Our take
HP identifies the Color LaserJet CP4005n as a color laser printer rated up to 30 pages per minute in black and 25 in color. Its U.S. support page lists a 2,000–7,500 recommended monthly range, standard USB 2.0 and Fast Ethernet. Wireless is optional through an external print server. The reviewed exact source does not establish automatic or manual duplex, so the profile keeps both fields unknown. Compared with the Brother HL-4040CDN, the CP4005n has a higher stated color speed and a published workload band, while Brother's exact spec confirms automatic duplex and the HP source does not. Choose by that practical difference rather than assuming the same paper handling.
A wired office that needs faster color output and a published workload band, while duplex is not a must-have..
Skip it if automatic duplex is mandatory, built-in Wi-Fi is needed, or an integrated copier/scanner/fax is part of the workflow.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP rates color output at up to 25 ppm and black output at up to 30 ppm.
- The manufacturer recommends 2,000–7,500 pages monthly.
- Standard USB 2.0 and Fast Ethernet are documented.
What to weigh up
- The checked exact-model source does not settle automatic or manual duplex.
- Wireless relies on an optional external print server.
- It is print-only and does not document copy or scan functions.

Full review: how the features affect your choice
What the features mean for you
A color print engine for wired offices
HP identifies the CP4005n as a color LaserJet printer with standard USB 2.0 and Fast Ethernet. It is a print-only model rather than a multifunction device, so copy and scan work will need separate equipment. The built-in Ethernet route can serve a wired queue without an optional server card, which is useful when several users need access. Inspect the actual network port and confirm driver compatibility for the computers in use. The exact HP support page is the source for the model identity and specifications ([HP CP4005n U.S. specifications](https://support.hp.com/us-en/product/product-specs/hp-color-laserjet-cp4005-printer-series/2512209)).
Black and color speeds are separately rated
HP lists up to 30 pages per minute for black output and up to 25 for color. Keeping those ratings separate helps a buyer compare jobs dominated by text with those that use color. These are manufacturer specifications, not observed results from a particular printer or a guarantee for every file. A complex document or aging device may behave differently. The CP4005n has a higher listed color rate than Brother's HL-4040CDN, while the Brother's verified duplex path gives it a different advantage. Choose based on the task mix and the exact setup rather than one speed number alone.
The workload band provides planning context
HP recommends a monthly range of 2,000–7,500 pages for the CP4005n. That band is more useful for workload matching than a maximum duty-cycle figure because it describes the maker's recommended operating volume. A small office with regular color output can use it as one planning input; a team below or above the range should compare models with a better documented fit. This recommendation does not promise that a used printer will perform at a particular speed or remain trouble-free. Check service history and consumable state before assigning it to sustained office work.
Duplex remains an unanswered question
The reviewed HP model source does not establish automatic or manual duplex for the CP4005n. The profile leaves both values unknown. Do not assume two-sided hardware from the CP4000 series name or from a picture that may show a different sibling. If automatic duplex is a hard requirement, ask for an exact manual or inspect the offered printer for the accessory and test it. The Brother HL-4040CDN is a useful contrast because Brother's U.S. page explicitly lists an internal duplex unit. That documented difference can be decisive for offices that print double-sided documents every day.
Optional wireless is not standard Wi-Fi
HP lists wireless print servers as optional connectivity, while its standard connection list includes USB and Fast Ethernet. A buyer should not treat the optional accessory as already installed. Confirm its exact part number and compatibility if wireless placement matters; otherwise plan around the documented wired port. Optional hardware and current driver support should be checked on an older printer before making it part of a network. The model's fast color rating and monthly recommendation remain useful comparison points, but the exact connection package on the offered unit controls how it can be used.
Compare for your needs
For confirmed duplex compare the Brother HL-4040CDN; for wireless choose a model with standard Wi-Fi or verify an exact compatible HP print-server accessory.
