Weird issue printing on an HP 3540

My 10 year-old Epson printer died and I got a replacement form HP - a deskjet 3540 series, pretty cool printer.
But my happiness didn't last. To my BIG surprise, I couldn't get a score properly printed from Notion! How could this be possible? Is it possible there's something wrong in the Notion side?
The picture below shows a print I did to a PDF file (via Adobe PDF) and then used Adobe to print to the printer.
The score at the right was printed directly from Notion. All bars (repetition, double bars, simple bars) seem scaled up!
What can I do? I found no settings in the printer software that fixes this. I am using Windows 7 64 bit and Notion 4.0.329 32-bit. The only workaround is to print to PDF instead of printing from Notion.
