Two-sided printing

Automatic duplex; Gigabit Ethernet and USB

A printer for a wired output queue

Canon's U.S. support page describes the LBP6780dn as a black-and-white laser printer. The model name and suffix are important: the dn version is the network-oriented configuration in the candidate. Canon lists Gigabit Ethernet and USB, making it suitable for an office network or a direct workstation. It does not include copy or scan functions. If an office needs to digitize signed pages or duplicate originals, retain a separate all-in-one rather than expecting this print engine to handle paper intake.

Rated simplex and duplex speeds

Canon gives separate Letter ratings: up to 42 pages per minute for one-sided output and 20.5 pages per minute for duplex jobs. The figures allow a useful comparison with printers whose two-sided speed is lower, but they are manufacturer ratings, not a guarantee for complex files or a specific aging unit. Automatic duplex can reduce manual handling for long reports and internal handouts. If a used printer is being considered, request both a single-sided text sample and a duplex sample to check alignment, feed, and image quality.

Keep the missing workload number missing

Canon's exact U.S. support page lists a maximum duty-cycle value but does not provide a comparable recommended monthly page range. A maximum describes an upper operating limit under specified conditions, not the routine level Canon recommends for long-term use. This review therefore leaves both monthly endpoints unknown. The printer's high rated speed is also not a substitute for monthly guidance. If a procurement rule requires an explicit recommendation, compare another model with a published range rather than inferring one from speed or duty cycle.

Check the network and optional-feature assumptions

Canon lists Gigabit Ethernet and USB for the LBP6780dn. The reviewed page does not establish built-in wireless networking, so a wireless-required choice should not include the model on the strength of a generic listing. Verify the rear-panel ports and exact nameplate, especially where used and refurbished inventory may combine family accessories or descriptions. A network port is useful only if the office can support the printer's drivers, firmware, and security posture; legacy hardware may need a more careful compatibility check than a current device.

Paper path, maintenance, and the separate MFP

The LBP6780dn is best assessed as a dedicated print engine. Check the paper trays, rollers, duplex path, internal condition, supplies, and service history. Canon's page can establish what the model was designed to do, but it cannot confirm the state or included toner of an individual listing. If the printer is going into a shared location, make sure a separate copier or scanner is available and that its workflow is acceptable. Ask about return coverage and test network printing from the intended computers before relying on it.

Match the output needs before buying older hardware

For an office seeking fast mono output, automatic duplex, and Ethernet, the LBP6780dn has a specific and well-documented profile. It is less complete than an MFP, and the absence of a recommended monthly range limits workload comparison. A Lexmark E260dn offers a lower speed rating but a documented 250–2,500 page recommendation. The HP P2055d adds a 750–3,000 range but is not the same Ethernet-equipped dn configuration. Choose Canon when throughput and wired networking matter most, while checking supplies, drivers, and exact unit condition.

How the alternatives change the decision

For Ethernet with a known 250–2,500 page recommendation, compare the Lexmark E260dn. For copy, scan, fax, and duplex document handling, compare the Xerox WorkCentre 3550.

The product suffix changes the connection story

HP's materials distinguish the P2055d from the P2055dn. This review follows the candidate's exact P2055d name and CE457A code. HP's product guide identifies USB and parallel connectivity for that model, while its dn variant adds Gigabit Ethernet. A generic listing that mixes those suffixes can lead to the wrong network expectation. Check the nameplate and rear ports before planning an installation. A separate print server could be considered only after verifying compatibility; it is not a built-in P2055d feature.

Fast monochrome output with automatic duplex

HP rates the P2055d at up to 35 pages per minute for Letter-size pages and documents automatic duplex. That combination is suited to office text and multipage materials where the printer can turn sheets without manual refeeding. It remains a rated maximum rather than a guarantee for a complex document, first page, or aging machine. The automatic duplex mechanism should be checked with a sample from any used device. Color printing is not available on the monochrome model, and the feature list does not include a copier or scanner.

