Introduction
The HP Color LaserJet 2500 series printer is a four-color laser printer that prints at 16 pages per 
minute (ppm) in black and white, and 4 ppm in color.

Tr a y s—The printer comes with a tray 1 (multipurpose tray) that holds up to 125 sheets of 
various print media or 10 envelopes. The HP Color LaserJet 2500L (base model) is 
compatible with optional tray 2 (250-sheet tray) for standard sizes of paper and optional 
tray 3 (500-sheet tray) for A4 and letter sizes. (Optional tray 2 must be installed in order to 
install optional tray 3.) 

Connectivity —The printer provides parallel and universal serial bus (USB) ports for 
connectivity. The printer also contains an enhanced input/output (EIO) slot for installing an 
optional HP Jetdirect print server card.
Note The parallel and USB ports cannot be connected at the same time.

Memory—The printer contains three dual inline memory module (DIMM) slots. The standard 
64-megabyte (MB) random access memory (RAM) DIMM resides in one of the slots. The 
printer memory can be expanded to a total of 320 MB using 32-, 64-, or 128-MB RAM 
DIMMs. A language font DIMM can be installed in one of the DIMM slots.
