The GPT -437x-FLASH-USB meets the USB specificati-
on V1.1 for full-speed devices. The printer is compatib-
le to USB V2.0 bus systems. The USB device class is
equivalent to a "V endor Specific Device". Ther efor e,
transmission can be done with virtual COM port dri-
vers.
The printer will operate like a serial printer . The virtual
COM port drivers ar e available for the operating sys-
tems Windows 98/98SE/ME/2000, and XP , and pos-
sibly WinCE fr om the thir d quarter of 2004. For Linux
V2.40 and up, ther e is a dir ect Ker nel support. Ther efo-
r e, a driver is not r equir ed. Standar d GeBE printer dri-
vers can be used.
Operation
If a sleep mode has been selected for the printer , it will
switch to sleep mode after the pr eset time period has
passed. The USB interface, however , r emains active,
being dir ectly fed fr om the USB bus. A new print job
with the standar d driver r eactivates the printer without
any loss of data. The USB suspend mode also has the
printer inter nal USB interface tur ned of f. In this mode,
the printer will "go to sleep" after the pr eset sleep time.
