Layout Sheets not printing to scale

[Anonymous]

I am using HP DesignJet 510 and printing at 36 x 24. I measure the dimensions on the layout sheet in ArchiCAD and all is fine. When I print the scale is slightly smaller. A line that should be 6" is printing at 5 11/16". I have margins set to zero, Source is Entire Layout, Fit to Page 100% and am using Layout Margin.
Does anyone know what the problem could be?

I'm grateful for all the advice. If I print as a pdf it still prints too small. I'm taking a pdf to our local printer today to see if it is my HP Designjet 510 that is causing the problems. If it is, the HP tech will be coming here to fix & calibrate the printer.
Thanks again!

I just spent an hour on the phone with a HP tech that installed new driver for the printer. Seems that in the process of upgrading to Mavericks something no longer worked properly. Thanks to everyone for all your advice. It was not an ArchiCAD problem at all! If anyone out there upgrades to Mavericks and has the same problem I hope this thread will be helpful.

I spoke too soon. After trying for two hours to load the correct drivers for the Design Jet 510 for Mavericks the tech from Hewlett Packard still cannot solve the problem. He says Apple has not supplied printer driver for Mavericks as yet. I'm considering going back to the previous OSX operating system. I'm wondering if anyone else is having this problem?

I am having the same problem. From the 'net it seems to be a Mavericks issue which isn't getting fixed as quick as it should I wish I could rewind the OS but as a newcomer to Apple I'm a bit stuck. What is really annoying is I moved OS because Win 8.1 looked a nightmare. Now I need to keep my old pc alive just so I can print to scale...

I've been away a while so I haven't posted the information I received from HP.
It seems HP has not provided the driver for the HP DesignJet 500 because it will become an obsolete model. My solution has been to delete Mavericks and go back to the previous OX operating system which I will have to use until the printer dies. if anyone else had this problem I would like to know & maybe my problem will help someone else in a similar situation.
