I am have a problem with printing in a true scale 1:1. The problem shown when I print a long sketch of (1.5 - 4m). For instant, if I print sketch of 1.5m then I got 5mm extra long. This extra long increases if I print longer sketch. It seems that the extra long has 0.3% (which it less than 1%).
I did many investigations to fix issue but still same. I had contact with HP care center (Because I am using DesignJet 920T printer). HP services are sure that is not printer issue.
My question is: did you experience same problem before? Is there any real solution?
