TIMEX Sinclair 2040
Thermal printer

Timex Sinclair 2040 printer is a rebranded Alphacom 32. It’s a thermal printer and uses paper rolls 4.33 inches by 82 feet long. Originally it would be a 40-column printer but ended up as a 32-column.

It connects to the computer’s edge connector (compatible with TS1000/1500/2048/2068) and has a pass-through to allow the use of other peripherals. Need a 24-26V AC Power Adapter.


  • 8×8 character matrix
  • 32 characters per line
  • 10 characters per inch
  • 8 lines per inch

Sixteen thermal heads produce the dots. Each head produces two characters for a total of 256 dots for each line. At the end of each line the paper is advanced vertically by one dot. The paper is the same as used by Alphacom 40 column printers made to work with other brands of computers such as Atari.

ZX BASIC commands LPRINT and LLIST directed output to the printer and COPY did a screen dump.

All the Timex catalogs shows a silver version, but those were never released. Later printers had the label changed to Timex Printer 2040.
