Comment 75 for bug 277404

I've found Ubuntu (via the Launchpad Ubuntu bug), as well as the Windows HP driver seems to be forcing HP product (M1522NF here) to use PS Level 2, even though PS Level 3 is specified.

In other words, you can explicitly state within the application to print PS Level 3, but you'll get a rendered PS Level 2 file instead without you knowing it. I kind of complained this is "hackish" to the Ubuntu Launchpad filed bug. At most, the box should be greyed or unavailable for these products that do not support PS Level 3.

On Gentoo here, cups printer support is setup to obey the user's configuration files -- as well as probably most others except Ubuntu. I've made note of the PS Level 3 printing problems for HP products known on Gentoo Wiki.

(Also note, irrelevant to this bug, using a the HP M1522NF fax plugged into a phone outlet using DSL with a DSL filter, the fax modem on this device seems to misinterpret the DSL signals as a fax signal sometimes, and you'll hear noise through the HP product speaker. Hard reset is the only cure, aside from also unplugging the phone/fax line when you're not using it.)
