printing wraparound labels with a pt7600

A bit like  https://wibblement.blogspot.com/2025/03/printing-cable-labels-with-pt7600.html , but printing just one wraparound label per id. Using the labeller's cutter, you would have to engage in the whole printing process, and cut when it says.  Doing it this way, you can quickly cut with scissors, either as a batch, or as you need them.  * prepare labeller: insert 9mm black on white tape, power on, ensure barcode PROTOCOL is set to CODE128  * press Code then Z to enter settings, and select CUT 2 using up and down, and hit return  * clear text with code, backspace, enter  * press "Bar Code" (confirm again it says CODE128)  * enter first id in sequence (you are managing ranges / sequences of ids elsewhere), for example "wibble1234", press return  * press Code -> Label Type  * it says Copies 1.  Press 2  * press right arrow and it goes to NUMBER OFF  * press down for 99, or enter however many you want (we don't expect it to...

changing linux timezone

Easy way to change system timezone is to change where the /etc/localtime symlink points to, eg:     # ln -sf /usr/share/zoneinfo/America/St_Johns /etc/localtime 

difference between timezone and offset

This is something I tried and failed to explain to a Computer Science graduate some years ago.  The Computer Science graduate assumed I was trying to make a point about seconds difference between UTC and GMT.  No.  I hope this doesn't count as slop, but Gemini can put it pretty well: User Question 1 what is the conceptual difference betwen a timezone and an offset AI Response 1 While they both help us tell time across the globe, a time zone and an offset are fundamentally different concepts. An offset is a static mathematical calculation, while a time zone is a dynamic geographic region governed by local laws. What is an Offset? An offset is the exact amount of time added to or subtracted from Coordinated Universal Time (UTC) to get the local time. Format: It is always expressed as a plus or minus sign followed by hours and minutes (e.g., +01:00 or -05:00). Nature: It is purely digital and mathematical. Limitation: It does not account for daylight saving time (DST) o...

Taxi ranks without taxis

Today, Folkestone Central taxi rank does not have any taxis, in the early afternoon. Yesterday, Oxford train station taxi rank did not have any taxis, also early afternoon. Later, I had to explain multiple times to a taxi driver where Richer Sounds is. It’s on Botley Road, with a sign outside saying “Richer Sounds”, and large lettering on the building saying “Richer Sounds”. This is second tine in a row a taxi driver has failed to find it, and has instead placed a series of calls asking where it is.

“Are you travelling alone, Sir?”

Border crossings continue to get more unpleasant. Today at Heathrow: the first time i have been selected twice in one pass through a customs channel. “Excuse me sir, are you travelling alone?”.   Questions then include did i pack it myself, where i live, where I’m travelling to and from, have i been anywhere else, do i know what alcohol and tobacco allowances are, what cash do i have, what about controlled substances, blades, explosives, firearms, obscene material, etc? So far, UK border still compares favourably to Guernsey in the following ways: the Guernsey intimidation squad use high-pressure techniques like piling questions on top of each other, and repeat questions. UK so far gives time to answer each question. Guernsey goons will start searching bag without saying anything, and send items into room next door, without saying anything. UK will ask “may i search this”, “may i swab that”. They have the authority to anyway, but it lets the subject know what’s happening, and is go...

Diesel Crisis and Priority Boarding

At Innsbruck airport, boarding is via a bus.  This bus crosses the tarmac, sometimes covering as little as twenty-five metres distance as the crow flies, but is mandatory. It's a two-carriage bendy bus. While the bus is boarding, it has all its doors open, and its diesel engine idling.  The diesel fumes come in to the bus, and the passengers breathe them.  Mentioning this to the driver does not result in the engine being turned off. Some passengers have "priority boarding".  This means they get to go first to the diesel bus, to breathe in the diesel exhaust for longer.  The ones without priority boarding stay longer in the lounge with the cafe.  Everyone ends up on the same bus. When the bus sets off, several people observe out loud what a tiny distance it covers.  Sometimes the bus does a big circle to make it seem longer. If Europeans want access to hydrocarbons again, maybe they should be more sensib le about diesel exhaust.  Just an idea.
