Cannot print CAD drawing PDFs on HP DesignJet 4000 since version 3.4+

[mfvescovi]

Preamble: I've already tested pre-release build and the issue persists.

An annoying problem on printing CAD drawing PDFs (mainly on ISO A1 and ISO A0 formats) started occurring since the upgrade to v3.4+ (Windows 10 64 bit, testing both installer and portable). Following, the dialog I got as output of SumatraPDF on starting printing:

For the sake of testing, I've downgraded to v3.3.3 and the issue disappears on the same PDFs v3.4+ failed to print. On any other application, the printer works as expected.

Thanks for your efforts in fixing this problem.
