'''To change the sticker roll'''
* The non-transparent paper labels don't come off easily. After peeling off parts of it, you might have to use a solvent or duct tape to completely remove the remains.

'''Software'''
==== Debugging ====
* If you feel like adding or improving a feature, the Stikka Printa source code can be found at https://github.com/5shekel/printit
* The software sometimes chokes on large, high-frequency print jobs, and no more stikkas are coming through. In that case, the easiest is to briefly power-cycle the Raspberry controlling Stikka Printa.
* If Stikka Printa isn't accessible on the known URL, the Raspberry controlling it might not be turned on, could have gotten a new IP from DHCP, or init5.ch DNS could be broken. Start by ensuring both the Raspberry and Brother QL550 are turned on, and scanning the BW network range for port 8980 using something like: nmap -sS -p 8980 --open -oG - 10.168.0.0/24. Once recovered, please print a new QR label in case the URL has changed, and update the link in this Wiki 🙏

Caveats

  • The non-transparent paper labels don't come off easily. After peeling off parts of it, you might have to use a solvent or duct tape to completely remove the remains.

Changing supplies

  • Open the cover
  • Pull orange lever up
  • Remove previous roll
  • Insert new roll
  • Feed new roll through front feeder
  • Push orange lever back down
  • Close cover

Debugging

  • The software sometimes chokes on large, high-frequency print jobs, and no more stikkas are coming through. In that case, the easiest is to briefly power-cycle the Raspberry controlling Stikka Printa.
  • If Stikka Printa isn't accessible on the known URL, the Raspberry controlling it might not be turned on, could have gotten a new IP from DHCP, or init5.ch DNS could be broken. Start by ensuring both the Raspberry and Brother QL550 are turned on, and scanning the BW network range for port 8980 using something like: nmap -sS -p 8980 --open -oG - 10.168.0.0/24.
