It's hard to tell exactly what that comment means, but it appears to indicate that this change may be necessary to make the driver work with the printer. It won't affect the printer's speed. Did you also read the earlier comment on that same page? "Works smooth with Kernel 2.6.x. But the printer only talks USB 1.1 (12mbit/s). Apart from that, its postscript engine is slow." > So I could suppose > that "high speed" option was disabled by developers because important > reason. Disabled by developers at HP.

Besides, why would you want to set it up if it gives lots of errors? Remember, the speed at which a device communicates is determined by the device. The kernel has nothing to do with it.
