Our compatible HP Q5945A toner cartridges are guaranteed to meet or exceed the factory cartridge specifications, and are backed by our Lifetime Cartridge Warranty.

A multifunction machine still needs just one toner cartridge when it is monochrome, and for the LaserJet 4345MFP that cartridge is the HP 45A (Q5945A). Printing, copying and faxing all draw from the same black toner supply, and every 4345 configuration — the base LaserJet 4345, the LaserJet 4345MFP, the extended LaserJet 4345XMFP builds — accepts the identical unit. With no high-yield 45X in existence, high-volume sites manage supply through stock depth: keep a spare 45A on hand and the busiest machine on the floor never goes dark. Clever Supplies lists the 45A as the genuine OEM HP cartridge and as a compatible, so facilities choose between factory original and budget equivalent. One cartridge, four functions, zero downtime.

Frequently Asked Questions

My 4345MFP copies and faxes too — does the 45A cover those, or do I need other supplies?

The 45A covers everything. The 4345MFP is a monochrome machine, so printing, copying and faxing all use the same black toner cartridge. One 45A (Q5945A) is the printer's only consumable.

Do compatible 45A cartridges work with the 4345MFP's chip authentication?

Quality compatibles include a compatible chip that the 4345MFP recognizes, so the printer accepts the cartridge and reports toner levels normally. The genuine HP 45A uses HP's original chip; reputable compatibles replicate that handshake reliably.

The 4345MFP is our busiest machine — any tips for managing 45A supply?

Because there's no high-yield 45X, high-volume sites manage supply by stocking depth rather than cartridge size: keep at least one spare 45A on hand at all times. When the printer's low-toner warning appears, you typically still have a comfortable window to swap in the spare before output degrades.
