Our take
Lexmark's support record identifies the Optra E310 as a black-and-white laser printer for printing only. The official guide describes an 8-page-per-minute engine, 2 MB of standard memory with expansion options, a 150-sheet automatic feeder, and a single-sheet manual feeder. Its rear panel shows USB and parallel connections. Those are concrete facts for a narrow, old-model use case, but the reviewed materials do not state a recommended monthly range, standard Ethernet, wireless networking, or automatic duplex. It should be considered only when a buyer can match the exact machine and its connection to a real setup.
A buyer who specifically needs the Optra E310 identity, has a compatible direct connection, and can verify software support for the intended computer..
It is not a fit for a modern shared network, fast office queue, automatic duplex requirement, or buyer who needs documented current operating-system compatibility.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark's official support page classifies the E310 as a monochrome laser print-only printer.
- The guide lists USB and parallel ports, a 150-sheet feeder, and a one-sheet manual feed.
- The manual provides model-specific troubleshooting and paper-loading instructions.
What to weigh up
- The published maximum speed is 8 ppm, much lower than modern office models.
- The checked source set does not document Ethernet, wireless networking, standard duplex, or recommended monthly volume.
- The original manual covers older computer systems, so present-day driver fit must be verified separately.

What the features mean for you
Use the E310 identity, not its E312 neighbor
Lexmark's support page names the Optra E310 and classifies it as a laser, print-only, black-and-white printer. The Lexmark-issued user guide also explicitly describes the E310 in its model-specific text. The fact that the same guide family mentions other printers does not make their features interchangeable. Confirm the E310 name on the machine and use the exact support material when checking it. A historical listing or a generic Optra E-series title cannot establish a newer interface, speed, or accessory that belongs to a different model.
Expect a modest rated pace
Lexmark's guide says the E310 prints up to 8 pages per minute. That is a useful limit for planning occasional forms, short notes, or simple black documents, but it is far below the rated speeds of modern small-office laser printers. The rating is not a measurement of a particular used unit, and complex jobs may take longer. It is better treated as a reason to keep the printer in a low-volume role than as a promise that every job will finish at that pace. A busy office should choose a model with a higher documented engine speed.
Understand the paper path
The guide specifies a 150-sheet automatic paper feeder and a single-sheet manual feeder. The feeder handles routine stock, while the manual path lets a user present one sheet or special media separately. This arrangement can work for a simple desk printer, but frequent multi-page jobs may require more refilling than on a larger tray-equipped model. The manual describes loading and paper handling, not the condition of an individual feeder. Inspect rollers and test a full stack before relying on an old unit for repeated work.
Connect directly and verify the computer
Lexmark's guide shows USB and parallel ports on the printer. Those are direct connections; the checked source packet does not establish Ethernet or Wi-Fi for the standard E310 configuration. A parallel connection may require older hardware, while USB still needs a suitable driver and cable. The manual's original driver instructions concern older operating systems, so it does not promise compatibility with a current computer. Check the exact computer, driver source, and connection before purchasing rather than assuming that a USB plug alone guarantees setup.
Keep duplex and workload as unknown
The sources reviewed for the E310 do not specify an automatic duplex unit or a recommended monthly page range. That means the finder should not match it to a required automatic two-sided workflow or assign it a numeric monthly tier. The manual's printer-feature overview and specifications are the evidence available here; a maximum duty figure from an unrelated Lexmark model would not fill the gap. A buyer who needs automatic page turning or regular high-volume service should choose a model with those exact features documented. For an occasional direct-connected task, the unknowns can be acceptable if they are not must-haves.
What else to compare
The Canon imageCLASS LBP226dw is a newer documented mono printer with Wi-Fi, Ethernet, automatic duplex, and a 750–4,000-page recommended range. Choose the E310 only when its exact legacy model and direct connection are specifically useful.
Before you buy
Is the Optra E310 a laser printer?
Yes. Lexmark's support record classifies the exact Optra E310 as a black-and-white laser print-only printer.
Which connections does the official guide show?
The guide identifies USB and parallel ports; it does not establish standard Ethernet or Wi-Fi for the E310.
Does the guide give a recommended monthly workload?
No comparable recommended monthly range is stated in the reviewed E310 source packet, so workload fit remains unknown.

The decision
The E310 is a verifiable but limited legacy printer. Buy it only for a direct-connected, low-demand role after checking the computer and hardware condition.
