Printer leasingglossary.

Clear, concise definitions of the key terms in printer leasing, click-charge billing and fleet management. Look up an unfamiliar term here.

Click charge

A click charge is the fee paid for pages printed on a leased printer: each printed page counts as one click. The leasing provider invoices for the page count, usually with separate unit prices for black-and-white and color pages.

Under this model, the customer pays for use rather than buying the printer: a fixed monthly fee for availability, plus a fee per page. The provider handles toner and servicing, so the page price also covers those costs.

Meter reading

A meter reading is the total number of pages recorded by the printer's internal counter. The difference between readings at two points in time gives the page count for that period, which is used to calculate charges.

Most printers keep separate black-and-white and color counters. Readings can be reported by email, queried through SNMP or read manually from the display.

MPS (Managed Print Services)

MPS means managed print services: a provider takes over another organisation's printing infrastructure, from supplying printers to toner replenishment, servicing and usage-based billing.

Printer leasing is a core MPS model. The provider leases the printers, supplies consumables and servicing, and invoices for actual usage measured in clicks.

DCA (Data Collection Agent)

A DCA is a small program that queries printers on the local network and automatically collects meter readings, toner levels and status, usually through SNMP.

A DCA can run on a server, a small dedicated computer or a Raspberry Pi, using outbound connections only. It provides unattended collection across brands without manual readings or configuring each printer to send emails.

SNMP

SNMP (Simple Network Management Protocol) is a standard protocol for querying network devices. For printers, it can retrieve meter readings, toner levels and status when the printer is reachable on the network.

SNMP has several versions (v1, v2c and v3), with encryption available in v3. Printers expose meter readings and toner levels through standard or manufacturer-specific OIDs.

Page price

The page price is the unit charge for a printed page in click-charge billing. Black-and-white and color pages almost always have different prices because their underlying costs differ.

Minimum page count (included allowance)

The minimum page count is the number of pages included in the monthly fee: an allowance the customer pays for even if it is not fully used. Pages above it attract an excess usage charge, providing the leasing business with a minimum revenue.

The minimum belongs to the contract rather than the individual printer. It does not restart after a replacement; the combined page count of the replacement chain is compared with the monthly allowance.

Excess usage charge

An excess usage charge applies to pages printed above the included minimum. Its unit price is often higher than the included page price, because the minimum allowance has already covered the base cost.

Monthly fee

The monthly fee is a fixed amount paid for a leased printer regardless of usage. It covers printer availability and usually includes a minimum page allowance. Usage-based click charges are added under the contract terms.

Printer replacement (replacement chain)

A printer replacement swaps one leased printer for another, often mid-month. Together, the old and new printers cover the month: close and open their meter readings and apply the minimum to the whole chain.

Treating both printers as separate full months would charge the monthly fee and minimum twice. Correct billing treats the replacement as one continuous chain.

Coverage (5% reference)

Coverage measures the percentage of a page covered by toner. Toner capacity is commonly stated at 5% coverage, roughly a typical text page. Pages using more toner reduce the number that a cartridge can print.

The catalogue page yield is therefore a reference figure. Graphic-heavy or highly colored pages use up a cartridge in fewer pages than plain text documents.

Toner yield

Toner yield is the estimated number of pages a cartridge prints at 5% coverage. The manufacturer supplies the figure, which is used to plan consumables costs and calculate toner cost per page.

Drum unit

The drum is the photosensitive cylinder in a laser printer that transfers the image to paper. It is a wear part separate from toner, usually with a longer service life. Replacement is part of regular maintenance.

Fuser

The fuser fixes toner onto paper using heat and pressure. It is a wear part replaced after a specified page count, often as part of a maintenance kit. Declining print quality can indicate wear.

Maintenance kit

A maintenance kit contains wear parts, usually a fuser and rollers and sometimes a drum, replaced together at the manufacturer's specified page count. It provides preventive maintenance before wear leads to faults.
