a square Select button below which says Choose paper source by PDF paper size.  

I've been using Actual Size.  I tried the "Choose paper source..." box and it didn't even print the complete page, as if it had ran out of paper.  

Support online is not available at this point so that's how I came about this page.  
Any help would be appreciated.

Hi,

do you print PDF Files ?

When printing using the Adobe Reader,

- do not use `paper source by PDF paper size'

- Use "print actual size"

- select the paper size manually

Check with your Business-Partner, IF the PDF actually IS made to scale!

When creating a PDF from CAD it may happen, that the user is using a fitting papersize but missing the margin.

Then it happens, that the "printed" PDF has 98% or 95% or less of the correct size.

TIPP:

Use the "HP Click" Printing Utility.
