0a sends this print data to the external interface 34.
First, the directory information is formed on the removable medium 40 (step S10, step S11). Then, the received print data is stored in the removable medium 40 (step S12).
Here, the removable medium has an area for storing directory information and an area for storing print data, and the directory information indicates the storage position of the stored print data (see FIG. 7). Upon receiving the print data, the disk drive 30a acquires the print data from the printer interface 17 of the host device 1 by performing the same communication procedure as the printer.

The removable medium 40 storing the print data as described above is loaded into the disk drive 30.
The disk drive 30 on the printer 2 side is taken out from a.
When mounted on the printer b, print data is read out and output to the printer 2, and the printer 2 executes printing.

When the mounting of the removable medium 40 is detected, the directory information is read from the removable medium 40 (steps S21 and S22).
Then, the print data is accessed based on the directory information and the print data is read (step S2).
3). The print data thus read is output to the printer 2 via the external interface 34 (step S24).

The printer 2 receives the print data thus output via the host interface 26, and executes printing based on the received print data. Here, the output of the print data is performed in a predetermined procedure with the printer 2. That is, the disk drive 30b takes the place of the host device 1. When the printing of the print data by the printer 2 is completed, the presence of other data is determined from the directory information. If another print job exists, the process returns to step S22, and the print processing is performed on the other data. On the other hand, if there is no other data, this process ends.

By the setting of a switch (not shown), it is possible to select a mode in which the removable medium is ejected from the disk drive 30b when the output is finished or a mode in which the removable medium is left as it is. When the printing is completed, the removable medium is automatically ejected, so that it is possible to know the end of the printing and at the same time to omit the operation for taking out the removable medium.

A plurality of print jobs written from the host machine to the removable medium can be stored as long as the capacity of the removable medium is not exceeded. When a removable disk in which a plurality of print jobs are written is inserted into the disk drive 30b on the printer 2 side, all the stored print jobs are sequentially processed and output.

When printing is instructed by operating the input device 14 in the host device 1, print data including a print command is output from the printer interface 17. The output print data is compressed by the data compression unit 203. The compressed data is written to the removable medium set in the disk drive 30a via the data line 204. This removable media is a disk drive 3
When it is taken out from the storage medium 0a and set in the disk drive 30b, the compressed print data is read from the removable medium and is output to the data decompression unit 209 via the data line 210. The compression / decompression unit 209 decompresses the compressed data and outputs it to the printer 2. Printer 2
Receives the decompressed data and executes printing based on the data.

As described above, according to the second embodiment, since the compressed data is stored in the removable medium, it is possible to store the print data having a larger capacity.

A plurality of print jobs may be stored as shown in the first embodiment. In this case, since the directory information is generated in the disk drive 30a, the directory information is not compressed, but since the capacity of the directory information is much smaller than the print data, the influence on the storage capacity of the print data is neglected. It is possible.

The print data including the print command is written through the data line 302 to the removable medium set in the disk drive 30a. The removable medium may be a floppy disk, a magneto-optical disk, a removable disk, or other media.
When this removable medium is taken out of the disk drive 30a and set in the disk drive 30b, print data including a print command for the removable medium is read out and output to the printer 2.

Further, when outputting the check data, if that is set in the printer driver (not shown) installed in the host device 1, the output data is reduced by software to create the data, and the network interface 16 And via the network 305,
It is output by the checking printer 306.

Then, the printer driver 601 compares this data amount with a preset threshold value, and if the data amount is smaller than the threshold value, the data output path is automatically set to the network 50.
Set to 1. Therefore, the print data having a smaller data amount than the predetermined amount is output to the printer 2 without passing through the removable medium. The printer 2 receives print data via the network interface 25 and executes printing. On the other hand, when the amount of print data is larger than the threshold value, the print data is sent to the printer 2 via the removable medium as in the first embodiment.
