Serial Printer Cable Pinout. 
Figure 1 shows the pinout of commercially available cables like 
the Belkin

 F2V088-06 "6FT MAC MODEM DIN8M/DB25M" 
cable, described as "This modem cable interfaces the 
Mac+/SE/IIGS and Mac series II computers to all Apple 
peripherals with 8 pin mini din serial ports." 
 
Mac serial printer cables differ from Mac modem cables in that 
they are null-modem-style cables. Therefore a Mac modem cable 
cannot be used (alone) to connect a DeskWriter to a PC. Belkin 
makes a very small number of mini-DIN-8-to-DB-25 Mac serial 
printer cables (e.g. F2V026-06), but they are configured to connect 
a mini-DIN-8 Mac to printers with a DB-25 female connector. 
Unfortunately this is the opposite of what we are looking for. 
 
It turns out that what is needed to connect a DeskWriter to a PC is 
combination of the Apple modem cable and a null-modem cable 
(fully wired). As a test, we connected a DeskWriter 660C to a PC's 
COM2 serial port (DB-9 male) with the following cables and 
adapters: 
 
• Apple modem cable (min-DIN-8 male, DB-25 male) 
• gender changer adapter (DB-25 female, DB-25 
female) 
• adapter (DB-25 male, DB-9 male ) 
• null modem cable (DB-9 female, DB-9 female) 
 
Note
 A simpler cable can be assembled with, for example, an 
Apple modem cable and a null-modem cable with female DB-25 
connectors on both ends.  
 
If you'd like to make your own mini-DIN-8-to-DB-9 printer cable 
and you're handy with a soldering iron, refer to Figure 2.
