PK-232 MBX Operating Manual - N3UJJ

9.5.2 Printing Direction (LEFTRITE)
Weather FAX as well as most other facsimile prints from left to right,
but occasionally you may find a station that is reversed. If you come
across such a transmission , you may simply issue the command LEFTRITE
OFF to correct this. The PK-232 will respond with:
LEftrite now OFF
9.5.3 Inverting Black and White (FAXNEG)
You may occasionally come across a station that appears to be
inverted; that is printing black where you expect white, and leaving
white where you expect black. In this case you may issue the command
FAXNEG ON. The PK-232 will respond with:
FAXNeg now ON
What was before printing black will now be white, and vice versa.
9.5.4 Printing Density (GRAPHICS)
How the graphics will look on your printer depends on the setting of
the GRAPHICS command. There are 7 graphics commands providing
horizontal dot densities from 480 dots to 1,920 dots horizontally
across a page. The default setting is 960 which Epson compatible
graphics printers can reproduce. See the GRAPHICS command description
in the Command Summary for a complete description of this command.
9.6 Printing Other Services
Most of the weather services in the US use a facsimile scan speed of
2-lines per Second, which corresponds to an FSPEED of 2 (Default).
Facsimile photographs often use 1-line per Second, which is an FSPEED
of 1. Some foreign services use speeds of 4-lines per Second, which
is an FSPEED of 4. Speeds of 1.5 and 3-lines per Second are also
supported. See the command summary in for more information on FSPEED.
When different horizontal scan speeds are used, the number of lines
per vertical inch can also vary. If nothing is done to change the
number of lines printed by the printer, the pictures may appear
squashed or elongated. The ASPECT command resolves this by allowing
from one to six lines to be printed out for every six lines received.
The default setting is ASPECT 2 which means that 2 out of 6, or 1 out
of every 3 horizontal lines is printed. This is the most common
setting you will use for WEFAX, but other services may require using
other values to print pictures without aspect ratio distortions.
9.7 Transmitting FAX
The PK-232 does support FAX transmission, but attempting to do this
without a Timewave HF Wefax or n AEA's PC-PAKRATT II WITH FAX program
is difficult. We recommend you consider this program if FAX
transmission is desired.
