Labeljoy can print and export without opening its window: from a script, a scheduled task, or another program that needs labels. You type a command in a command prompt, and the document is printed or exported with the settings saved in it - or with the ones you change for that run.
Printing takes the document and nothing else:
LabeljoyX /p "C:\Labels\Shipping.ljx"
Exporting also needs what to export, /em, and where, /et:
LabeljoyX /e "C:\Labels\Shipping.ljx" /em=0 /et=C:\Out\Shipping.pdf
| How a command is written | |
| The document | Right after /p or /e, in quotes. |
| A switch | A slash, two letters, an equals sign and the value: /cp=2 prints two copies. The order doesn't matter. |
| Values | Without quotes, even with spaces in them: /pn=Office printer 2. Quotes work too. A slash in a value is fine, but not at the start of a word: that starts the next switch. |
| Yes or no | 1 is no, 2 is yes. |
The installer makes LabeljoyX work in any command prompt. Type LabeljoyX /? for a short summary of the switches.
| Printing | |
| /pn | The printer, by its exact name as Windows shows it. |
| /cp | Copies, from 1. |
| /ct | Collate: 1 no, 2 yes. |
| /bw | 1 grayscale, 2 color. |
| /ds | 1 one sided, 2 both sides flipped on the long edge, 3 both sides flipped on the short edge. |
| Exporting | |
| /em | What to export: 0 pages, 1 a label set, 2 an element. Required. |
| /et | The file to write, in a folder that already exists. Required. Its extension is replaced by the format's. |
| /ef | The format: pdf, png, jpg, webp, gif, tif or bmp. See File formats. |
| /dp | The resolution, from 72 to 1200 dpi. |
| /si, /ei | Which label set, and which element of it, counting from 1. |
| /fn | A field of the data source to name the files after. |
| /sp | One PDF per page or label: 1 no, 2 yes. |
| /of, /od | Open the file, or its folder, when it's done: 1 no, 2 yes. |
| Both | |
| /rg | Pages: all, or the first and the last, as in /rg=2:5. |
| /lg | Labels, the same way: /lg=1:40. |
| /lm | Label placement, for a label range: 0 start from first available position, 1 keep original start position, 2 full pages. See Print start position. |
| /aa | Auto-advance the page or label range after the run: 1 no, 2 yes. |
| /fp | The start position on the first sheet, row first: /fp=3:2 is row 3, column 2. all is the top left. |
| /up | Update the start position after the run: 1 no, 2 yes. |
| /ro | Rendering order: 1 across and then down, 2 down and then across. |
| /pw | The password, for a document protected against printing and exporting - see below. |
| /la | The language of the run's messages, by a two-letter code such as en, it, de, fr or es. |
Switches change that run only: the document keeps its own settings. After the run Labeljoy saves the document only to keep what the run moved on - the start position, an auto-advanced range, counters - so the next run carries on from there. A print without /rg or /lg uses the document's own range; an export without them exports all pages.
What you see. In a command prompt, Labeljoy writes what it's doing, and pressing a key cancels the job. When it ends, the exit code says how it went: 0 if it all worked, 1 if anything went wrong or was canceled - so a script can check. A mistake in the command, such as a switch that doesn't exist or a value it can't use, stops the run before anything is printed, with a message saying which switch is wrong.
Questions. A run asks what printing from the window would ask: the password, how many labels, the values the labels ask for, and the two warnings of the Print panel, unless you've hidden them. With nobody at the keyboard - a scheduled task, input from a file - every question counts as no, the run stops, and the exit code is 1.
The password. /pw takes the password's SHA-1 fingerprint, not the password itself, so it never sits in a script as plain text. In PowerShell, this prints the fingerprint of a password:
-join ([Security.Cryptography.SHA1]::Create().ComputeHash([Text.Encoding]::UTF8.GetBytes("your password")) | % { $_.ToString("x2") })
Want the command written for you? Ask Joy, the AI assistant: "give me a command line that prints this document on the office printer, two copies". It writes the line from the document you have open; it never puts a password in it.
A print started from the Print with Labeljoy menu of File Explorer, or from a print shortcut saved from the Save panel, works the same way. With no command prompt to write in, it shows a small window with the progress and any questions. Either way, a run is separate from Labeljoy's window: you can keep working in it while a script prints.
