What is an advantage of PCL 6 over PCL 5c?

Question

Options

• APCL 6 supports color printing and PCL 5c does not.
• BPCL 6 is compatible with all PCL printers and PCL 5c is not
• CPCL 6 can use object-based commands instead of only HPGL commands.
• DPCL 6 has improved paper handling functions

• A
  16% (6)
• B
  3% (1)
• C
  74% (28)
• D
  8% (3)

Explanation

PCL 6 introduced an object-based graphics model (via PCL XL), which allows the language to describe graphics and text as high-level objects rather than relying on older command sets. This makes rendering more efficient, especially for complex graphics and scalable fonts.

Why the distractors are wrong:

• A is incorrect because the "c" in PCL 5c literally stands for color - color support already existed in PCL 5c.
• B is incorrect because PCL 6 actually broke backward compatibility with older PCL hardware; it required newer printers, not fewer.
• D is a plausible-sounding but unsupported claim - improved paper handling is not a documented primary advantage of PCL 6.

Memory tip: Think of the "6" as stepping up to a higher level of abstraction - PCL 6 = objects (like object-oriented programming), while PCL 5 stayed closer to low-level commands. If you remember that PCL 5c already did color, you can eliminate A immediately, which leaves you to focus on what was architecturally new in PCL 6.
