Usage: escputil [-c | -n | -a | -i | -o | -s | -d | -l | -M]\n\

Perform maintenance on EPSON Stylus (R) printers.\n\
Examples: escputil --clean-head --printer stpex-on-third-floor\n\

Commands:\n\
-c|--clean-head Clean the print head.\n\

-a|--align-head Align the print head. CAUTION: Misuse of this\n\
utility may result in poor print quality and/or\n\
damage to the printer.\n\
-o|--align-color Align the color print head (Stylus Color 480 and 580\n\
only). CAUTION: Misuse of this utility may result in\n\
poor print quality and/or damage to the printer.\n\
-s|--status Retrieve printer status.\n\
-i|--ink-level Obtain the ink level from the printer. This requires\n\

This utility lets you align the print head of your Epson Stylus inkjet\n\
printer. Misuse of this utility may cause your print quality to degrade\n\
and possibly damage your printer. This utility has not been reviewed by\n\
Seiko Epson for correctness, and is offered with no warranty at all. The\n\
entire risk of using this utility lies with you.\n\
\n\
This utility prints %d test patterns. Each pattern looks very similar.\n\
The patterns consist of a series of pairs of vertical lines that overlap.\n\
Below each pair of lines is a number between %d and %d.\n\
\n\
When you inspect the pairs of lines, you should find the pair of lines that\n\
is best in alignment, that is, that best forms a single vertical line.\n\
Inspect the pairs very carefully to find the best match. Using a loupe\n\
or magnifying glass is recommended for the most critical inspection.\n\
It is also suggested that you use a good quality paper for the test,\n\
so that the lines are well-formed and do not spread through the paper.\n\
After picking the number matching the best pair, place the paper back in\n\
the paper input tray before typing it in.\n\
\n\
Each pattern is similar, but later patterns use finer dots for more\n\
critical alignment. You must run all of the passes to correctly align your\n\
printer. After running all the alignment passes, the alignment\n\
patterns will be printed once more. You should find that the middle-most\n\
pair (#%d out of the %d) is the best for all patterns.\n\
\n\
After the passes are printed once more, you will be offered the\n\
choices of (s)aving the result in the printer, (r)epeating the process,\n\
or (q)uitting without saving. Quitting will not restore the previous\n\
settings, but powering the printer off and back on will. If you quit,\n\
you must repeat the entire process if you wish to later save the results.\n\

That is, it prints one pattern and ejects the page. You must then reinsert\n\
the same page, and it will print another pattern. Each pattern consists of\n\
a set of choices numbered between %d and %d.\n\
\n\
When you inspect the patterns, you should find one patch to have the\n\
smoothest texture (least ``grain''). You should inspect the patches very\n\
carefully to choose the best one. We suggest using Photo Quality Inkjet\n\
Paper or a similar high quality paper for this test. If you do not find\n\
a smooth pattern, you should repeat the test.\n\
