Testing the Printer
Run this test to check the printer. The test prints the settings for several functions, prints all
variations of the character sets, and partially cuts the paper between each variation. See the
"Diagnostics" chapter for a description of the functions.
A sample printout (RS-232C) is shown later in this section. The printouts for other models
are similar. The test ends with a partial cut, then begins again. Several feet of paper can be
used to print one pass of the test.
Running the test is slightly different for printers receiving power from the host computer
and printers receiving power from a power supply.
Additional diagnostic tests may be performed. For more information, see "Diagnostics"
later in this book.
