A single test label can print perfectly and still fall apart once you try to batch-print a real manifest of 50 or 100 orders. Batch printing puts more strain on drivers, spoolers and buffers than a one-off print, and that's exactly where a handful of common settings mistakes surface.
Wrong media type selected
If your driver is set to thermal transfer with no ribbon loaded — or the reverse — a single test print might still look fine by luck of timing, but a batch will reveal the mismatch quickly through blank or inconsistent labels. This is the same root cause covered in our Click & Drop troubleshooting guide, and it's worth checking before every batch if you've recently changed printers or label stock.
Page size mismatch
A driver configured for a page size that doesn't match your physical label roll will scale or crop every single label in the batch the same way — meaning if the first one has a clipped barcode, all hundred will. Confirm the driver's label size matches your loaded stock (100 × 150mm for standard UK shipping labels) before starting a large print run, not after.
Print spooler overload
Sending a very large batch to print all at once can overwhelm a USB printer's buffer on some driver/OS combinations, causing the job to stall partway through with no error message. Printing in smaller batches of 10–20 labels, particularly on USB rather than network connections, tends to be more reliable for high-volume days — a related issue covered in our printer jamming guide.
Outdated drivers
Printer manufacturers — Zebra, Citizen, TSC and Brother all included — release driver updates that specifically improve batch-printing stability and fix known bugs with certain operating system versions. If a printer that used to batch-print reliably suddenly starts stalling after a Windows or macOS update, checking for a driver update is one of the first things worth trying.
A quick pre-batch checklist
Before a large print run: confirm media type matches your label stock, confirm page size matches the physical roll, confirm the driver is current, and print one test label from the actual batch file rather than a generic test page. Thirty seconds of checking here saves far more time than troubleshooting mid-batch, especially during a busy dispatch window — see our guide on bulk printing for peak season for more on scaling this up.
Consistent stock, fewer surprises
Our rolls are manufactured to a single consistent spec, so once your driver settings are right, they stay right batch after batch.
