HP 3630 Printer vs HP Deskjet 2755e: Label Makers, Printable Graph Paper & Ruler Decimals

Every purchase request I receive at a 60-person company arrives with the same assumption: the lowest number on the price tag is the best deal. Ten years of managing office supplies has taught me otherwise. So this article compares four printing decisions I actually had to make—the HP 3630 printer vs the HP Deskjet 2755e wireless all-in-one printer, a label maker vs printable label sheets, printable graph paper vs pre-printed pads, and how to read a ruler in inches decimals. The ruler looks out of place. It isn't.

HP 3630 vs HP Deskjet 2755e: The Sticker Price Is the Weakest Metric

Our office ran the HP 3630 printer for years. I want to say we bought the first one in early 2020, but don't quote me on the month. It was a plain all-in-one—scan, copy, print—with a flatbed and a paper tray that always worked. Not fast, not flashy. Around $90 at the time, and finance approved it without a single follow-up question.

The HP Deskjet 2755e wireless all-in-one printer looks like a step down. Lighter plastic, a 60-sheet tray, no automatic document feeder, no fax. It sells for $60 or less. My first thought was that it belonged in a dorm room, not an office. That was a misjudgment, but not for the reason you'd expect.

Put the two side by side for a year, and the real comparison isn't the hardware—it's the ink economics.

The cheaper printer is the more expensive one to feed.

The 2755e takes the small HP 67 cartridge. About $15 for roughly 120 black pages, so that's over 12 cents a page if you buy it at retail. The 3630 takes a bigger cartridge and gets closer to 190–200 pages for the same kind of money—around 8 cents a page. The gap doesn't sound violent until you run a few thousand pages a year; then the "budget" printer quietly costs your department $80–100 more in ink.

The exception is the subscription. The 2755e is built around HP+ and Instant Ink, where you pay a flat monthly fee based on page count and HP ships cartridges before you run out (note to self: re-read the Instant Ink price sheet before our trial converts). The pricing is transparent and the calculation is simple. I have a love-hate relationship with subscriptions. What I mean is, I hate committing to them, and I love never running urgent ink errands in the middle of a workday.

The conclusion surprised me. If you'll ride the subscription, the 2755e is an honest, predictable deal for a small team. If you'd rather buy cartridges the old-fashioned way, skip it—retail 67 cartridges turn a $60 printer into the highest per-page cost in the building. The 3630, with its bigger cartridge, is the better buy on pure economics and it doesn't tie your purchasing to a cloud account. My money goes to the 3630 for anything above maybe 100 pages a month.

Label Maker vs Printable Labels: Which One Earns Its Desk Space?

The operations team asked me for a label maker. They'd seen demos, the laminated tags, the tidy cable labels. The device was $40—affordable—so the PO went through without my usual pushback. The problem arrived three weeks later, at restocking time: replacement tape runs $15–25 per roll, and because tape widths are limited, you end up buying multiple rolls to cover different jobs. The machine is the cheap part. The tape is the commitment.

Meanwhile, I'd been printing shipping labels through the HP printer on generic full-sheet label stock. A pack of 30-per-sheet labels costs about $15 for 100 sheets, which is roughly 3,000 labels. Add ink and it's still a few cents per label—with our logo, a QR code, and whatever dimensions we want. I set up a 4 x 6-inch template once and it's handled every mailing since.

When I compared the two side by side on the shipping table, I understood something I'd missed in the catalog: a label maker is a single-purpose tool that is extremely fast at one thing—small text on a fixed-width strip. Printable labels are a general-purpose system that does everything else. For customer-facing shipping labels, the HP printer won by a mile. For ethernet cable tags, the label maker is perfect. In our office, the label maker now lives on the IT shelf, and the shipping station uses printable labels.

If you print your own labels, two details matter. First, check the size against the envelope or box you're mailing in—USPS publishes envelope dimension standards (usps.com/businessmail101), and a label that's out of proportion on a standard flat looks sloppy. Second, export your label template at 300 DPI or higher. Text at 150 DPI looks sharp on a monitor and fuzzy on paper; at 300 DPI it holds up.

