Print cheaply to a fast thermal printer. Thermal paper doesn't use ink and costs very little.  Black and White only.

Load log files

Load and monitor any text file, particularly log files which grow in size.  Print42 will detect any changes and display them - scrolling them into view.  Known as 'tailing'.

Print just the selected text or image

Reprint selected text.  Or reprint selected image(s).

Tail serious log files

Load and monitor large files.  Change font size.

Filter log files so that only text lines matching your filter appear or get printed to thermal tape.

No need to print a page at a time, the thermal printer ESCPOS driver will allow the printing of one line at a time.

Paste any image

Great for taking screen shots of any size and rapidly printing them.