Paper handling supports more than a small desk queue

The U.S. guide identifies a 250-sheet Tray 2 and a 50-sheet multipurpose tray. The smaller path can accept a different stock or size without replacing the everyday paper in the main tray. That is a practical setup for a modest shared office, though it is not as expandable as some workgroup machines. Ask whether the advertised printer includes the standard trays and inspect paper guides and feed rollers. A tray count does not translate directly into an advised monthly volume.

A published volume band, with limits

HP's U.S. support specification recommends 750–3,000 pages per month. Buyers can compare that band with their ordinary printed volume, but it is not a duty-cycle maximum, lifetime estimate, or promise that every unit can sustain the upper endpoint after years of use. It also does not supply present toner cost or condition. If expected monthly work regularly exceeds the guidance, compare a heavier-duty model. For a lighter routine, a newer smaller printer may be more convenient to support even if its speed is lower.

Plan for an older direct-connect device

The P2055d is a legacy platform. Before deployment, check whether HP's driver path supports the actual computers and whether parallel connectivity is relevant or a USB connection is sufficient. Verify the CE457A label, inspect the duplex path and rollers, and request a recent text sample. Find out what toner is installed, whether supplies are included, and what return coverage applies. An exact-model search link is not a statement about present availability, seller reliability, stock, or condition. The named historical ASIN is not used as a purchase link because the exact current offer is unverified.

Choose it only when the wired setup fits

The P2055d fits a buyer who wants fast monochrome output, automatic duplex, and an HP-published monthly band, while accepting direct USB or parallel use. If a wired Ethernet port is mandatory, select a model whose exact suffix documents it, such as the Lexmark E260dn or Canon LBP6780dn. If wireless and higher throughput are priorities, Lexmark's B2865dw is a different workgroup tier. The P2055d's strength is the specific feature and volume combination, not a broad promise that it suits every P2055 family listing.

How the alternatives change the decision

For standard Ethernet in a mono print-only model with a published monthly recommendation, compare Lexmark E260dn. For a faster networked workgroup model with Wi-Fi, compare Lexmark B2865dw.

Model covered

B2865dw

Main functions

Monochrome print-only output

Print output

Up to 65 ppm Letter; automatic duplex

Two-sided printing

Wi-Fi, Gigabit Ethernet, USB; 5,000–75,000 pages monthly

Built around a large shared queue

Lexmark classifies the B2865dw for a large workgroup and gives it a recommended monthly range of 5,000 to 75,000 pages. That is a meaningful operating boundary rather than a promise that every month should reach the maximum. It suggests a different role from a compact desk printer: several users can send monochrome jobs to a centrally placed device, while administrators plan supplies and maintenance against a substantial workload.

Fast Letter output with automatic duplex

The U.S. specification rates the B2865dw at up to 65 pages per minute on Letter and lists integrated duplex. Lexmark gives a separate duplex speed, which reflects that two-sided work is not the same as simplex throughput. Automatic page turning can reduce paper use without requiring an operator to re-feed a stack. These manufacturer ratings describe the model, not the result from an older unit with unknown maintenance or supplies.

Network options are standard on the exact part

Part 50G0900 includes Gigabit Ethernet, USB, and 802.11b/g/n wireless. A wired administrator can use Ethernet while nearby users print through the managed network; USB supports local setup or direct attachment. Confirm the actual unit's ports and wireless configuration before deployment, especially where an older printer will join a current security environment. Optional network cards on related products do not need to be borrowed here because this exact U.S. page lists wireless standard.

Paper handling can grow, with a cost in space

The base arrangement includes a 550-sheet input tray, a 100-sheet multipurpose feeder, and a 550-sheet output bin. Lexmark lists optional drawers, high-capacity trays, output expanders, and finishing accessories. This breadth can reduce refill interruptions or support a more organized department workflow, but an offer may not include every pictured option. The base unit is already large and weighs 56 pounds, so plan its location and transport before buying.

