This POS display has a code page that identifies itself only as "Europe", and prints these characters:

af-240-europe

The code page does not match any that I can find with iconv. I'm tracking this code page in the database as "OXHOO-EUROPEAN", on the assumption that it is vendor-specific.

The task here is to identify each character and fill in the blanks. I got this far defining it:

OXHOO-EUROPEAN:
  name: Oxhoo-specific European
  data:
    - "ÇüéâäàåçêëèïîìÄÅ"
    - "ÉæÆôöòûùÿÖÜñѪº¿"
    - "áíóú¢£¥₧ƒ¡ÃãÕõØø"
    - "·¨°`´½¼×÷≤≥«»≠√¯"
    - "⌠⌡∞◤↵↑↓→←┌┐└┘•®©"
    # Some unidentified chars
    - "™†§¶Γ◢Θ         "
    - "ß   ε           "
    - "τ               "

Here's a best attempt:

        - "ÇüéâäàåçêëèïîìÄÅ"
        - "ÉæÆôöòûùÿÖÜñѪº¿"
        - "áíóú¢£¥₧ƒ¡ÃãÕõØø"
        - "·¨°`´½¼×÷≤≥«»≠√¯"
        - "⌠⌡∞∇↵↑↓→←┌┐└┘•®©"
        - "™†§¶ΓΔΘΛΞΠΣΤΦΨΩα"
        - "ßγδεζηθικλμνξπρσ"
        - "τυχψω▼▶◀␍↤␊⇥∏━ⓈⓅ"

Notes particularly about last line:

∇Δ - Note these are changed from your original. Given positioning in table, the first should be a math operator, and the second should be a greek letter. ◸◿ also exist as visual matches.
R,F - I'm guessing these are meant to represent meant to represent ␍␊ carriage return (\r) + line feed (\n). It's also possible they are "Reverse/Rewind" and "(Fast-)Forward". There's no exact match in standard Unicode. Some alternate possibilities:
  - ⓇⒻ Though I've used these for S/P (see below)
  - ⏪⏩ but visually they don't match.
  - Triple-byte 𝐑 and 𝐅.
∏ - No perfect fit here. The character used is a math symbol (N-Ary Product). There doesn't seem to be box/typography chars which look visually the same, the closest are  ␣ (widely used/typography), ⎴ (technical), ⊓ (math), ⺆ (CJK, this one's a stretch).
ⓈⓅ - I'm not sure the reason for S and P here. My guess is that it is to render "SP" (space) as two chars. I've chosen the more common Unicode two-byte chars ⓈⓅ as the mapping. There are also 🆂 🅿 which are visually more accurate but are triple-byte. Note there is also single-char ␠.
