PK-232 MBX – OPERATING MANUAL FACSIMILE OPERATION
4/91 9-4 107
The PK-232 will wait until it receives the synchronization signal from a facsimile station be-
fore beginning to print again.
9.5 Facsimile Operating Tips
The following section contains tips and information on FAX reception for those printing di-
rectly to a graphics printer. If you are using Timewave HF Wefax or AEA PAKRATT WITH FAX
program, consult the program manual for more information and helpful hints.
9.5.1 Setting PRTYPE for Your Printer
Before FAX can be printed on the printer you have connected, you must choose the cor-
rect printer type with the PRTYPE Command. Most printers these days support either the
Epson or the IBM bit-image graphics formats. For this reason the PK-232 defaults to the
Epson format. See the PRTYPE command in the Command Summary if your printer does
not support the Epson graphics standard.
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 sim-
ply 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 com-
mand. 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 Com-
mand 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 al-
so 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
