In general, for PostScript you *must* have enough memory to hold an entire
page worth of bits.  The LaserJet firmware converts characters (etc.) to
bits on the fly as the paper goes through, but PostScript can't do that.

A megabyte is marginally adequate to hold an 8.5x11 sheet, but you need
some extra for work area, so 1.5MB is the working minimum.  Make that
2MB for legal-size paper.  In general, more is better, especially for
complex PostScript.  The dealer who's selling you the cartridge should
be able to tell you how much memory it needs.
