tain the actual ASCII character for ESC (0x1B), not the letters E-S-C .

Queries can be sent to the PK80 Printer via the Bluetooth or the RS-232
data link. The printer’s reply to a query r eturns information about the
printer or the printrequest. There are three steps involved:
1Frame your queryusing the correct command format.
2Send the Query (for example, via an applicati ons program or a terminal
emulator such as “Terminal” in the Windows Accessories group).
3Use the appropriatetable to interpret the printer’s reply.

Interpreting the Reply to a Query

Consult the table for each Query command to interpret the reply. Each
reply containsseveral pairs of letters. The first letter or “query character” is
separatedfrom the reply character by a colon (:) and the pair is followed
by a semicolon (;). Example: E:N; (part of the reply to a STATUS query).
According to the STATUS table, the Erefers to “errors“ in Easy Print
Commands. An Nmeans “no errors.”
