Hi, my HP m451dn (400 series) laserjet printer recently started to switch letters, usually to Polish (I'm Polish too, so that's nice) on certain fonts, i.e. only on those which are monospaced. I print a lot of text in Times New Roman and other serif fonts, but when I print my songbook which I maintain in Courier/Droid Sans Mono it prints it with broken letters. Instead of fis I get fiś, instead of Jezu I get Jezż.
Yesterday I found that if I switch font to Consolas I get correct letters. I think this might be due to text being sent to the printer without font, but common substitution of Droid Sans to Courier Postscript happens, but I can't find an option to turn it off. Do you think this is broken memory, or maybe I should reflash it? I googled a lot of hp support pages, but nothing found