Printable Graph Paper vs Pre-Printed Pads: The Cost Nobody Estimates

Our engineering team kept ordering graph paper pads from the catalog—$5 to $8 per 50-sheet pad, standard grid, they vanish within weeks. I assumed printing our own would burn more money and tie up the printer. I ran the numbers, and I was wrong.

A $5 pad is 10 cents a sheet. A printed sheet is under a cent of paper (a $4 ream of 500 sheets) plus maybe a cent or two of ink: call it 3 cents a sheet, max. And you get to choose the grid. Half-inch, millimeter, dot grid, a custom pitch that matches the project—pre-printed pads give you one grid in one color; printable templates give you anything you can find or create. If you want the printed sheets to feel like a proper pad, feed them 24 lb bond (about 90 gsm) instead of standard 20 lb copy paper, and they'll lie flat and hold ink better.

The catch is scale. If your print dialog says "fit to page" or "scale to printable area," a designed 1-inch grid will come out at 0.98 or 1.03 inches. Tiny, but it compounds across 20 squares until your margins are visibly wrong. So you print one test page and measure it with a ruler before you run 200 copies. That's where ruler decimals come in—and why the next section is not as nerdy as it looks.

The conclusion flips at high volume: if your team uses 50-plus sheets a week, printing your own graph paper makes the shared printer the bottleneck and the ink spend stops being trivial. Buy the pads for daily drafting, keep printable templates for custom grids and occasional use. In other words, the "free" templates aren't free, but they're still usually the cheaper option.

How to Read a Ruler in Inches Decimals: Fractions vs Decimals

A standard ruler divides each inch into 16 ticks. Reading it as a fraction is simple: count the ticks past the whole inch, put that number over 16. Reading it as a decimal is what your template software and print dialogs expect.

Example: the edge of your test print lands 7 ticks past the 1-inch mark. That's 1 and 7/16 inches. Divide 7 by 16 and you get 0.4375, so the measurement is 1.4375 inches. Here's the full conversion for every mark on a 16-tick ruler:

1/16  = 0.0625     9/16  = 0.5625
1/8   = 0.125      5/8   = 0.625
3/16  = 0.1875     11/16 = 0.6875
1/4   = 0.25       3/4   = 0.75
5/16  = 0.3125     13/16 = 0.8125
3/8   = 0.375      7/8   = 0.875
7/16  = 0.4375     15/16 = 0.9375
1/2   = 0.5        1     = 1.0

Fractions are fine for the human eye. Decimals are what the software expects. If a template calls for 0.3125 inches and you type 0.3, you've introduced a 0.0125-inch error—small on its own, but multiply it across 20 grid squares and your final line drifts by a quarter of an inch. That's how a label loses its border, or a printed grid stops being trustworthy.

What I'd Buy in Your Situation

If you run a small team that prints under 100 pages a week and wants predictable ink costs: get the HP Deskjet 2755e, embrace the HP+ subscription, keep full-sheet label stock for shipping, and print graph paper on demand. Keep the decimal conversion chart above the printer for the monthly scale check.

If you run a larger office where finance audits per-page costs and the printer gets used all day: buy the HP 3630, skip the subscription, and accept that it costs a little more at the register because it will cost less over a full year of printing. Use 20 lb or 24 lb bond paper (about 75–90 gsm) so the sheets behave in the tray and in binders.

For the label maker question, decide based on the labels themselves. Cable tags, shelf strips, small fixed-width text: buy the label maker. Shipping labels, address blocks, anything with a logo: print them on full-sheet label stock with your HP printer.

And before you order any of it, ask what's NOT included. The $60 printer with the $15 short-life cartridge, the $40 label maker with the $25 tape roll, the "free" graph paper that runs on office ink—the real cost is whatever someone left off the first quote. It took me an embarrassing number of purchase orders to learn that, and it saves us money every time I remember to ask.
