FREE LABEL-PRINT CHECKS

How to check 4 × 6 inch shipping labels print the right size

Updated

A 4 × 6 inch label printer test PDF is a known 101.6 × 152.4 mm sheet, for checking that your setup keeps that size on paper. PrintBench prepares it free in your browser, with no account, and records what you measure.

Free to use. No account, email address or trial. Your checks stay in your browser.

Is 4 × 6 inches the same as 100 × 150 mm?

No. 4 × 6 inches is 101.6 × 152.4 mm, slightly larger than 100 × 150 mm, and PrintBench keeps them as separate test sheets. Choose the stock actually loaded, from its specification rather than the print queue's name. Selecting a nearby size or allowing Fit to Page can change the output even when the document looks right on screen.

How do I print it at the right size?

Choose 203 or 300 DPI to match the printer and download the verified test PDF. Print one copy at actual size or 100%, with 4 × 6 inch paper and the right orientation set in both the viewer and the driver, and Fit to Page turned off. Then confirm the sheet name printed on the label.

How do I check the printed label?

Measure the horizontal and vertical reference marks between tick centres and enter both; PrintBench checks each direction separately against the sheet's real dimensions. Record clipping or rotation as observations, then scan the Code 128 and QR codes with a keyboard scanner or the phone's camera and compare them with the known values.

Can I compare 4 × 6 inch and 100 × 150 mm stock?

Yes, as separate checks. Change the stock and prepare a new test: the earlier check keeps its own sheet, and the report keeps both sheet identities, so each measurement stays with the sheet it came from.

What PrintBench does not do

It does not connect to printers, inspect queues, calibrate hardware or discover the printer's DPI. A matching scan shows that the text arrived intact; it does not grade the barcode or confirm the page size, which is why the measurements are separate checks.

MADE FOR THE FLOOR

For teams using 4 × 6 inch label stock and checking page size, orientation, clipping or unexpected scaling.

A USEFUL STARTING POINT

Similar stock sizes need different PDFs

A 100 × 150 mm page is not the same size as a 4 × 6 inch page. PrintBench includes both as separate fixtures. Selecting a nearby size or allowing fit-to-page can change the output even when the document looks correct on screen.

FROM QUESTION TO EVIDENCE

Three steps to a useful result.

  1. 01

    Select 4 × 6 inches

    Choose the 4 × 6 profile in PrintBench and the appropriate 203 or 300 DPI fixture. Check the stock specification rather than relying on a queue's friendly name.

  2. 02

    Match the viewer and driver

    Set 4 × 6 inch paper dimensions, intended orientation and actual size or 100%. Print one copy and confirm the fixture identifier on the resulting label.

  3. 03

    Check both axes

    Measure the horizontal and vertical reference marks between tick centres. Record clipping or rotation separately. Then compare a scan from a keyboard scanner or the camera against the known Code 128 or QR value.

A CONCRETE EXAMPLE

A screen preview cannot confirm physical size

A PDF viewer can make different page sizes appear equally large on screen. The document's dimensions, the selected driver stock and the marks measured on paper provide different pieces of evidence. Record them together before changing another setting.

USED IN PRODUCTION

From a known test print to the right label on every job.

PrintBench checks one fixed test PDF on your printer. When each job needs its own label, LabelRules is the SmartFACT application for production labelling. It starts with an invited trial, with the first label workflow set up alongside your team.

Free tier

LabelRules

Describe label rules in plain English. Approved rules select each job’s layout, resolve customer codes and check required values before printing. LabelRules Free prints at an attended workstation, after the workstation, printer and stock have been checked. Pro adds connected triggers, routing and unattended printing.

BEFORE YOU START

A few practical answers.

Can I use the 4 × 6 test on 100 × 150 mm stock?

Choose the dedicated 100 × 150 mm fixture instead. Using a different-size page introduces another variable and can lead to fitting, clipping or scaling.

Does the 300 DPI choice change the page size?

No. Both fixtures retain the selected physical page dimensions. Resolution changes the source dot grid, including the realised lengths of reference marks.

Does a successful scan mean the setup is correct?

It means the received text matched the expected payload for that observation. Page size, scaling, print appearance and barcode quality require their own checks.

What are the current limits?

PrintBench checks the sheet you print, measure and scan on your own equipment; it does not certify a printer, driver or scanner. PrintBench itself does not connect to printers, inspect queues, calibrate hardware, grade barcodes, design custom labels or discover printer DPI. On a device with a camera, the camera button beside the scanner field reads the sheet's Code 128 and QR codes; a camera read shows the printed code can be read, and the keyboard scanner is checked by scanning with it. A session keeps up to five checks, with up to 50 scans in each. Its fixtures cannot check the size of CardBench's 100 × 50 mm cards. To send a test sheet straight to a printer, the optional Send to SmartFACT PrintStation link opens PrintStation in a new tab.

What happens to my data?

Measurements, notes and scan values stay in browser memory. The camera, when you use it, reads codes on your device: no image is stored or uploaded. No account or uploads are required. Test PDFs and preview assets load from this site. Downloaded reports are redacted by default; review before sharing. Reloading loses the session. Hosting may log ordinary requests. Google Analytics is optional and loads only after you accept. Use Analytics settings to change your choice.
