If there is a conflict among paper source, size, or type, and you choose to keep the
conflicting size or type setting, then the paper source must be Tray 1, the multipurpose
tray, which can handle any supported paper size or type.

based on media dimensions.

This drop-down list shows all the paper types supported by the HP Color LaserJet 4550
printer, as well as any user-defined types created by a printer administrator. The default
setting is Auto Select, which allows the printer's firmware to select the paper source.
There is no mechanism for manually adding custom paper types from the driver; these
can be added only via the bidirectional communication mechanism (bidi), so they must
already exist in the printer when the bidirectional query occurs. If bidi is working, then the
information returned is an updated list of paper types. If bidi is not working, then the
driver looks for custom paper types saved from a previous bidi query, and uses those (if
any). Otherwise, no custom paper types is accessible through the driver.
The standard types that appear in the lists are:
• Auto Select
• Bond
• Cardstock
• Color
• Labels
• Letterhead
• Plain
• Preprinted
• Prepunched
• Recycled