It is a printer, not an all-in-one

The B2865dw supplies monochrome printing but does not add the copy, scan, or fax workflow of an MFP. That can be an advantage when the office already has separate scanners and needs a focused output engine. It is not a substitute for a paper-capture device. Match the device to the actual office layout rather than treating a high print speed as a reason to buy functionality that the model does not provide.

Confirm the exact build and service path

Lexmark identifies B2865dw part 50G0900 and notes that replacement cartridges are region-specific. Check that part number, tray count, duplex operation, network ports, imaging unit, and toner match the offer. Review the seller's return terms and verify current operating-system support with Lexmark before placing the unit on a network. A high-capacity specification cannot establish the history or remaining life of an individual used printer.

How the alternatives change the decision

Choose Lexmark E260dn for a smaller mono network printer with a 250–2,500 page recommendation. Choose Canon imageCLASS LBP6780dn for a fast wired mono model with an unknown monthly range.

Two-sided printing

Automatic duplex; USB, parallel, and Ethernet

A focused mono print role

Lexmark describes the E260dn as a monochrome printer rather than an all-in-one. That keeps the device's purpose clear: it produces office documents but does not replace a separate scanner, copier, or fax machine. For a desk that already has those tools, a print-only model avoids paying attention to functions that would sit unused. For a shared department that handles signed originals or incoming faxes, the narrower role may be a reason to select a different product. The maker's exact part identifier, 34S0300, helps separate this wired dn version from related E260 family names.

Automatic duplex is a meaningful convenience

The product page lists integrated duplex, so a two-sided print job does not require the user to remove and reinsert pages between passes. This can reduce handling for policies, multi-page handouts, and internal reports. The feature is print duplex; it says nothing about scanning or copying because this unit has no document capture path. A used printer should still be checked with an actual duplex page sample, since manufacturer features do not establish the condition of a particular mechanism. If single-sided jobs dominate, the duplex unit may add little to the decision.

Wired ports and simple paper handling

Lexmark lists Ethernet, USB, and parallel connectivity. Ethernet can place the printer on a local wired network; USB supports a nearby computer; and parallel may matter where older equipment remains in service. Wi-Fi is not part of the documented standard interface set. The 250-sheet main tray and one-sheet feed are adequate for everyday paper changes but smaller than office models designed for long unattended runs. Ask whether the offer includes the standard tray and inspect the feed path rather than assuming accessories from another E260 listing are present.

Use the recommended range carefully

Lexmark publishes a recommended monthly volume from 250 to 2,500 pages. This is a guide to a suitable operating band, not a guarantee of toner cost, speed on every document, service life, or a seller's page count. The 35 ppm rating is likewise a rated output figure rather than a measure of how much work the printer should handle monthly. For expected use near the top of the band, compare current consumable availability and consider how frequently the small tray would need refilling. Do not substitute a maximum duty-cycle figure for this recommendation.

Check support and the exact suffix

This is an older model, so compatibility can be more important than a long feature list. Confirm the host operating systems, driver path, Ethernet negotiation, and any print server requirements before choosing it for a managed network. Ask for a label photo confirming E260dn and part 34S0300, not merely E260. Inspect the drum and toner, rollers, paper tray, output, and duplex path; request a recent print sample and clarify return coverage. The exact-model Amazon search is only a discovery link and makes no claim about availability, condition, or included supplies.

Choose it for predictable wired pages

The E260dn makes sense when the job is limited to black-and-white output, the network is wired, and automatic two-sided printing is useful. Its published monthly range provides a threshold for comparing small-office workloads, while the basic paper arrangement avoids an oversized feature set. The alternatives in this batch have different roles: an HP P2055d is faster and has a larger multipurpose feed but remains without Ethernet; a Lexmark B2865dw is much faster and supports wireless networking for a heavier workplace. The right choice depends on whether the E260dn's smaller operating band matches the actual routine.

How the alternatives change the decision

For faster high-volume mono output with wireless, compare the Lexmark B2865dw. For copy, scan, or fax, choose an MFP such as the Xerox WorkCentre 3550 rather than this print-only model.
