The Comparison That Matters for Your Office
I'm the office administrator for a 60-person company. I manage all office equipment and supply ordering—roughly $180,000 a year across a dozen vendors. When I took over purchasing in 2020, printers were the first category I had to clean up, and I've been evaluating them ever since. I report to both operations and finance, so every printer purchase is a balance between "it works" and "it makes financial sense."
This article compares the two paths most offices end up weighing at Epson: the Epson WorkForce Pro WF-4730 wireless all-in-one color inkjet printer and an EcoTank model like the ET-4850. I've bought both types. I've also owned the mistakes that come with both types.
Here are the four dimensions I actually compare when I spec a printer:
- Total cost of ownership—not the sticker price
- Scanner software and daily workflow
- Maintenance and reliability
- Print quality for real business documents
If you're deciding between these two, those are the four things that will affect your team, your budget, and your patience.
Dimension 1: Sticker Price vs. Cost Per Page
"Which one's cheaper?" is the first question I get. It's the wrong first question.
The WF-4730 costs less upfront. As of January 2025, I've seen it listed between $199 and $249 across major retailers depending on sale cycles. The ET-4850 typically runs $299–$349. Those prices move, so verify current rates before you budget.
But I track cost per page, not purchase price. I built a simple spreadsheet calculator that factors in the printer's price, ink costs, and expected page volume over three years. You can do the same in about ten minutes, or use Epson's own cost-per-page calculator if you want a packaged tool.
For a small office printing 500–800 pages a month, my numbers look like this:
- WF-4730 with standard cartridges: roughly 3–4 cents per black page and 10–14 cents per color page.
- ET-4850 with refill bottles: roughly 1 cent per black page and 3–4 cents per color page.
If you print under 300 pages a month, the difference barely matters. If you print more, the EcoTank pays back its higher sticker price within two years. That's the conventional math. Everything I'd read said tank printers save money, but I was still surprised by how fast the gap widened once we started printing color reports weekly. The click costs on the cartridge-based WorkForce Pro add up faster than the marketing sheets suggest.
Dimension 2: Scanner Software and Daily Workflow
This is the dimension I ignored for years because it doesn't show up on spec sheets. It turned out to be the one that affects my day the most.
Scan to PDF sounds identical on every printer brochure. The reality is that the software between the scanner glass and the finished file varies a lot.
The WF-4730 comes with Epson Smart Panel and the full Epson printer scanner software package. I use the scanner almost daily—routing invoices to finance, converting printed contracts into searchable PDFs, and copying documents for the quarterly board meeting. The document feed software auto-detects edges, straightens the image, and produces a searchable PDF in one pass. It's unglamorous, and it saves my assistant and me about an hour a week.
The ET-4850 uses the same core mobile app, but the experience feels slightly less refined. Scans occasionally come out with a faint skew, and the wireless connection drops more often than I'd like. I have no scientific explanation for this. I do not mean it's unusable—I mean the polish is not the same, and polish matters when you scan 50 pages a day.
One workflow note: both ADFs handle standard copy paper fine. I've fed 20 lb and 24 lb stock through both without jams (note to self: don't test the ADF with spiral-bound meeting packets—I learned that one the hard way). Neither machine is a production scanner, but for a normal office workload, both get the job done.
Dimension 3: Maintenance and Reliability
The inkjet reputation for clogged printheads and streaky output is mostly earned, but not for the reason most people assume.
The WF-4730 uses two cartridges—black and a color combo—with the printhead built into the printer. When it clogs, a cleaning cycle clears it and consumes a little ink. That's normal maintenance, not a defect. The ET-4850 behaves the same way, with one catch I've noticed: because refill bottles are so cheap, people let tank printers sit idle for long stretches. An idle printer is a clogged printer, and a clogged printer makes people think the machine is broken. Print something at least once a week and you'll avoid most of these headaches on either model.
Paper handling is a wash. Both hold 250 sheets, both do automatic duplexing, and both sometimes eat a crinkled page that should have been thrown out (which, honestly, every printer does). Last year, a 40-page board packet needed printing with two hours before the CEO left for the airport. I skipped my usual test page. Page 30 jammed. In hindsight, I should have checked the tray for the damaged sheet from the night before. But with the CFO waiting, I just fixed it and moved on.
And for the office accidents nobody plans for: yes, I've had to look up how to remove permanent marker from a printer's casing. Someone labeled the paper tray with a Sharpie and the ink migrated onto the matte plastic. Rubbing alcohol on a microfiber cloth worked after a few gentle passes. Isopropyl alcohol won't hurt the casing if you don't scrub hard, but avoid acetone—it will melt the finish.
Dimension 4: Print Quality and Ink Chemistry
Here's the result that surprised me the most.
The WF-4730 uses DURABrite Ultra pigment ink. Pigment sits on top of the paper, which makes prints water-resistant. That matters more than you'd think. My office runs through coffee at an alarming rate, and pigment ink survives the occasional spill.
The ET-4850 uses dye-based color ink with a pigment black. Dye inks penetrate the paper, producing slightly more vibrant colors on glossy stock, but they run when they get wet.
For standard office documents—proposals, reports, client decks—both look professional. Text is crisp on both. Charts and graphs look good on both. But if you print labels, product sheets, or anything that might touch moisture, the WF-4730's pigment ink gives it a clear advantage.
The conventional wisdom says tank printers deliver the same print quality at lower cost. For photos, that's mostly true. For durability, the WorkForce Pro line wins because of the ink chemistry, not the printhead. I did not expect that conclusion when I started this comparison.
Which One Should You Order?
"Which is better" depends on your print volume, so here's the advice I'd give to another office buyer:
Choose the WF-4730 if:
- Your office prints under 300 pages a month
- You need a polished scanner workflow with a full-featured driver suite
- Water-resistant prints matter (labels, signs, anything carried around)
- You want the lower upfront price and don't want to think about ink economics
Choose an EcoTank (ET-4850 or similar) if:
- You print 500+ pages a month and want the lowest long-term cost
- Your team is comfortable with the bottle-refill routine
- Most of what you print is standard business documents on copy paper
I'll also say this as someone who manages a small-company budget: don't let anyone make you feel like your office's size means you shouldn't compare operating costs. Small doesn't mean unimportant. A printer is one of the few office purchases where the operating cost can exceed the purchase price within two years—that's true whether you're buying one machine or fifty.
Run the numbers for your own volume before you decide. Plug your page counts into a calculator, compare ink costs, and ignore the specs that don't affect how your team actually works. And keep the invoice and warranty documents where finance can find them—printers are one of the items our auditors actually check. That's the whole job, and it's worth doing before you spend $200 to save $20 a year in the wrong direction.
