ZJ-5870 Thermal Printer

[wambiditu]

Manufacturer: ZiJiang (but mine is branded AGPtEK, and I have seen others as Esky)
Model: ZJ-5870
I could find no guide online.
Paper Width: 58mm

Based on the test bin files, I conclude:

Bit-Image: yes (without wide or tall)
Graphics: no
Barcode: no
QR-Code: no
PDF417-Code: no
Margins and Spacing: no
Partial Cut: no
Full Cut: no
Underline: light and heavy
Text Width: 1x, 2x, 3x, 4x, 5x, 6x
Text Height: 1x, 2x
Character Encodings: Danish, German, English, Spanish, French
Character Encodings: Irish Gaelic, Hungarian, Icelandic, Russian
Character Encodings: Japanese Katakana Half-width
Character Tables: 0 - CP437, 1 - CP932, 2 - CP850, 3 - CP860, 4 - CP863
Character Tables: 5 - CP865, 16 - CP1252, 17 - CP866, 18 - CP852
I think the Japanese table may not be entirely correct, but it does have the Katakana Half-width.

Thanks for posting @wambiditu

The code page list is much shorter than POS-5890, also by Zjiang, did you get these by printing a test page?

[wambiditu]

When I printed the printer test page by holding down the feed button during power-on, it told me that it could do many different code pages. However, when I compared what characters were actually printed under those conditions (using one of the bin test files, and also under my own testing) I discovered that most of those code pages were simply copies of one of the first listed code pages, and didn't actually do anything differently. So I omitted those from the list.

(Unfortunately, yesterday I managed to turn my 5870 into a smoking melted ashtray due to a buffer overflow, under which condition this printer seems to simply freeze up while continuing to heat the print head forever. Hopefully the 5890 I ordered has either a larger buffer, or a safer response to this situation. Regardless, I'll handle overflows better myself.)
