I am having issues printing out electrical schematic drawings

[Captain7W]

Hi

Each time i try to print my schematics are printing out blurred, i have calibrated the printer, and it only affects SEE electrical schematics. 

Do i need to change the driver ?

Are you printing on A3 or A4 paper size? Strange print quality when printing on A3 is caused by wrong print driver, while it prints fine on A4.

Hi

i am printing on A3, 

I transferred the documents to my old lap top, they printed fine from there. 

I think the Driver is PCL-3

Compare print driver versions on 2 laptops, the old one is running a HP driver, while the new one is running Microsoft drivers. Go to hp.com and install latest HP drivers, don't use Microsoft drivers, that will solve you printing on A3
