Print a Bulk Barcode Label Sheet from a Purchase Order

An open purchase order can build a bulk label sheet from its saved lines. The batch follows ordered quantities and stored barcodes, so review both before printing.

Choose the Correct Label Workflow

Need	Use	Why
One label for every unit originally ordered	Purchase order -> Print labels	Copies come automatically from each order line's ordered quantity.
Labels for only the quantity physically received	Item-level Print Barcode	The purchase-order batch does not use received quantity.
A custom number of copies	Item-level Print Barcode	Order printing does not provide a copy-count dialog.
Labels from a received-purchase document	Item-level Print Barcode	Received purchases do not expose the purchase-order batch action.
A mixed subset of order lines	Item-level Print Barcode	The order batch includes every coded line until the global cap is reached.

Prepare Barcode-Ready Order Lines

Open Purchase -> Purchases and locate the exact purchase-order number.
Open the order and verify Supplier, status and item lines.
For every line to be labelled, confirm the item had a valid stored barcode when the order was saved.
Check the ordered quantity because it controls the number of copies.
Compare ordered and received quantities; stop if labels are intended only for arrived stock.
Correct item barcode data and the editable order before printing when the plan is still Draft or Ordered.
Use item-level printing when the order can no longer be edited or only selected copies are needed.

Print the Order Label Sheet

Open the purchase order document.
Click Print labels.
Allow the new print window when the browser asks or blocks it.
Review the preview title, item names, visible barcode values and total number of label cells.
Choose the installed label printer and correct paper size in the browser print dialog.
Print a short test when using a new printer, roll or scaling setting.
Scan the test label into a neutral input or Posnic item search and verify the exact item.
Print the remaining sheet only after the test passes.

How Copy Quantities Are Calculated

For each line with a non-empty saved barcode, Posnic rounds the ordered quantity to the nearest whole number and prints at least one copy. It stops adding labels when the combined sheet reaches 500 cells.

Saved ordered quantity	Calculated copies	Operator implication
1	1	One label for that coded line.
5	5	Five copies, even if fewer units have arrived.
2.4	2	Fractional quantities are rounded; use item-level printing for deliberate copy control.
2.6	3	Rounding can create more labels than a physical fractional quantity suggests.
0, blank or invalid	1	The client falls back to one copy for a coded line.
Any lines after sheet reaches 500	0	The global cap truncates the remaining batch without creating more cells.

Barcode and Layout Rules

Only the barcode value saved on the purchase-order line is used; SKU is not substituted by this print function.
Blank barcode lines are skipped entirely and counted by line, not by missing copies.
Unique barcode graphics are rendered once with the bundled JsBarcode library and reused for copies.
The requested format is CODE128 with the text value displayed below the bars.
Each label cell is 38 mm wide with 2 mm padding in the generated sheet.
Item names use a small single line and are truncated visually when too long.
Dotted cell borders appear on screen but are removed by print CSS.

Understand Warnings and Limits

Message or condition	Meaning	Correction
No lines with a barcode to print	Every order line has a blank barcode value.	Add and verify item barcodes, then update the editable order or print from item records.
N line(s) had no barcode and were skipped	At least one coded line printed, but N uncoded order lines were omitted.	Identify omitted items and print them only after barcode setup is corrected.
Allow pop-ups to print labels	The browser blocked the plain print window.	Allow pop-ups for the trusted Posnic origin and retry once.
Sheet ends before all ordered units	The combined job reached the 500-label cap.	Split the work into controlled item-level batches and reconcile quantities.
Barcode area is blank for a coded line	CODE128 rendering rejected or failed for that value.	Validate the barcode characters and print from the item after correction.
Print dialog does not open	The print window opened but browser printing was blocked or delayed.	Bring the print tab forward and use the browser Print command after confirming its content.

Stock and Audit Boundary

Printing labels does not receive goods, change available quantity or create an inventory log.
The batch uses qty_ordered, not qty_received or outstanding quantity.
A Draft, Ordered, Partial, Closed or Cancelled order with item lines can expose Print labels in the current interface.
A printed label is not proof that the item arrived or passed a physical count.
Keep the purchase-order number with the label run when shop procedure requires reconciliation.
After goods arrive, use Receive and Inventory Logs as the stock evidence.

Label Printing Problems and Corrections

Problem	Likely reason	Correction
Too many labels printed	Ordered quantity exceeded the arrived or intended label quantity.	Stop the job and use item-level copy counts based on the verified physical receipt.
Too few labels printed	Uncoded lines were skipped, quantities rounded, or the 500 cap was reached.	Reconcile each order line and print controlled remainder batches from item records.
Scanner opens wrong item	Duplicate or incorrect barcode data exists.	Stop distribution, correct item barcode ownership and retest before reprinting.
Labels are clipped	Browser scale, margins or printer stock size does not match 38 mm cells.	Use actual-size scaling where appropriate and test one page with the installed media.
Only SKU exists	This batch does not fall back from barcode to SKU.	Store the intended scannable value in Barcode, then update the order while editable.
Received purchase has no Print labels	Bulk printing belongs to purchase orders, not received-purchase documents.	Use the received purchase as a checklist and print from each item.
Reprinting may duplicate labels	Posnic does not record consumed or already-printed copy counts.	Mark the physical batch externally and reconcile before repeating the action.
