Available fonts This test will help you to check the current print quality and the
available fonts. The print-out of available fonts covers one page and
ends automatically, but can also be cancelled prematurely by pres-
sing the SEL button.
• Font test on a cut sheet
You can obtain a print-out of all available fonts by holding down
the LF button when switching on the printer. Either insert a cut
sheet or press the FF/LOAD button to have a sheet fed from the
cut sheet feeder (CSF).
• Font test on continuous paper
First mount the continuous paper in the tractor feed. Notes on
the use of continuous paper are to be found in the chapter »Pa-
per handling«. Hold down the LF button when switching on the
printer.
Should you wish to check the data being sent by the computer to the
printer, use the hexadecimal output. All data sent to the printer
including text and printer commands will then be printed in he-
xadecimal form and ASCII format, with all codes that are non-prin-
table in ASCII format shown as dots.
To activate this mode, hold down the FF/LOAD button and the SEL
button when switching on the printer. For this test too, you can use
the different methods described for feeding cut sheets and conti-
nuous paper.
The line of BASIC:
10 LPRINT CHR$(27); “0”; CHR$(30); This is an example of a
hexadecimal dump!”
would be printed as follows:

Should you wish to return to normal print mode, switch the printer
off and on again.
